Carrier frequency
These commands enable you to set the carrier frequency in the range 9 kHz to 2.4 GHz to a resolution of 1 Hz. You can adjust the frequency in steps by setting the size of the step and then stepping the frequency up or down. After having adjusted the frequency you can either return to the reference frequency or make the current frequency the reference frequency. Additionally, you can adjust the phase offset of the carrier in degrees in the range
CFRQ | Set Carrier Frequency (short form) | |
:VALUE | Set Carrier Frequency | |
:INC | Set Carrier Frequency step size | |
Data type : | Decimal Numeric Program Data | |
Allowed suffices : | Any one of: GHZ, MHZ, KHZ or HZ | |
Default suffix : | HZ |
|
:UP | Go UP one step | |
:DN | Go DOWN one step | |
:RETN | Return to original setting | |
:XFER | Transfer current value to be the new setting | |
Data type : | None |
|
Allowed suffices : | None |
|
Default suffix : | None |
|
:MODE | Selects the mode of carrier frequency operation. SWEPT enables swept | |
| carrier frequency operation, while FIXED disables it | |
Data type : | Character Program Data (FIXED - non swept mode, SWEPT - swept | |
Allowed suffices : | mode) |
|
None |
| |
Default suffix : | None |
|
:START | Set Start Frequency for use in sweep | |
:STOP | Set Stop Frequency for use in sweep | |
Data type : | Decimal Numeric Program Data | |
Allowed suffices : | Any one of: GHZ, MHZ, KHZ or HZ | |
Default suffix : | HZ |
|
:TIME | Set time per sweep step | |
Data type : | Decimal Numeric Program Data | |
Allowed suffices : | MS or S |
|
Default suffix : | MS |
|
:PHASE | Adjust Phase Offset of Carrier in degrees | |
Data type : | Decimal Numeric Program Data | |
Allowed suffices : | DEG |
|
Default suffix : | DEG |

Examples: | CFRQ:VALUE 2.54MHZ;INC 10KHZ | |
| CFRQ:UP;XFER | |
| CFRQ:START 1MHZ;STOP 10MHZ;TIME 100MS | |
| CFRQ:MODE SWEPT | |
CFRQ? | Prepares message containing information on Carrier Frequency setting | |
| in the following format: | |
| :CFRQ:VALUE <nr2>; INC <nr2>;MODE<mode> | |
| where: | <mode> is character program data indicating whether carrier |
|
| frequency operation is swept or fixed |
Example: | :CFRQ:VALUE 1000000000.0;INC 25000.0;MODE FIXED |
