TRACe<n>:IQ:RLENgth <NoOfSamples>
This command sets the record length for the acquired I/Q data. Increasing the record
length automatically also increases the measurement time.
Note: Alternatively, you can define the measurement time using the SENS:SWE:TIME
command.
Suffix:
<n>
.

Parameters:
<NoOfSamples> Number of measurement values to record.
Range: 1 ... 209715200(= 200*1024*1024);
*RST: 691
Example:
TRAC:IQ:RLEN 256
Manual operation: See "Record Length" on page 460
TRACe<n>:IQ:SET
NORM,<Placeholder>, <SampleRate>, <TriggerMode>,
<TriggerSlope>, <PretriggerSamp>, <NumberSamples>
This command defines the settings of the R&S ESR hardware for the measurement of
I/Q data. This allows setting the sample rate, trigger conditions and the record length.
If this command is omitted, the current instrument settings are used for the correspond-
ing parameters.
This command switches to IQ mode automatically (see also TRACe<n>:IQ[:STATe]
on page 898).
The trigger level can be set using the TRIGger<n>[:SEQuence]:SOURce command.
Note: When using the default settings with the TRACe<n>:IQ:DATA command, the
following minimum buffer sizes for the response data are recommended: ASCII format
10 kBytes, Binary format 2 kBytes.
Tip: To determine the trigger point in the sample (for "External" or "IF Power" trigger
mode), use the TRACe<n>:IQ:TPISample? on page 899 command.
Parameters:
NORM is not evaluated, but must be inserted
<Placeholder> numeric value
is not evaluated, but must be inserted
<TriggerMode> IMMediate | EXTernal | IFPower | BBPower | PSE
Selection of the trigger source used for the measurement.
For IMM mode, gating is automatically deactivated.
