Instek DAQ-904 – 4 x 8 Two-Wire Matrix

Description
Instek DAQ-904 – 4 x 8 Two-Wire Matrix
The Instek DAQ-904 module can provide the most flexible connection path between your DUT and the test system, allowing different test instruments to be connected to multiple points on the DUT at the same time. DAQ-904 can connect the rows and columns of multiple modules to build larger matrices, such as 8 x 8, 4 x 16, etc. Up to 96 cross-points can be built in a single instrument.
Please note: this item is only a module – mainframe is sold separately.
Several versions available
Instek offers several modules for use with its DAQ-9600 mainframe. The information below provides an overview of the main specifications for each. For more detailed information, please click here.

Note:
1. For the measurement of 100Ω and 1kΩ resistance ranges, it is recommended to use 4-wire resistance. The maximum resistance range of DAQ-900 is 1MΩ.
2. When measuring AC voltage, the input impedance will decrease with frequency. A source impedance of 5Ω or less will maintain specification over frequency. A source impedance of 50Ω or less will maintain specification in the 5 kHz range.
3. For DC voltage measurement, if the integration time is short and the source impedance is high, more stabilization time may be required.
