3 IQ Analyzer (Basic) Mode
3.1 Complex Spectrum Measurement
If the instrument is set for Continuous measurement, it sets up the measurement
and initiates a new data measurement sequence with a new data acquisition
(sweep) taken once the trigger condition is met.
If the instrument is set for Single measurement, it remains in the "idle" state until an
:INIT:IMM command is received.
Remote Command
:ABORt
Example
:ABOR
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
3.1.9.3 X Scale
Accesses controls that enable you to set the horizontal scale parameters.
Ref Value
Lets you set the display X reference value. Only appears if the IQ Waveform window
is selected.
Remote
Command
Complex Spectrum:
:DISPlay:SPECtrum:VIEW[1]:WINDow2:TRACe:X[:SCALe]:RLEVel <time>
:DISPlay:SPECtrum:VIEW[1]:WINDow2:TRACe:X[:SCALe]:RLEVel?
Streaming:
:DISPlay:STReaming:VIEW[1]:WINDow2:TRACe:X[:SCALe]:RLEVel <time>
:DISPlay:STReaming:VIEW[1]:WINDow2:TRACe:X[:SCALe]:RLEVel?
Example
:DISP:SPEC:VIEW:WIND2:TRAC:X:RLEV 10
:DISP:SPEC:VIEW:WIND2:TRAC:X:RLEV?
Couplings If X "Auto Scaling" on page 279 is ON, this value is automatically determined by the measurement result.
When you set a value manually, X Auto Scaling automatically changes to OFF
