3.12 Monitor Spectrum Measurement
Notes If :INIT:CONT is ON, then a new continuous measurement will start immediately, with sweep (data
acquisition) occurring once the trigger condition has been met
If :INIT:CONT is OFF, then :INIT:IMM is used to start a single measurement, with sweep (data
acquisition) occurring once the trigger condition has been met
Dependencies For continuous measurement, :ABORt is equivalent to the Restart key
Not all measurements support this command
Status Bits/OPC
dependencies
The STATus:OPERation register bits 0 through 8 are cleared , except bit 6 (Waiting for Periodic
Sync). Initiating a measurement and Waiting for Periodic Sync could be asynchronous
The STATus:QUEStionable register bit 9 (INTegrity sum) is cleared
Since all the bits that feed into OPC are cleared by :ABORt, the Abort command will cause the *OPC
query to return true
Sweep Time Annotation (Remote Query Only)
Returns the Sweep Time Annotation value. Available only on non-sweeping
hardware.
This value is also displayed in the result trace window.
The value returned is the estimated turnaround time of each measurement cycle, in
seconds. The turnaround time is the sum of the signal acquisition time, FFT time,
and other overhead time, to complete the entire span of each measurement cycle.
Remote Command
[:SENSe]:<meas>:SWEep:ETIMe?
<meas> is the identifier for the current measurement; any one of CHPower-
|ACPower|OBWidth|MONitor
Example Channel Power measurement
:CHP:SWE:ETIMe?
Dependencies Available only on non-sweeping hardware
Preset Automatically calculated
3.12.9.2 Sweep Config
Accesses controls that enable you to configure the Sweep and Control functions of
the instrument, such as Sweep Rules.
Points
Sets the number of points taken per sweep, and displayed in the traces. The current
value of points is displayed parenthetically, next to the sweep time in the lower-right
corner of the display. Using more points provides greater resolution. Using fewer
