Using *OPC? to
This example program demonstrates the use of the "OPC? to
Synchronize the HP
synchronize the controller with the E1440. It also shows how one
~1440~
can deal with the LIST subsystem which can sometimes be slightly
unwieldy.
The requirement is to set up a list sweep comprising:
rn one lin interval 1 MHz to 13 MHz , 1 second
one equi interval 13 MHz to 13 MHz , 2 seconds
rn one lin interval 13 MHz to 1 MHz , 1 second
one log interval 1 MHz to 13 MHz , 3 seconds
Output function is
SIN, amplitude is 5 V.
When the sweep stops we will print the message List sweep finished
on the computer screen
