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

Default

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
SENS:FREQ:CW MIN
sense2:frequency:fixed 1mhz

Query Syntax

SENSe<cnum>:FREQuency[:CW | :FIXed]?

Return Type

Numeric

Default

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
sense2:frequency:span max

Query Syntax

SENSe<cnum>:FREQuency:SPAN?

Return Type

Numeric

Default

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

Default

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

Default

Maximum frequency of the analyzer
