I am currently using HP VEE ver. 5.01.
I am developing an impedance test on 6 t-filters on a backplane
board utilizing a LCR meter from HP model# 4263B.
right now I can test one filter outside the board with a pass or fail
result. THis is done by using panel driver.
In a separate file, I perform an opens/shorts correction test
before I measure the impedance of the filter.
This is done by using direct I/O.
But I get eroneous data (real and imaginery and negative numbers and half
the values that expect) using direct I/O.
I get the expected values using panel driver but cant do open/shorts test.
IF I can do an opens/shorts correction using panel driver then I wouldnt
be having any problems.
how can I incorporate direct I/O and Panel driver
together? Will this cause a problem If I do.
please get back to me at your earliest convenience.

interface that this instrument is on. By doing this you can see the exact
SCPI commands the panel driver is sending. Compare them to the ones you are
sending in your Direct I/O and then you'll know why you get different
results.
