3 IQ Analyzer (Basic) Mode
3.1 Complex Spectrum Measurement
Command
:CALCulate:SPECtrum:MARKer[1]|2|…|12:TRACe SPECtrum | ASPectrum | I | Q | IQ
:CALCulate:SPECtrum:MARKer[1]|2|…|12:TRACe?
Streaming:
:CALCulate:STReaming:MARKer[1]|2|…|12:TRACe SPECtrum | ASPectrum | I | Q | IQ
:CALCulate:STReaming:MARKer[1]|2|…|12:TRACe?
Example
:CALC:SPEC:MARK:TRAC SPEC
:CALC:SPEC:MARK:TRAC?
Notes A marker may be placed on a blanked and/or inactive trace, even though the trace is not visible and/or
updating
An application may register a trace name to be displayed on the control instead of a trace number
Couplings The state of Marker Trace is not affected by Auto Couple
If a Marker Trace is chosen manually, Auto Initialize goes to OFF for that marker
Sending the remote command causes the addressed marker to become selected
Preset
SPECtrum
State Saved The Marker Trace and state of Auto Init for each marker is saved in instrument state
Min 1
Max 12
Marker Settings Diagram
Lets you configure the Marker system using a visual utility. It is the same as "Marker
Settings Diagram" on page 207 in Settings.
Marker Phase Value (Remote Query Only)
Returns the phase of the Spectrum trace at the point of the specified marker. The
unit is in radians, and will be a value between ±п or ±3.14. If the marker is inactive or
outside the range of the trace, the value 9.9E+37 is returned. This query is
essentially the same as locating the X position of the marker in the returned array
using :READ:SPEC10?.
If the specified marker is a Delta marker, this query returns the phase delta from the
reference marker.
Remote Command Complex Spectrum:
:CALCulate:SPECtrum:MARKer[1]|2|…|12:PHASe?
Streaming:
:CALCulate:STReaming:MARKer[1]|2|…|12:PHASe?
Example
:CALC:SPEC:MARK3:PHAS?
Dependencies Marker needs to be active, on the spectrum trace and within the range of the spectrum trace
