STATus Subsystem
The STATus command subsystem enables you to examine the status of the
power meter by monitoring the following status registers:
• Device status register
• Operation status register
• Questionable status register
The contents of these and other registers in the power meter are
determined by one or more status registers.
Table 11- 25 summarizes the effects of various commands and events on
these status registers:
Tab le 11-25Commands and events affecting Status Register
The contents of the status registers are examined using the following
status register set commands:
:CONDition?
:ENABle <NRf>|<non-decimal numeric>
[:EVENt?]
:NTRansition <NRf>|<non-decimal numeric>
:PTRansition <NRf>|<non-decimal numeric>
Each of these can be used to examine any of the following eleven status
registers:
