TRACe Subsystem
6.246 Operating Manual 1164.4556.12 - 06
TRACe<1|2>:IQ:SRATe 15.625 kHz to 32 MHz
This command sets the sampling rate for the I/Q data acquisition. Thus the sample rate can be
modified without affecting the other settings.
Return value: 15.625 kHz, 31.25 kHz, 62.5 kHz, 125 kHz, 250 kHz, 500 kHz, 1 MHz, 2 MHz,
4 MHz, 8 MHz, 16 MHz, 32 MHz
Example:
TRAC:IQ:SRAT 4MHZ
Characteristics: *RST value: 32 MHz
SCPI: device-specific
Mode: A-T
TRACe<1|2>:IQ[:STATe] ON | OFF
This command switches the I/Q data acquisition on or off.
Example:
TRAC:IQ ON
'Switches on I/Q data acquisition
TRAC:IQ:ONL ON
'Switches the online output of the I/Q data on.
INIT:CONT ON
'Selects continuous measurement data output.
Characteristics: *RST value: OFF
SCPI: device-specific
Mode: A-T
TRACe<1|2>:IQ:SYNChronize[:STATe] ON | OFF
This command switches on or off the synchronization of the start of I/Q data acquisition to the trigger
event. Prior to this command, I/Q data acquisition has to be switched. The synchronization is only
active for sampling rate 32 MHz. It delays the internal trigger event up to 5us to ensure a phase relation
between different I/Q data measurements. This is required for I/Q average.
For I/Q data measurements with exact trigger timing instead, turn off the synchronization. Otherwise,
the R&S FSP produces a trigger jitter of up to 5 µs.
By default, the synchronization is ON.
The I/Q data acquisition is not compatible with other measurement functions.
Therefore all other measurement functions will be switched off as soon as the I/Q
measurement function is switched on. Additionally, a trace display is not possible
in this operating mode. Therefore all traces are set to "BLANK". Finally, split
screen operation will automatically be stopped.
This command is not supported for sampling rates other than 32 MHz.
