:SENSe:FREQuency:SPAN:FULL
:SENSe:FREQuency:STARt
:SENSe:FREQuency:STOP
Command
Sets the frequency span, i.e. the measured bandwidth, in Hertz. A new fre-
quency span setting will leave the center frequency unchanged but affect
start and stop frequencies; only if the new start or stop frequency exceeds
a limit of the 9102, the center frequency will be changed accordingly.
Query
Reads and returns the current setting.
Example
:SENSe:FREQuency:SPAN 1500000000
:SENSe:FREQuency:SPAN?
The value returned in this example is: "1500000000".
Syntax
:SENSe:FREQuency:SPAN:FULL
Parameters
There are no parameters.
Command
Sets the 9102 to the maximum supported frequency span. This command
affects start, stop and corresponding center frequency.
Note: If you set the span to 0, the 9102 will perform measurements in the
time rather than the frequency domain.
Query
There is no query form of this command available.
Example
:SENS:FREQ:SPAN:FULL
Sets the start frequency of the 9102 to 0 and the stop frequency to 4 GHz
(or 7.5 GHz if the frequency extension option is installed).
Syntax
:SENSe:FREQuency:STARt <real1>
Parameters
real1 is a floating point real number.
The minimum value for real1 is 0, the maximum value
7500000000. The
minimum resolution possible for real1 is 1000. The default value for
real1 is 0.
Command
Sets the start frequency of the 9102, in Hertz. This command leaves the
span as is but affects the center frequency and the stop frequency.
Query
Reads and returns the current setting.
Example
:SENSe:FREQuency:STARt 1500000000
:SENSe:FREQuency:STARt?
The value returned in this example is: "1500000000".
Syntax
:SENSe:FREQuency:STOP <real1>
Parameters
real1 is a floating point real number.
The minimum value for real1 is 10000, the maximum value
7500000000.
The minimum resolution possible for real1 is 1000. The default value for
real1 is 3600000000.
Command
Sets the stop frequency of the measured bandwidth, in Hertz. This com-
mand leaves the span unchanged but affects the center frequency and the
start frequency.
Query
Reads and returns the current setting.
