Keysight (Agilent) DAQM901A 20 Channel Multiplexer (2/4-wire) (for DAQ970A & DAQ973A)
The Keysight (Agilent) DAQM901A 20 Channel Multiplexer is the most versatile multiplexer for general-purpose scanning. It combines dense, multi-function switching with 80 channel / second scan rates to address a broad spectrum of data acquisition applications. Two- and four-wire channels can be mixed on the same module. Two additional fused inputs (22 channels total) route up to 1 A of cur to the internal DMM, allowing ac and dc cur measurements without the need for external shunt resistors.
Specifications for the Keysight (Agilent) DAQM901A 20 Channel Multiplexer (2/4-wire) (for DAQ970A & DAQ973A) Include:
| Number of Channels | 20 |
| Scan rate | 80 channels/s |
| Maximum Current | 1A |
| Bandwidth | 10 MHz dB |
