BK Precision 4075B Series Arbitrary/Function Waveform Generators

4075B Series Arbitrary/Function Waveform Generators



The 4075B Series Arbitrary/Function Waveform Generators are versatile high-performance  single- and dual-channel arbitrary waveform  generators with large arbitrary memory depth. The instruments provide variable output voltages from 0 to 10 Vp-p into 50 ohms or up to 20 Vp-p into open circuit and a continuously variable DC offset that allows the output to be injected directly into circuits at the correct bias level.

These generators combine the benefits of DDS (direct digital synthesis) and true AWG (arbitrary waveform generator) architectures without the  limitations of either. Standard waveforms such as sine, square, and triangle are generated with a DDS chip, delivering great frequency resolution at a low cost. Custom arbitrary waveform generation is implemented with a true point-by-point design, offering improved signal integrity by producing significantly less jitter and distortion compared  to a DDS-only architecture. This point-by-pointgeneration capability allows these instruments  to be used for simulating reliable clock signals,  generating triggers, or validating serial data buses.

Additionally, these generators can be used with B&K Precision’s waveform editing software WaveXpress to create complex arbitrary  waveforms.

Extensive features such as internal or external  AM, FM, and FSK modulation along with  versatile sweep capabilities and variable edge pulse generation make these generators suitable for a wide range of applications.

What it is

The new SignalTEK CT issues a PDF report to prove that your installed data cables can carry Gigabit Ethernet traffic at full speed with no errors, and confirms correct wiremap results.

For installers, this means having a cost-effective way to demonstrate that the copper cabling was installed correctly and is capable of supporting Ethernet applications. By proving real world performance, SignalTEK CT confirms a professional job – reducing the risk of call backs.

SignalTEK CT also gives network owners the assurance that installed cabling will support bandwidth hungry services like VoIP, IP CCTV and video streaming following moves, adds and changes.

  • Fast – Autotest provides proof of copper cable performance in three simple steps.
  • Performance – Second handset allows Gigabit data traffic to be transmitted in a real world scenario.
  • Intuitive – Automatic generation of PDF reports uploaded to USB memory stick without a PC.
  • Dependable – Test to the IEEE802.3ab standard.

Today’s challenge

The foundation of all Ethernet networks is the physical cabling. As networks become faster and more complex they become more susceptible to disruption from external interference as well as faulty cabling and or connectors. These physical layer problems can cause a high number of server re-transmissions resulting in network drop-out or slow connection speeds.

If network performance issues are to be avoided, today’s installers and technicians need test equipment that not only verifies correct wiring but also confirms a link’s ability to transmit data at full rate.

Tomorrow‘s solution

Uniquely SignalTEK CT proves a link’s ability to support Gigabit applications by performing two primary tests; data transmission and wiremap testing.

With a single press of the Autotest button, SignalTEK CT transmits 823,452 data frames between the two handsets and reports any transmission errors against performance criteria laid down by the IEEE 802.3ab Gigabit Ethernet Standard.

It takes only 1 bit of data to get corrupted or lost to give rise to a transmission test failure.

Autotest also measures cable length and checks for wiring faults such as crossed pairs, opens, shorts and split pairs.

Simple pass/fail results are displayed once the Autotest is complete which can be automatically saved for later review or download.

The Kestrel 4600 Heat Stress Meter with Compass provides two vital functions in one unit. Determine appropriate exposure to heat stress conditions for occupations with heavy gear requirements, such as HAZMAT response and firefighting, AND utilize wind speed and direction for plume prediction and modeling. This meter also displays thermal work limit (“TWL”), another recognized composite heat stress prediction tool. Carry less equipment and get more accomplished quickly in emergency situations!

The Kestrel 4600 Heat Stress Meter is the most reliable heat safety meter for emergency response personnel, hazmat crews and others who need accurate, environmental readings in order to properly assess environmental conditions and personnel safety in the field.  The Kestrel 4600 offers protection to those are exposed to extreme conditions by providing real-time monitoring of indoor or outdoor conditions. 

Built tough enough to stand up to extreme hot and cold temperatures, the Kestrel 4600 is a rugged and easy-to-use handheld weather meter that monitors heat-related environmental conditions quickly with the touch of a button.  Easy to program and incredibly reliable in the field, the meter generates highly accurate Wet Bulb Globe Temperature (WBGT) readings within a single portable, lightweight device that doesn’t require any water or a complicated set up to use.

The Kestrel 4600 is used to determine exposure to heat stress conditions within minutes of exposure to the environment.  This handy, portable meter also lets users activate and set up to six customized heat stress warning zone thresholds to trigger onscreen notifications of dangerous conditions.  A valuable tool that can save a life out in the field or indoors in extremely hot and smoky conditions, the Kestrel 4600 Heat Stress Meter sounds an alarm when the WBGT reaches a desired threshold or when it enters into an unsafe range, allowing field personnel to get to safer conditions or to notify them to take a water break in order to avoid dehydration or other heat-related illnesses.  

For emergency personnel and hazmat crews, having to wear heavy gear combined with the constant threat of fire, chemical blasts or combustive materials can all contribute to the risk of heat-related injuries, including heat stress, heat stroke and even death.  Fortunately, these risks can be easily mitigated with consistent monitoring of heat-related environmental conditions.  The Kestrel 4600 Heat Stress tracker is the perfect tool for the job, offering precise readings and several easy to use functions that provide data right at your fingertips.  Easy to use and transport out in the field, the Kestrel 4600 Heat Stress Meter allows users to carry less equipment on the job while still getting all of the atmospheric data they need to properly assess conditions and monitor WBGT, the most common composite measurement used to determine exposure to heat stress conditions.

With the Kestrel 4600 Heat Stress instrument, firefighters, hazmat professionals, emergency services personnel and others who are risk of heat-related injuries due to exposures to extreme indoor and outdoor conditions can easily monitor conditions with real-time WBGT readings.  The lightweight, durable heat stress meter also includes a digital compass, allowing users to monitor wind direction for plume prediction.  The Kestrel 4600 Heat Stress Meter also comes with a compact (2.5 x 2.5 x 6 in.) padded carry case, and a portable vane mount that can be mounted on any tripod for hands-free monitoring. Bluetooth® enabled units can even transmit data to personnel inside a response vehicle.

The Kestrel 4600 heat stress tracker offers accurate and localized measurement of heat stress conditions which is a key component of a heat illness prevention plan. Human heat stress results from a combination of many environmental factors – air temperature and humidity along with radiant heat from the sun and surfaces, balanced by the cooling effect of breezes or air flow. Anyone who has stood under welcome shade adjacent to a sizzling parking lot understands that these conditions must be evaluated exactly where peoples' activities are taking place. The most common composite measurement used to determine appropriate exposure to heat stress conditions is Wet Bulb Globe Temperature or “WBGT." The American College of Sports Medicine, the American Conference "of Governmental Industrial Hygienists, and the US Military all have published threshold limit values (TLV's) or reference guidelines for conditions, activity levels and hydration based on WBGT, clothing levels and acclimatization of participants.
