Operation
STEP, iNCREMENT SET
The values of Signal Generator functions can be stepped up or down by an increment
set value using the Step keys ( OJ or CO ).
The Signal Generator powers up with default increment set values for all functions
that allow increment set. (Refer to Table 3-26 below.) You can select a desired
increment set value up to the listed maximum. The Signal Generator returns to
default increment values if the Power is switched from standby to on or if Instrument
Preset is selected.
You can also use the Step keys in the following ways:
G When saving or recalling successive registers. (Refer to Save/Recall, page 3 -157.)
• When stepping through the Help listing. (Refer to Special Functions, page 3 -16 7.)
• When incrementing the phase of the RF frequency using Special Function 250.
(Refer to RF Frequency, page 3-42.)

Select a function, then select ( INcR SET J, the desired increment set value, and an
appropria te units key
How to Increment a Function
Select the desired function key. Each time you press a Step key, the function's value
changes by one step. The Step keys repeat when held down.
If no increment set value has been selected, the Step keys use the default increment
set value to change the value of the active function.
