10-13 [:SENSe] Subsystem
[:SENSe]:FREQuency:COUPling OFF|ON|0|1
[:SENSe]:FREQuency:COUPling?
Description: Turns on frequency coupling. When frequency coupling is on, the
Cmd Parameters: OFF|ON|0|1
Query Parameters: NA
Range: OFF|ON|0|1
Default Value: OFF
Default Unit: NA
Example: To turn Rx/Tx frequency coupling on:
Front Panel Access: Frequency, Rx/Tx Coupling
[:SENSe]:FREQuency:COUPling:OFFSet <value>
[:SENSe]:FREQuency:COUPling:OFFSet?
Description: Sets the frequency coupling offset. If frequency coupling is on, the
Cmd Parameters: <Value>
Query Parameters: NA
Range: -1000000000 Hz to 1000000000 Hz
Default Value: 0 Hz
Default Unit: Hz
Example: To set coupling offset to 200 MHz:
Front Panel Access: Frequency, Coupling Offset
10-40
Tx frequency cannot be set directly. The Rx Frequency and coupling
offset must be used to set the desired Tx frequency. The Tx frequency
will automatically trail the Rx frequency by the frequency coupling
offset every time the Rx frequency is set. Please note that turning on
frequency coupling will automatically move the Tx frequency to the
Rx frequency plus any frequency coupling offset. If the Rx frequency
and frequency coupling offset is at a setting where the Tx frequency will
be beyond the min/max limits, the instrument will not allow coupling to
be turned on. The query command returns the state of the frequency
coupling setting. A return value of 1 is ON, and a return value of 0 is
OFF.
:SENSe:FREQuency:COUPling ON
Tx frequency will automatically trail the Rx frequency by this amount.
Please note that the instrument will prevent any coupling offset setting
that will make the Tx frequency go beyond the min/max values.
The query returns the current coupling offset in Hz.
