Frequency and Amplitude
Frequency and Amplitude
The knob and reference set keys work similarly for both frequency and amplitude settings.
1. Knob
Turn the knobs to increment or decrement the frequency and amplitude settings. The
knobs are always active when the instrument is in local operation.
If Option 1EP is present and the signal generator is in the ENCODER mode, the knob in
the AMPLITUDE/ENCODER block is used to select the desired setting for each pager
encoder parameter.
2. Digit-Select Arrow Keys
Press these digit-select arrow keys (⇐ ⇒)to select the digit to be changed with the knob.
NOTE The knobs increment the selected digit only. For information about
incrementing by an arbitrary value using the increment set keys, see
“Increment Set” in this chapter.
3. REF SET
Press REF SET to turn on the reference mode and to set the current RF output setting as
the reference value. The reference value is stored in non-volatile memory until you replace
it by pressing
REF SET again.
When you press
REF SET, the ∆ symbol is displayed between the value and the units. When
∆ appears, the displayed value indicates the offset between the reference value and the RF
output signal.
