TRACe<1|2>:IQ:SET <filter type>,<rbw>,<sample rate>,<trigger source>,<trigger slope>,
<pretrigger samples>,<# of samples>
This command defines the settings of the analyzer hardware for the measurement of I/Q data.
This allows setting the bandwidth of the analog filters in front of the A/D converter as well as setting
the sample rate, trigger conditions and the record length.
If this command is omitted, the current analyzer settings will be used for the corre-
sponding parameters.
Parameter: <filter type>: NORMAL
Selects the analog analyzer resolution filters as filter type. This is currently the only
available filter type.
<rbw>: Bandwidth of the analog filters in front of the A/D converter.
Value range: 300 kHz – 10 MHz in steps of 1, 2, 3, 5 and 20 MHz and 50 MHz for
<filter type> = NORMal
<sample rate>: Sampling rate for the data acquisition.
Value range: 10 kHz to 81,6 MHz for <filter type> = NORMal
<trigger mode>: Selection of the trigger source used for the measurement.
Values: IMMediate | EXTernal | IFPower
After selecting IFPower, the trigger threshold can be set with command TRIG:LEV:
IFP.
<trigger slope>: Used trigger slope.
Values: POSitive | NEGative
<pretrigger samples>: Number of measurement values to be recorded before the
trigger point.
Range: -16776703 (=-(16*1024*1024-1-512)) to 16776703 (=16*1024*1024-1-
512)
(Negative values correspond to a trigger delay.)
For <trigger mode> = IMMediate the value must be 0.
<# of samples>: Number of measurement values to record.
Value range: 1 to 16776704 (=16*1024*1024 - 512)
