[:SENSe]:FREQuency:CENTer?
Description
Sets the center frequency.
Queries the center frequency.
Parameter
Name
Type
Range
Default
<freq>
Consecutive Real Number
(Smin/2)
[2]
to (Fmax - Smin/2)
Fmax
[1]
/2
Note
[1]
: The maximum frequency Fmax is determined by the instrument model. RSA5000 includes two models: 3.2
GHz and 6.5 GHz.
Note
[2]
: Smin indicates the minimum span in non-zero span.
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?
