Folks I am trying my best here but I keep coming up with questions.
I found a NI PCMCIA-GPIB card and have it running in my Laptop
The laptop is has the proper cable to connect to my 776 Keithley Counter
Time.
2 10 MHz signals into A and B inputs
Set the counter to phase of A to b and the degrees tick away
The NI communicator tells me that the IDN command was sent but no response.
BUT If I press the read command I a return from the counter that corresponds
to the reading on the counters LED display .
TI responds the same way, frequency works as well what ever mode I put the
776 in I get that back in the GPIB window along with the correct numerical
response.
Now I open TimeLab, Open the acquire screen, select GPIB listen only mode
Press the monitor key and there is a continual stream of values PHAS+
177.75e +0 CHANGING AS THE DISPLAY CHANGES incrementing the correct
direction.
Press measurement and the screen changes to "preparing acquisition" and
then stays there.
No acquisition takes place It just stay like that..
I am so close I can taste the data
Any help would be appreciated.
Thank you
