Ramsey Electronics STE3300F2 Microwave & RF Shielded Enclosure Designed for Forensics Testing

Ramsey Electronics STE3300F2 Microwave & RF Shielded Enclosure Designed for Forensics Testing

Microwave & RF Shielded Enclosure Designed for Forensics Testing

The STE3300F2 is designed specifically for storing multiple wireless devices in their powered-on state while keeping them isolated from the network carrier. Its larger size makes it ideal for extended storage of department confiscated devices both before and after the forensics examination for what could be an extended period of time.
Let’s follow a typical forensics time line.

  1. A suspect wireless device is confiscated on-site. To protect it from real-time on-line executable booby traps (remote kill commands, remote lock commands, remote self-destruct commands, etc.) as well as device GPS tracing back to your location, the device needs to be immediately isolated from the carrier’s network. It also needs to be isolated from any available WiFi source. That can be easily accomplished with the use of our STE2200F2 forensics enclosure or STP1100 series forensics pouch.
  2. Once the wireless device has reached your lab, it needs to be made ready for your forensics examination. However, the device still needs to be totally isolated from the carrier’s network and WiFi sources. But now the device needs to remain powered up to eliminate the liability of a very possible power-down lockout, power-down self-destruct script, or other power-down loss of integrity. Therefore, the device needs to be plugged into a charger to maintain its powered-up status. If a forensics interrogation is scheduled soon, the device can be transferred to, and plugged into a charger in our STE3000F2 series RF Test Enclosures. If the interrogation cannot be scheduled soon, and the device needs to be stored, it can be transferred into our STE3300F2 RF Test Enclosure, and connected to a charger to maintain its powered-up state until an interrogation can be scheduled.
  3. Whenever the interrogation is completed, if the device is to remain in custody, it can be transferred into our STE3300F2 enclosure, connected to a charger to maintain its powered-up status, and can be stored until further needed. At no time during this time line, was the wireless device exposed to the carrier’s network, a WiFi source, and was never in jeopardy of being blocked, locked out, or otherwise compromised by a network received or powered-down script.

Enclosure wise, the STE3300F2 is a twin to our STE3000F2 and STE3000FAV2, without the visual and hands-on capabilities, and without the video/audio recording system. It is designed to provide you ample room for multiple device storage, while keeping them in a powered-on state for as required. Like its twins, it comes standard with a 6-outlet 110VAC outlet strip to accommodate any combination of device chargers and multiple port USB based device chargers. Six of our optional 4-port USB chargers can be easily plugged in to charge 24 various formatted wireless devices! Also like its twins, a USB2.0 high speed interface is also provided as standard equipment with the STE3300F2. This gives you a fully RF isolated I/O at full 480mbps USB2.0 speed to interconnect with any device inside the enclosure. This is perfect for connecting a suspect device, already in your possession, to your forensics software tools for further investigation and data dumps, all of which can be done without relocating the device in question.

The RF filtered AC power interface as well as the USB2.0 interface are located on the spacious universal removable I/O panel. This leaves plenty of room for a host of other I/O options that you may need to suit your specific test applications. From international power options to virtually every data and RF interconnect, we have the option available that you require.

The STE3300F2 is designed around the same heavy duty, rugged .090” and .125” aluminum design of its STE3000F2 series twins. New for 2014 it also features our custom engineered GEN-2 RF gaskets. With over a year in the R&D lab, these new gaskets provide a previously unheard of and flawless RF seal while being immune to the fixed compression set of typical stainless gaskets. Likewise, also new for 2014 the STE3300F2 also features our ¾” GEN-2 RF absorbent and reflective foam lining. This foam was designed from the ground up, to our demanding specifications to provide maximum performance over all operating frequencies and bands. Therefore, you can be confident that any device in your possession will remain totally isolated from the carrier’s network, regardless of the carrier, make or model, operating system, or the frequency bands used. Likewise, the device will also remain fully isolated from any WiFi signal sources, including both 2.4 GHz and 5.0 GHz, and therefore covering any combination of 802.11a/b/g/n/ac protocols.

Like all of our forensics units, tamper-proof hardware and dual padlockable latches are designed into the STE3300F2 to prohibit unauthorized access and maintain the chain of custody for the devices collected and stored. If you or your department is looking for a secure RF isolated storage chamber for your confiscated wireless devices, check out the STE3300F2.

Testo 420 Flow Hood

Testo 420 Flow Hood

The Testo 420 Volume Flow Hood for larger air inlets and outlets enables fast and precise compliance with hygiene guidelines and requirements concerning room air quality. It provides reliable support with the calculation of the overall volume flow on HVAC systems, for instance in hospitals, office buildings or commercial buildings.

High measuring accuracy at swirl outlets thanks to volume flow straightener

Volume flow is frequently measured at swirl outlets. Air flows are often incorrectly measured due to the turbulent air at these outlets.

The testo 420 volume flow hood means you can significantly reduce these measurement errors. The integrated volume flow straightener calms the turbulence and converts it into a virtually uniform air flow. This enables accurate calculation of volume flow in the 80 to 3,500 m3/h range.

Exceptionally light volume flow hood with fast set-up

The volume flow hood with ergonomic handles and tiltable display has an exceptional weight of less than 2.9 kg. This means that frequent volume flow calculations in large rooms and measurements above head height can also be carried out reliably and comfortably. In the process, a large measuring button on the volume flow hood ensures easy recording of the readings.

The dimensions of the hood are 610 x 610 mm. We offer additional hoods as accessories for further ceiling outlets. The use of our optional tripod arm is a great help for air inlets and outlets which are located very high up. It can be extended up to 4 metres.

