Using Status Registers
The analyzer's status registers contain information about the condition
of the network analyzer and its measurements. This section describes
the registers and their use in GPIB programming.
Example programs using the status registers are included in the
Example Programs Guide. These programs include SRQ and GRAPHICS
which use service request interrupt routines, PASSCTRL which uses the
status byte to request control of the GPIB, and LIMITEST which uses the
Limit Fail condition register.
