Appendix B Frequently Asked Questions
Caution When adding custom signal conditioning, do not exceed the components' power
dissipation ratings. Limit current into the BNC-2090A to ≤100 mA.
BNC-2090A User Manual
Can I use the SCXI resistor kit to build attenuators for my
BNC-2090A?
Yes. You can use the SCXI resistor kit, which consists of four high
precision 249 Ω resistors, to build attenuators (voltage dividers) for the
BNC-2090A. Refer to the
of Chapter 3, Signal Conditioning, for more information about building
attenuators for the BNC-2090A.
Can I configure the BNC-2090A to measure current?
Yes. You can use a pair of channels to route current through the a sense
resistor located in position E. Refer to the
Conditioning section of Chapter 3,
location of this component.
Set the SE/DIFF switch to SE mode and the RSE/NRSE switch to RSE.
This connects the BNC shields to AI GND. Configure the DAQ device for
a differential measurement across the sense resistor.
Can I attach 68-pin DAQ cables to the front and back of the
BNC-2090A to make it a pass-through?
Yes.
