HP 83751A User Manual page 163

When one of these keys is pressed, the value of a numeric parameter is
increased or decreased by the step size. (See Table 14-1.) If the active
parameter selections are non-numeric, or discrete selections, such as On/Off,
then the 0) @j keys will scroll through the available selections.
For frequency and power parameters, the value of the step size can be
defined by the user. (See "(EEiGiZ]" .) For other numeric parameters, the
step size is hxed, either as a 1, 2, 5 sequence, or a fixed single step-size. For
the parameters with a 1, 2, 5 sequence, the first press of the key causes the
active parameter to step up or down to a decade multiple of 1, 2, or 5; each
subsequent press steps the active parameter to the next higher or lower
decade multiple of 1, 2, or 5. The table below lists the numeric parameters in
alphabetic order, whether the step size is settable or fixed, and the step size.

down with the arrow keys by whatever amount the frequency step size has been set to using the (STEP)
key. IThis value is 100 MHz at factory preset].
