Pulsed ITM returns no data

Post by ondrejs » August 2nd, 2021, 5:14 pm

Hello,

We are trying to carry out pulsed IV measurements using ITM on a two-terminal device. However, no data are reported from the test (in the sheet or the graph), as if no measurements were executed at all.

The test runs quickly (1-2 seconds). It reports no error. We tried connecting DUT via 1-channel and 2 channel setups (of the same PMU). No success in either setup.

Any idea about possible cause?

Thx, -Ondrej

Attached screen shots after running the test, which show the definition of the test (1st image) and results (2nd image) which show that no data was collected.

The ITM definition seems fine.
Close KITE and invoke KCON. Run the selftest for the 4225-PMU. Any errors?
I am suspecting some sort of hardware malfunction.
