Keysight Technologies Data Acquisition Module for Use with 34970A or 34972A

Offering incomparable powerful measurement performance, connectivity options and flexibility, Keysight Technologies Data Acquisition Systems/Switch Units are leading the way in ease of use. Up to 3 modules can be inserted into a single mainframe in any combination without the need for additional software, due to the included BenchVue DAQ software provided when the 34970A or 34972A is purchased.

The 34901A module is an extremely versatile multiplexer built for scanning, addressing a broad range of data applications it features multi-function switching with 60 channel/second scan rates. On the same module 1 and 4 wire channels can be mixed, and ac/dc measurements are made possible through 2 additional fused inputs, eliminating the need for external shunt resistors. Keysight modules allow a user to choose between features, for example the 34901A has broad functionality and can be used to scan with external instruments also.

• Built-in cold junction reference
• 2 additional current channels (22 in total)
• 2 wire armature (4 wire selectable)
• 60 ch/sec speed
• 10 Mhz bandwidth
• < 3μV thermal offset
• No cables needed

Modules allows a user to customise Data Acquisition Systems/Switch units to meet their unique requirements like an adapter, more modules can also be added as a users application grows. With Keysight Technologies systems these modules slot easily in to the back of the system/unit. These systems have the DMM installed in the chassis, leaving the remaining 3 mainframe slots free, allowing users to choose between control and switch modules dependant on their need.

Keysight technologies provide 8 module accessories in total for the 34970A (810-5027) or 34972A (702-7958):

34901A 20 channel multiplexer (702-7939)
34902A 16 channel multiplexer (702-7932)
34903A 20 channel Actuator/GP Switch (702-7936)
34904A 4 x 8 Matrix (702-7945)
34905A Dual 4 channel RF Mux 50 Ω (702-7948)
34906A Dual 4 channel RF Mux 75 Ω (702-7942)
34907A Multifunction Module (702-7951)
34908A 40 channel Single-Ended Mux (702-7954)

Certificate of Calibration

This multiplexer from Keysight Technologies is designed for use with data acquisition or switch units. It lets you customise your system to monitor and control different parameters, such as temperature and current. As it has 20 channels, it can accommodate signals from 20 different inputs, making it a good choice for general scanning applications. Thanks to its fast scanning rate of 60 channels per second, it gives you quick results for improved productivity.

• Broad operating temperature range of 0°C to +55°C for use in demanding environments

• Furnace temperature monitoring
• Hydraulic cell arm load cell monitoring
• Turbine speed monitoring

A thermocouple is a sensor for measuring temperature. Its two wires are made of two different metals that are connected at two points. As the voltage between the two junctions is proportional to temperature, it can be measured to obtain a temperature reading.
