Example using some of these commands.
SENSe<cnum>:FREQuency:CENTer <num>
(Read-Write) Sets the center frequency of the analyzer. |
|
Parameters |
|
<cnum> |
Any existing channel number. If unspecified, value is set to 1 |
<num> |
Center frequency. Choose any number between the minimum and maximum frequency limits of the analyzer. Units are Hz. This command will accept MIN or MAX instead of a numeric parameter. See SCPI Syntax for more information. |
Examples |
SENS:FREQ:CENT 1000000 sense2:frequency:center 1mhz sense2:frequency:center 1e6 |
Query Syntax |
SENSe<cnum>:FREQuency:CENTer? |
Return Type |
Numeric |
Center of the analyzer's frequency span |
|
SENSe<cnum>:FREQuency[:CW |:FIXed] <num>
(Read-Write) Sets the Continuous Wave (or Fixed) frequency. Must also send SENS:SWEEP:TYPE CW to put the analyzer into CW sweep mode. |
|
Parameters |
|
<cnum> |
Any existing channel number. If unspecified, value is set to 1 |
<num> |
CW frequency. Choose any number between the minimum and maximum frequency limits of the analyzer. Units are Hz. This command will accept MIN or MAX instead of a numeric parameter. See SCPI Syntax for more information. |
Examples |
SENS:FREQ
1000000 |
Query Syntax |
SENSe<cnum>:FREQuency[:CW | :FIXed]? |
Return Type |
Numeric |
1 GHz |
|
SENSe<cnum>:FREQuency:SPAN <num>
(Read-Write) Sets the frequency span of the analyzer. |
|
Parameters |
|
<cnum> |
Any existing channel number. If unspecified, value is set to 1 |
<num> |
Frequency span in Hz. Choose any number from 70 (minimum) and the maximum frequency span of the analyzer. This command will accept MIN or MAX instead of a numeric parameter. See SCPI Syntax for more information. |
Examples |
SENS:FREQ:SPAN
1000000 |
Query Syntax |
SENSe<cnum>:FREQuency:SPAN? |
Return Type |
Numeric |
Maximum frequency span of the analyzer |
|
SENSe<cnum>:FREQuency:STARt <num>
(Read-Write) Sets the start frequency of the analyzer. |
|
Parameters |
|
<cnum> |
Any existing channel number. If unspecified, value is set to 1 |
<num> |
Start frequency. Choose any number between the MIN and MAX frequency limits of the analyzer. Units are Hz. If FREQ:START is set greater than FREQ:STOP, then the stop frequency is set to the start frequency + frequency span. This command will accept MIN or MAX instead of a numeric parameter. See SCPI Syntax for more information. |
Examples |
SENS:FREQ:STAR 1000000 sense2:frequency:start MIN |
Query Syntax |
SENSe<cnum>:FREQuency:STARt? |
Return Type |
Numeric |
Minimum frequency of the analyzer |
|
SENSe<cnum>:FREQuency:STOP <num>
(Read-Write) Sets the stop frequency of the analyzer. |
|
Parameters |
|
<cnum> |
Any existing channel number. If unspecified, value is set to 1 |
<num> |
Stop frequency. Choose any number between 70 (minimum) and maximum frequency limits of the analyzer. Units are Hz. If FREQ:STOP is set less than FREQ:START, then the start frequency is set to the stop frequency - frequency span. This command will accept MIN or MAX instead of a numeric parameter. See SCPI Syntax for more information. |
Examples |
SENS:FREQ:STOP 1000000 sense2:frequency:stop max |
Query Syntax |
SENSe<cnum>:FREQuency:STOP? |
Return Type |
Numeric |
Maximum frequency of the analyzer |
