SCPI Command Reference
Operating Manual 1145.1084.12 – 30 980
SCPI, Command
Types
Device-specific, command or query.
Example:
*RST; SOUR:FREQ:CONV:MIX:PAF –10
Reset the analyzer and specify a fixed Aux LO power of –10 dBm.
SENS:FREQ:CONV:MIX:APOR 1
Select the test setup where the additional mixers MEAS and REF are
connected to port 1 of the NWA.
SENS:FREQ:CONV:MIX:AINT 3
Select the analyzer port 3 as a source port for the Aux LO signal.
Alternatively, e.g. for a 2-port NWA in combination with an external
generator:
SYST:COMM:RDEV:GEN1:DEF 'Ext. Gen. 1', 'SME02', 'gpib0', '21'
Configure an R&S SME02 generator as external generator no. 1, assigning
the name Ext. Gen. 1 and a GPIB address 21.
FREQ:CONV:MIX:AEXT 1
Select the generator no. 1 as a signal source for the Aux LO signal.
SOURce<Ch>:FREQuency<Pt>:CONVersion:MIXer:PFIXed <fixed_power>
[Deprecated command, replaced by SOURce<Ch>:FREQuency<Pt>:CONVersion:MIXer:PMFixed]
Defines a fixed power, to be assigned either to the RF or to the LO signal (the signal not addressed by
SOURce<Ch>:]FREQuency:CONVersion:MIXer:FUDamental RF | LO).
<Ch>
Channel number
<Pt>
Physical port number of the analyzer. This suffix is ignored, because the port
assignments for mixer measurement are fixed.
<fixed_power>
Fixed power
Range [def. unit]
–40 dBm to +10 dBm. The exact range depends on the analyzer model or
external generator used; refer to the data sheet [dBm]. UP and DOWN
increment/decrement the source power in 0.1-dB steps.
*RST value
–25 dBm
SCPI, Command
Types
Device-specific, command or query.
Example:
*RST; SOUR:FREQ:CONV:MIX:PFIX –10
Reset the analyzer and specify a fixed power of –10 dBm.
SOUR:FREQ:CONV:MIX:FUND LO
Assign the channel base frequency to the LO signal. The fixed power is
automatically assigned to the RF signal.
