Hi Sir,

I would like to ask if is there any references or guide for troubleshooting our hp3070 Tester?

I encountered problem with our tester where in it fails in Setting up Power Supply for all the Fixture.Single or Double Bank

I already changed ASRU Card in Module 3 since it was failing in diagnostics(DUT Lead Resistance) but still come out this
Failure(2340-2341)
I Swapped DUT Supply at module 3 to the another Tester but still same.

And i noticed that when i test power supply without the Unit under test in the fixture ,it will still failed the same,and the value also same.

I hope you can help me with this matter thank you..

James

if this has just started - or always been there ?

You can also try to test the power supply in the system diagnostics, and check that the fans are working ok on the DUT PS

or can try to communicate with them over GPIB/HPIB using the btio command in shell, this will ensure you can communicate to the power supply

also DUT lead resistance failure, just generally can be a dirty MINT pins, or poor connection to the ASRU card - especially if it just marginally fails the DGN

The power supply are declared correctly in config file for testhead? The Cable that connect the power supply with ASRU card are with good connection? You tried to activate the power supply manually and measure the voltage with a multimeter on test pins? The GPIB address are correctly?

What is the actual failure message that you see when the power supply fails?

Another suspect is that the current drawn by the UUT is higher than the power supply can drive. Or sometimes boards experience a spike when the power is turned on that cause the power supply to go over-limit.

1) Try setting the current limit higher.
2) use an oscilloscope to monitor the current at the power supply probes
3) does the failure message say "over-current" failure?

When you swapped.
"I Swapped DUT Supply at module 3 to the another Tester but still same."
what was the same? The suspect power supply at the other tester fail or the tester with the power supply swapped in, fails.
