This subsystem controls the analyzer's mixer delay measurement mode. This mode requires options R&S ZVA-K9 and R&S ZVA-K4. Option R&S ZVA-K4 also provides Harmonic Distortion measurements, mixer measurements, arbitrary configuration of generator and receiver frequencies (Port Configuration), and intermodulation measurements.

Example: |
*RST; SENS1:FREQ:STAR 1 GHz; STOP 2 GHz Select a stimulus range between 1 GHz and 2 GHz. FREQ:MDEL:APER 1 MHz Select a 1 MHz aperture. FREQ:MDEL:UTON PORT, 3 Select NWA port 3 as a source port for the upper tone (no external generator). FREQ:MDEL:COMB ON Use the internal combiner to generate the two-tone signal at port 1 (for instruments equipped with the necessary options). ... (Perform mixer delay measurement, evaluate results.) FREQ:MDELay:CONV OFF Disable mixer delay measurement, switch back to normal (non frequency-converting) mode.
|
Enables constant mixer delay and defines a constant mixer delay value, to be used as a reference for a mixer delay measurement calibration.

Example: |
*RST; :FREQ:MDEL:CDEL 1 ns Enable constant mixer delay and define a constant mixer delay value of 1 ns. FREQ:MDEL:CDM? Query whether the constant delay mode is active. The response is 1.
|
Selects constant or variable delay for the mixer delay calibration.

|
Qualifies whether the analyzer applies the current mixer delay meas. calibration data.
The analyzer automatically applies the calibration data
when a calibration file is loaded (MMEMory:LOAD:MDCData)
or after a calibration sweep has been completed ([SENSe<Ch>:]FREQuency:MDELay:ACQuire).
|
<Ch> |
Channel number.
|
|
<Boolean> |
ON | OFF – Apply / ignore calibration data |
|
*RST value |
OFF
|
|
SCPI, Command Types |
Device-specific, command or query.
|
|
Example: |
|
Enables or disables the division of loaded mixer delay calibration data by two.
|
<Ch> |
Channel number.
|
|
<Boolean> |
ON | OFF – Enable / disable division |
|
*RST value |
OFF
|
|
SCPI, Command Types |
Device-specific, command or query.
|
|
Example: |
|
Selects the measurement setup/receiver configuration for the mixer delay measurement.
|
<Ch> |
Channel number.
|
|
Parameters |
INTernal –
internal receiver (one network analyzer only)
|
|
*RST value |
INTernal

|
|
Example: |
|
Selects the LAN connection for the mixer delay measurement with external receiver. The command has no effect if a single analyzer (internal receiver) is used.
|

Channel number.
|
|
Parameters |

|
|
*RST value |
LAN1
