Keysight Technologies Data Acquisition Multiplexer for Use with Data Acquisition & Switch Unit

The 34902A high-speed multiplexer features reed relays and is therefore able to achieve staggering scan rates of up to 250 channels per second. With a built-in thermocouple reference junction this fast device is also able to scan two and four wire, sixteen two-wire inputs switch up to 300V.

Applications include, high throughput automated tests, monitoring tasks and high speed data logging.

• 250 ch/sec
• 10MHz bandwidth
• < 6 μV thermal offset
• 2 wire reed, 4 wire selectable

The Keysight USB Data Acquisition (DAQ) family offers the choice and flexibility to create standalone or modular solutions that expand and evolve according to test requirements.

Also known as a mux or data selector, a multiplexer device is used to forward multiple digital and analog input signals in to one single output. in forwarding multiple signals in to one output, a multiplexer allows several signals to share one device. Demultiplexers or demux operate in reverse, they are often used for cost reduction in conjunction with one another, often within communication and data links.

Not recommended for connection to ac line without external transient suppression.

Dreaming of speedy signal transmission on your data acquisition systems? Let this multiplexer from Keysight Technologies make it a reality. Thanks to integrated reed relays, it can achieve a high scanning speed of 250 channels per second. This means it can read inputs at the drop of a hat, helping to increase productivity. Its 16-channel design gives this multiplexer the power to assess multiple devices at the same time, making it a versatile piece of kit.

• Rated load switch life of 100,000 operating cycles for long-term performance
• Broad operating temperature range between 0°C and +55°C for use in challenging settings
• Maximum switching voltage of 300V for use in low-voltage applications
• Supports two and four-wire scanning for versatility

• Automotive workshops
• Electrical laboratories
• Measurement and instrumentation

With this versatile unit, you can take temperature, voltage (AC and DC) and resistance readings. It can also assess frequency and period signals. Be sure to use a shunt resistor if you want to use it for current measurements.
