Automated Measurement Setup and Control
The HP-IB or LAN interfaces can also be used to trigger sweeps, read
measurement values, or signal events within the analyzer. Most
operations that can be done from the front panel can also be done over
the HP-IB or LAN interface. See the Programmer's Guide and the LAN
Interface User's Guide Supplement for details.
This chapter describes methods for changing instrument settings rapidly
under program control. It then briefly discusses how to synchronize the
modification of instrument settings with the collection of data and how to
use service requests (SRQs) to signal instrument states. Finally, it
describes how to utilize both measurement channels and a feature to
automatically start an IBASIC control program.
For information on techniques that can improve your sweep speed, refer
to "Optimizing Measurements" in your analyzer's User's Guide.
