Measure Phase from Angilent 54622D ocsilloscope through serial port

[Anonymous]

Hi, I have a angilent oscilloscope connected in serial port with my
PC(my oscilloscope does not come with GPIB interface). I wish to
acquire the phase different measurment from this scope through serial
by using labview 7.0. I have downloaded the labview intsrument library
files for this equipment but can't find anything in the library
related to phase measurment. Can anyone guide me how to program using
labview through serial port interface to this equipment and measure
the phase difference between two signals? Another question is it
possible to use serial com and GPIB interface in a same VI program at
the same time? This is because my another two equipment HP33120A and
34401A is connected using GPIB cabl
e and my scope is the only
equipment that only has a serial port and parellel port for interface.

You should be able to use the cursors to get phase if there isn't a
built in measurment command for this). If you set the start cursor to
some point on channel one and the stop cursor on the same point of
channel 2, the delta t returned should allow you to calculate the
phase difference.

And yes, you can use GPIB and serial instruments in the same VI.
