[SENSe:]CORRection:CVL:SNUMber
<SerialNo>
This command defines the serial number of the mixer for which the conversion loss
table is to be used. This setting is checked against the current mixer setting before the
table can be assigned to the range.
Before this command can be performed, the conversion loss table must be selected
(see
This command is only available with option B21 (External Mixer) installed.
Parameters:
<SerialNo>
Serial number with a maximum of 16 characters
Example:
CORR:CVL:SEL 'LOSS_TAB_4'
Selects the conversion loss table.
CORR:CVL:MIX '123.4567'

Programming example: working with an external mixer
This example demonstrates how to work with an external mixer in a remote environ-
ment. It is performed in the Spectrum application in the default layout configuration.
Note that without a real input signal and connected mixer, this measurement will not
return useful results.
//--------------Preparing the instrument -----------
//Reset the instrument
*RST
//Activate the use of the connected external mixer.
SENS:MIX ON
//----------- Configuring basic mixer behavior -------------
//Set the LO level of the mixer's LO port to 15 dBm.
SENS:MIX:LOP 15dBm
//Set the bias current to -1 mA .
SENS:MIX:BIAS:LOW -1mA
//----------- Configuring the mixer and band settings -------------
//Use band "V" to full possible range extent for assigned harmonic (6).
SENS:MIX:HARM:BAND V
SENS:MIX:RFOV ON
//Query the possible range
SENS:MIX:FREQ:STAR?
//Result: 47480000000 (47.48 GHz)
SENS:MIX:FREQ:STOP?
//Result: 138020000000 (138.02 GHz)
//Use a 3-port mixer type
SENS:MIX:PORT 3
//Split the frequency range into two ranges;
//range 1 covers 47.48 GHz GHz to 80 GHz; harmonic 6, average conv. loss of 20 dB
//range 2 covers 80 GHz to 138.02 GHz; harmonic 8, average conv.loss of 30 dB
