• Dual 4 Channel RF Multiplexer
• 2 GHz bandwidth, 50 Ohm
• Cascade together for up to 16:1 multiplexer

The Keysight DAQM905A RF multiplexer module Data Acquisition System offers broadband switching capabilities for high-frequency and pulsed signals. Use it to route test signals between your device under test and your signal generator, oscilloscope, spectrum analyzer, or other instrumentation.

The RF multiplexers are arranged as two independent 1 x 4 multiplexers, each with a common shield and a switched center conductor. Connections can be made directly to SMB inputs with 2 GHz usable bandwidth, or to the BNC-to-SMB adapters provided with 1 GHz bandwidth. Multiple banks may be cascaded together for applications requiring even larger topologies-- create a stubless 16:1 multiplexer in a single frame.

Standard Product Includes:

• 1 DAQM905A, Dual 4-Channel 50 Ohm RF Multiplexer Module
• 1 Functional Test Certificate
• 10 Cables, 50 Ohm (SMB to BNC)

• 16 bits of digital input and output
• 100 kHz totalizer input
• Two +/-12V analog outputs plus two voltage/current sensing channels
   

The Keysight DAQM907A module Data Acquisition System allows great flexibility for a variety of sense and control applications. It combines two 8-bit ports of digital input and output, a 100 kHz gated totalizer, and two ±12V analog outputs - all on a single earth-referenced module. The analog outputs have two additional voltage/current sensing channels. The digital inputs and totalizer input may be included in a scan. Alarm limits for the digital and event counter inputs are evaluated continuously, capturing and logging alarm conditions even between scans.

Digital Input/Output
Use the digital outputs with an external power supply to control microwave switches and attenuators, solenoids, power relays, indicators, and more. Use the digital inputs to sense limit switch and digital bus status. There are no complex handshake modes; reads and writes are initiated either from the front panel or the bus.

Totalize Input
Count events from devices like photo interrupters, limit switches, and Hall-effect sensors.
It keeps an updated total which can be read via the front panel or programmatically at any time. With 26 bits of resolution, it can count events at full speed for nearly 45 minutes without an overflow.

Analog Output
Use the two electronically calibrated analog outputs to source bias voltages to your device under test, to control your analog programmable power supplies, or use the outputs as setpoints for your control systems. The outputs are programmed directly in volts, either from the front panel or from the bus.
