signal (SOURce<Ch>:CMODe:RPORt). The amplitude replaces the port amplitude (see
SOURce<Ch>:POWer<Pt>[:LEVel][:IMMediate][:AMPlitude] and related commands) as long as
the port signal is selected as a coherent signal (SOURce<Ch>:CMODe:PORT<Pt>[:STATe] ON).
<Ch>
Channel number. If unspecified the numeric suffix is set to 1.
<Pt>
Test port number of the analyzer.
<rel. amplitude>
Port-specific relative amplitude.
Range [def. unit]
–300 dB to +300 dB [dB]. UP and DOWN increment/decrement
the phase in 1-dB steps.
*RST value
0 dB
SCPI, Command Types
Device-specific, command or query
Example (for an analyzer with 3
or more ports):
*RST; SOUR:CMOD:RPOR 2
Reset the analyzer and select port 2 as the reference port.
SOUR:CMOD:PORT3 ON
Select the signal from port 3 as a coherent signal.
SOUR:CMOD:PORT3:AMPL 10; :PHAS 90
Select the signal from port 3 as a coherent signal.
SOUR:CMOD:REF VOLT
Assign the specified amplitude and phase relation to the voltage
of the coherent signals.
SOURce<Ch>:CMODe:PORT<Pt>:PHASe <rel. phase>
Defines the phase for the coherent signal at port no. <Pt> relative to the phase of the reference signal
(SOURce<Ch>:CMODe:RPORt).
<Ch>
Channel number. If unspecified the numeric suffix is set to 1.
<Pt>
Test port number of the analyzer.
<rel. phase>
Port-specific relative phase.
Range [def. unit]
–162 deg to +162 deg [deg]. UP and DOWN increment/decrement the phase
in 1-deg steps.
*RST value
0 deg

Types
Device-specific, command or query
Example:
See SOURce<Ch>:CMODe:PORT<Pt>:AMPlitude
SOURce<Ch>:CMODe:PORT<Pt>[:STATe] <Boolean>
Defines whether the signal at port <Pt> shall be coherent or non-coherent. In converter mode this
command is only applicable to converter ports and requires active power control for all converter ports (i.e.
SOURce:POWer:CONVerter:TRANsfer:DESCription must not be set to NONE).
