SENSe Subsystem (Analog Demodulation, K7) R&S FSL
1300.2519.12 6.316 E-11
[SENSe:]ADEMod:PM:RPOint[:X]
This command determines the position where the phase of the PM–demodulated signal is set to
0 rad. The maximum possible value depends on the measurement time selected in the
instrument; this value is output in response to the query ADEM:PM:RPO:X? MAX.
Parameter
0 s to measurement time
Example
ADEM:PM:RPO 500us
Sets the position where the phase to 0 rad setting to 500 µs.
Characteristics
RST value: 0 s
SCPI: conform
Mode
ADEMOD
[SENSe:]ADEMod:RLENgth?
This command returns the record length set up for the current analog demodulation
measurement.
Example
ADEM:RLEN?
Returns the current record length.
Characteristics
*RST value: –
SCPI: device–specific
Mode
ADEMOD
[SENSe:]ADEMod:SET
This command configures the analog demodulator of the instrument.
Parameter
<sample rate> The frequency at which measurement values are taken from the
A/D–converter and stored in I/Q memory.
Allowed range: refer to chapter "Instrument Functions", section
"Analog Demodulation (Option K7)" – "Sample rate,
measurement time and trigger offset".
<record length> Number of samples to be stored in I/Q memory.
Allowed range:
1 to 400001 with AF filter or AF trigger active
1 to 480001 with both AF filter and AF trigger deactive
<trigger source> Selection of the trigger source to use for the demodulator.
Allowed values: IMMediate | EXTernal | IFPower | RFPower| AF
| AM | AMRelative | FM | PM (see note below)
<trigger slope> Used slope of the trigger signal.
