The Step Size display allows static parameters to be incremented or
decremented by a selectable delta.

Press the Step Size key once to invoke the step menu.
Press the desired parameter field to highlight the parameter. Use the
keypad to enter a numeric value (valid ranges and resolutions are same
as the corresponding parameter).
Press the appropriate units key to enter.
Press the Return key to return to the main display.
A unique step size is saved for each parameter type, and each parameter
step size can be unique for each channel.
Note that if the entered step size exceeds the realizable limit, the value
will be set to the valid limit.
The following step sizes may be defined
Delay
Attenuation
Frequency Offset
Phase Offset

A threshold value can be entered to define whether delay changes are
implemented as a linear slew or as an instantaneous step. A change in
delay that is less than the threshold will be implemented via slewing. A
change in delay that is greater than the threshold will be implemented
in a single step. Delay slewing prevents phase discontinuities in the
output signal. The delay slew rate is fixed at 2 msec/sec. The Delay