The volume flow hood is quick and easy to set up thanks to tension rods. The trolley which is included in the scope of delivery ensures safe transport.

Create protocols directly on site and mail them using the App connection

Take advantage of further practical functions and download our free App. Because the App connection enables mobile devices such as smartphones and tablets to be used as a secondary display and remote control via Bluetooth. This is particularly practical for using a tripod arm for high ceilings.

The App enables live measurement on HVAC systems using a start and stop function and the saving of measurement data in txt format. You can create the measurement protocol directly on site using the App. Measurement results, such as the overall volume flow and the air exchange rate, can be directly assigned to customer-specific protocol templates. You can then send your readings and protocols via the e-mail function. This means you save a considerable amount of time and increase efficiency.

Volume flow hood with removable measuring instrument – performance overview

The volume flow hood for HVAC systems is equipped with a measuring instrument for displaying measurement data. The device can be tilted and removed for user-friendly reading of measuring values.

The testo 420 measuring instrument enables you to measure flow velocity, volume flow, absolute pressure, temperature and relative humidity. The automatic zeroing ensures higher accuracy for low pressures.

All measuring values are easy to read on the large display which has an illumination function. For analyses and documentation, measurement data can be saved and measurement protocols created directly on site using the App connection. Administration of the measurement data is very easy on the PC without any additional software via the plug & play function.

The testo 420 volume flow hood with its integrated measuring instrument was not just developed for volume flow measurement at larger ceiling outlets. The measuring instrument can also be taken off the hood and used for pressure, flow and volume flow measurements in the duct. This means you can save on the purchase of an additional measuring instrument.

You merely have to attach a Pitot tube and connection hoses (both optional) for measurements in ducts. Timed and multi-point mean calculation, as well as the combination of the two, together with simple input of the duct geometry provide you with support for measurements in ducts.

SCPI Command Overview
SCPI (Standard Commands for Programmable Instruments) is a standardized instrument programming language that is built upon the standard IEEE488.1 and IEEE 488.2 and conforms to various standards (such as the floating point operation rules in IEEE754 standard, ISO646 7-bit coded character for information interchange (equivalent to ASCII programming)). This section introduces the syntax, symbols, parameters and abbreviation rules of the SCPI commands.

SCPI Status Registers
All the SCPI instruments execute the status register operations in the same way. The status system records the various instrument states into three register sets: status byte register, standard event register and questionable status register sets. The status byte register records the advanced summary information
reported by other register sets. The SCPI status systems of the DP800 series multi-channel models.

The DP800 Series Power Supplies combine the ability to source, analyze, and coordinate over time in a powerful new package. The DP800 Series is a family of linear power supplies systems with 3 outputs and up to 195 Watts in total. With one channel isolated users can reconfigure instruments into any number of systems or applications.

Built in V, A, and W measurements make power monitoring easy, but additional wave tracking, timing, and analysis features means there are even more ways to use the supplies. New digital triggering between instruments also makes it possible to reliably combine and connect supplies together. Intuitive to use for everything from education labs to the R & D bench, the DP800 family of power supplies provide incredible value for any application.

Measure with Unquestioned Truevolt Confidence

Worry about the quality of your design, not the  quality of your measurements

In a rack or on a bench real-world signals are never flat. They have some level of AC signal riding on top from power line noise, other environmental noise, or injected current from the meter itself. How well your meter deals with these extraneous factors and eliminates them from the true measurement makes a big dif- ference to your accuracy. Behind the scenes, Keysight’s Truevolt technology accounts for measurement errors created by these real-world factors so you can be confident in your measurements and it is only available on Keysight DMMs.

Truevolt technology starts with an analog-to-digital converter that enables a patented metrology-grade architecture. Using this architecture, Keysight delivers a good balance of measurement resolution, linearity, accuracy, and speed at a value price, all de- rived and guaranteed per ISO/IEC 17025 industry standards.

Measure with Unquestioned Truevolt Confidence

What Truevolt technology means to you:
You can measure your real-world signals, not instrument error
Noise and injected current: Keysight Truevolt DMMs contribute less than 30% of the injected current than alternatives. Compared to some lower cost alternatives, Truevolt DMMs offer almost 100% less noise.
Input bias current: Ideally, no current flows into the measurement terminals of your DMM. In real measurement situations, there are always input currents creating additional measurement errors. Truevolt DMMs take care of input bias current. Some alternative DMMs offer 20% to infinitely poorer performance (some are too noisy to measure).
Digital AC rms measurements: For meters in this class, only Keysight uses digital direct sampling techniques to make AC rms measurements. This results in a true rms calculation technique that avoids the slower response of analog RMS converters used in all other vendor’s 6½ digit DMMs. This allows for crest factors up to 10 without additional error terms. This is a unique, patented technique – only used by Keysight.

You can measure your real-world signals with confidence

All Truevolt DMM specifications are tested and guaranteed for compliance with ISO/ IEC 17025 standards so you can prove the effectiveness of your lab or production line’s quality management system. Many lower-cost DMMs in this class do not carry a guarantee of their measurement specifications.

You can take advantage of expanded measurement functionality

Compared to the 34401A DMM, Truevolt DMMs offer expanded current ranges from 100 µA to 10 A. We have also added a temperature measurement function (RTD/PT100, 5 kΩ thermistor). Additionally, diode measurement capability has been expanded to allow a larger full-scale voltage to be measured (5 V) to enable the measurement of more diode types such as LEDs.
