RIGOL Chapter 2 Command Systems for GPSA and RTSA Modes
2-144 RSA3000E Programming Guide
Remarks
This command is only available for RTSA mode.
[:SENSe]:INITiate:FCAPture
Syntax
[:SENSe]:INITiate:FCAPture
Description
Initiates the IQ capture.
Remarks
This command is only available for RTSA mode.
[:SENSe]:FREQuency:CENTer
Syntax
[:SENSe]:FREQuency:CENTer <freq>
[:SENSe]:FREQuency:CENTer?
Description
Sets the center frequency.
Queries the center frequency.
Parameter
Name
Type
Range
Default
<freq>
Consecutive Real
Number
GPSA mode
0 Hz to Fmax
[1]
(zero span)
5 Hz to (Fmax - 5 Hz) (non-zero span)
Fmax/2
RTSA mode
2.5 kHz to (Fmax - 2.5 kHz)
Note
[1]
: Fmax (maximum measurement frequency) is determined by the model of the spectrum analyzer. The
maximum frequency of RSA3030E/RSA3030E-TG is 3 GHz, and the maximum frequency of RSA3015E/RSA3015E-TG is
1.5 GHz.
Return Format
The query returns the center frequency in scientific notation. The unit is Hz.
Example
The following command sets the center frequency to 1 MHz.
:SENSe:FREQuency:CENTer 1000000
The following query returns 1.000000000e+06.
:SENSe:FREQuency:CENTer?
