3 IQ Analyzer (Basic) Mode
3.2 IQ Waveform Measurement
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
3.2.9.2 X Scale
Accesses controls that enable you to set the horizontal scale parameters.
Ref Value
Sets the display X reference value.
Remote
Command
:DISPlay:WAVeform:VIEW[1]|2:WINDow[1]:TRACe:X[:SCALe]:RLEVel <time>
:DISPlay:WAVeform:VIEW[1]|2:WINDow[1]:TRACe:X[:SCALe]:RLEVel?
Example
:DISP:WAV:VIEW:WIND:TRAC:X:RLEV 10 ms
:DISP:WAV:VIEW:WIND:TRAC:X:RLEV?
Notes View 1 is the RF Envelope View
View 2 is the I/Q Waveform View
Couplings If X "Auto Scaling" on page 408 is ON, this value is automatically determined by the measurement result.
When you set a value manually, X Auto Scaling automatically changes to OFF
Preset 0.000 s
State Saved Saved in instrument state
Min/Max -1 s /10.0 s
Annotation <value> s bottom left of graph
Scale/Div
Sets the display X scale/division value.
