Increasing the record length also increases the measurement time.
Note: Alternatively, you can define the measurement time using the SENS:SWE:TIME
command.
Parameters:
<NoOfSamples> Number of samples to record.
See Chapter 4.1.1, "Sample Rate and Maximum Usable I/Q
Bandwidth for RF Input", on page 21.
*RST: 1001
Example:
TRAC:IQ:RLEN 256
Manual operation: See " Record Length " on page 60
TRACe:IQ:SET <FilterType>, 0, <SampleRate>, <TriggerMode>, <TriggerSlope>,
<PretriggerSamp>, <NumberSamples>
This command sets up the R&S FSWP for I/Q measurements.
If you do not use this command to set up I/Q measurements, the R&S FSWP will use
its current settings for I/Q measurements.
If the I/Q Analyzer has not been turned on previously, the command also switches to
the I/Q Analyzer.
Note: If you use the default settings with TRACe:IQ:DATA?, the following minimum
buffer sizes for the response data are recommended:
ASCII format: 10 kBytes
4
Binary format: 2 kBytes
Parameters:
<FilterType>
<0> Default unit: HZ
This value is always 0.
<SampleRate> Sample rate for the data acquisition.
Range: 100 Hz to 10 GHz, continuously adjustable
*RST: 32000000
Default unit: HZ
<TriggerMode> Selection of the trigger source used for the measurement.
IMMediate | EXTernal | EXT2 | EXT3 | IFPower
For IMM mode, gating is automatically deactivated.
*RST: IMM
<TriggerSlope> Used trigger slope.
POSitive | NEGative
*RST: POS
