R&S ESU Remote Control – Description of Commands
TRACe Subsystem
6.258 Operating Manual 1302.6163.12 - 03
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:FILTer:FLATness NORMal | WIDE
This command allows measurement with extended usable signal bandwidth for sample rates in the
range of either 10.2 MHz to 20.4 MHz or 20.4 MHz to 40.8 MHz.
Example: "TRAC:IQ:FILT:FLAT WIDE"
Characteristics: *RST value: NORM
SCPI: device-specific
Mode: A
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.
NORMal Normal operation
WIDE Extanded usable signal bandwidth, reduced selectivity
Sample Range Usable Bandwidth
NORMAL WIDE
10.2 MHz < Sample Rate <= 20.4 MHz 0.8 * Sample Rate 0.9 * Sample Rate
20.4 MHz < Sample Rate <= 40.8 MHz 0.68 * Sample Rate 0.8 * Sample Rate
