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

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

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

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
