Stop Freq
sets the frequency at the right side of the graticule. The left and
right sides of the graticule correspond to the start and stop
frequencies.
Key access: Frequency > Stop Freq
CF Step
changes the step size for the center frequency function. On
Auto Man
selecting a step size and activating the center frequency function,
the arrow keys change center the frequency by the step-size value.
The step size function is useful for finding harmonics and
sidebands beyond the current frequency span of the analyzer.
Selecting auto-couple sets the center frequency step size to one
division (10 percent of the span).

The Channel Standard softkey is a shortcut to loada factory-preset
standard file (*.STD) which is located in system memory as default.
The standard file list includes most communication protocol
standards which is used in several countries. Please refer to
"Loading a file" on page 72 for how to recall a file.
Key access: Frequency > Channel Std.
Freq Offset
inputs a frequency offset value added to the frequency readout of
the marker, to account for frequency co versions external to the
analyzer. Offset entries are added to all frequency readouts
including marker, start frequency, and stop frequency. Offsets may
only be entered using the numeric keypad. Offsets are not added to
the span or frequency count readouts. Entering an offset does not
affect the trace display. When a frequency offset is entered, its
value appears on the bottom of the display. To eliminate an offset,
perform a Factory Preset, or press Freq Offset, 0, Hz.
When a frequency offset is entered, its value appears on the
bottom of the display (as opposed to reference level offsets, which
appear on the left side of the display). To eliminate an offset, press
Freq Offset, 0, and Enter. Pressing Preset also sets the offset to zero.
