External Reference Frequency
Determines the frequency of the external reference signal.
You can select an external reference signal having a frequency of 5 MHz or 10 MHz.
Note: The installed hardware determines the available settings. Use the Hardware
Config dialog to check the hardware the instrument is equipped with.
For information on the required hardware revision, refer to the release notes.
Remote command:
[:SOURce]:ROSCillator:EXTernal:FREQuency

Synchronization Bandwidth
Selects the synchronization bandwidth for an external reference signal.
"Narrow" Synchronization bandwidth is 50 Hz.
"Wide" The synchronization bandwidth is approximately 350 Hz.
This mode is useful for very precise reference sources of high spec-
tral purity.
Remote command:
[:SOURce]:ROSCillator:EXTernal:SBANdwidth

Adjustment Active
Selects the adjustment mode.
"OFF" Uses the calibrated internal reference frequency.
"ON" Allows you to apply a deviation to the internal reference frequency,
according to your requirements. To enter the value, use
Adjustment
DAC Value .
Remote command:
[:SOURce]:ROSCillator[:INTernal]:ADJust[:STATe]
on page 407
Adjustment DAC Value
Sets a user-defined deviation for the internal reference frequency. This value takes
effect when it is activated with
Adjustment Active . "0" represents the calibrated state.
The setting range depends on the reference oscillator type and its factory calibration
value.
Note: A factory preset resets this setting to the calibration value of the instrument.
