(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 |
|
|
(Read-Write) Sets and reads how the center frequency step size is set. When TRUE, center steps by 5% of span. When FALSE, center steps by STEP:SIZE value. |
|
|
Parameters |
|
|
<cnum> |
Any existing channel number. If unspecified, value is set to 1 |
|
<bool> |
Choose from: ON (or 1) - Step size is set automatically. OFF (or 0) - Step size is set manually using SENS:FREQ:CENT:STEP:SIZE |
|
Examples |
SENS:FREQ:CENT:STEP:AUTO 1 |
|
Query Syntax |
SENSe<cnum>:FREQuency:CENTer:STEP:AUTO? |
|
Return Type |
Boolean |
|
OFF |
|
|
(Read-Write) Sets the center frequency step size of the analyzer. This command sets the manual step size (only valid when STEP:AUTO is FALSE). |
|
|
Parameters |
|
|
<cnum> |
Any existing channel number. If unspecified, value is set to 1 |
|
<num> |
Step size in Hz. Choose a value below the stop frequency of the analyzer. |
|
Examples |
SENS:FREQ:CENT:STEP:SIZE 1e9 |
|
Query Syntax |
SENSe<cnum>:FREQuency:CENTer:STEP:SIZE? |
|
Return Type |
Numeric |
|
Default is 40 MHz. When STEP:AUTO is TRUE, this value is ignored. |
|
|
(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 |
|
|
(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 |
|
|
(Write-Only) Sets the frequency span to the entire frequency range of the analyzer. |
|
|
Parameters |
|
|
<cnum> |
Any existing channel number. If unspecified, value is set to 1 |
|
Examples |
SENS:FREQ:SPAN:FULL |
|
Query Syntax |
Not Applicable |
|
Maximum frequency span of the analyzer |
|
|
(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 |
|
|
(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 |

SENSe<cnum>:FREQuency:STOP? |
|
Return Type |
Numeric |
|
