Remote Commands for Analog Demodulation Measurements
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
lation Bandwidth", on page 27.
*RST: 8 MHz
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)
Selection of the trigger source to use for the demodulator. For
details on trigger sources see
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
*RST: IMMediate
POSitive | NEGative
Used slope of the trigger signal.
The value indicated here will be ignored for <trigger source> =
IMMediate.
*RST: POSitive
Number of samples to be used as an offset to the trigger signal.
For details refer to Chapter 4.3, "Sample Rate and Demodula-
tion Bandwidth", on page 27.
The value indicated here is ignored for <trigger source> =
"IMMediate".
*RST: 0
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
ADEM:SET 8MHz,32000,EXT,POS,-500,30
Performs a measurement at:
sample rate = 8 MHz
record length = 32000
trigger source = EXTernal
trigger slope = POSitive
offset samples = -500 (500 samples before trigger occurred)
