Entry Keys
When this key is pressed, the value of the frequency or power step size
becomes the active parameter and is shown in the MARKER/SWEEP/STATUS
display. Frequency or power is displayed depending on whether a key in the
FREQUENCY or the POWER area was last pressed. If the active parameter is
not a frequency or power parameter, the display will read:
S i z e * * .
The display format is
both the type and magnitude of the step. For frequency step size, the possible
units are Hz, kHz, MHz, and GHz. For power step size the only possible unit
is dl3. If the 0) @J keys are used while step size is the active parameter, the
step size will be increased or decreased in a 1, 2, 5 sequence.
