4×8 Two-wire Matrix Switch
- 32 two-wire crosspoints
- 300 V, 1 A switching
- Includes Certificate of Calibration
The Keysight DAQM904A gives you the most flexible connection path between your device under test and your test equipment, allowing different instruments to be connected to multiple points on your DUT at the same time.
Rows or columns may be connected between multiple modules to build 8×8, 4×16 or larger matrices, with up to 96 crosspoints in a single frame.

HIGHLIGHTS
- The fastest throughput oscilloscope solution for triggering on and analyzing I²C, SPI, I²S, and RS232/422/485/UART serial buses
- Multiple Bus decode triggering and listing display
- Perform 2-wire, 3-wire, and 4-wire SPI serial protocol trigger and analysis
- On-screen serial decode time-correlated with the serial data waveforms
- For the InfiniIVision 3000A X-Series oscilloscopes, this package enables I²C, SPI, I²S, and RS232/422/485/UART serial trigger and decode, mask testing, enhanced HDTV video testing, and advanced math options
- For the InfiniIVision 3000T X-Series oscilloscopes, this package enables I²C, SPI, I²S, RS232/422/485/UART, and USB-PD serial trigger and decode, mask testing, frequency response analysis (bode plot), and enhanced HDTV video testing. Advanced math already comes standard on all 3000T X-Series oscilloscopes
The embedded software package for Keysight’s InfiniiVision 3000A X- and 3000T X-Series oscilloscopes enables protocol triggering and decode for a broad range of the most common serial buses used today for embedded and mixed-signal designs. This package also enables other advanced analysis capabilities including mask testing and frequency response analysis to help test today’s electronic designs.
