PXIe-4082 / PXIe-4072 Inductance Measurement High Test Time

[JessAndres]

I am currently using PXIe-4082 for Inductance measurement in LabVIEW 17.0 SP1, and measurement itself is taking 4-6s every time. Already tried all resolutions and still get the same result.

I would like to know if this is a bug with the SW / HW or is there any workaround to fix the problem?

What is the range of the measurement?

How did you wire your DUT?

Can you share your program? Have you tried with NI-DMM Soft Front Panel? How did you benchmark the test time?

[JessAndres]

The range is 100mH and 10mH. The DUT is wired through matrix connection and is being switch every time. The test time is timed manually in LabVIEW.

I tried using NI-DMM SFP and it shows the same behaviour. Found out that "Filter" enabled is causing the high measurement cycle time. Either disabling it or changing the Filter Settings to "1" will fix the problem. The main concern now is there's no access to this feature in the low-level driver and whenever you close the SFP it always reverts back to being enabled and Filter Settings to 4.
