Example:
ADEM:RLEN?
Returns the current record length.
Usage: Query only
[SENSe:]ADEMod:SET <SampleRate> | <RecordLength> | <TriggerSource> |
<TriggerSlope> | <OffsetSamples> | <NoOfMeas>
This command configures the analog demodulator of the instrument.
Parameters:
<SampleRate> numeric value
The frequency at which measurement values are taken from the
A/D-converter and stored in I/Q memory.
Allowed range: refer to chapter 4.3, "Sample Rate, Measure-
ment Time and Trigger Offset", on page 29.
*RST: 8 MHz
<RecordLength> Number of samples to be stored in I/Q memory.
Range: 1 to 400001 with AF filter or AF trigger active, 1 to
480001 with both AF filter and AF trigger deactive
*RST: 501)
<TriggerSource> Selection of the trigger source to use for the demodulator. For
details on trigger sources see "Trigger Source" on page 95.
IMMediate | EXTernal | EXT2 | EXT3 | IFPower | RFPower| AF
| AM | AMRelative | FM | PM
Note: After selecting IF Power, the trigger threshold can be set
with the TRIGger[:SEQuence]:LEVel:IFPower command.
*RST: IMMediate
<TriggerSlope> POSitive | NEGative
Used slope of the trigger signal.
The value indicated here will be ignored for <trigger source> =
IMMediate.
*RST: POSitive
<OffsetSamples> Number of samples to be used as an offset to the trigger signal.
For details refer to chapter 4.3, "Sample Rate, Measurement
Time and Trigger Offset", on page 29.
The value indicated here is ignored for <trigger source> =
"IMMediate".
*RST: 0
<NoOfMeas> Number of repetitions of the measurement to be executed. The
value indicated here is especially necessary for the average/
maxhold/minhold function.
Range: 0 to 32767
*RST: 0
