Activates a display line that can be adjusted with the
data keys, the step keys, or the knob. When the display
line is ON, pressing DSPL LIN ON OFF again turns
the display line OFF.
Front-panel key access:
Selects the polarity for edge triggering of a gated
measurement. The gate can be triggered on either a
positive or negative going edge of the rear panel input
EXT/GATE TRIG INPUT.
Front-panel key access:
Accesses a menu of functions for editing the
frequency-amplitude pairs which define the desired
measurement correction. The SCROLL CORR PTS
softkey is automatically activated and highlighted upon
entering the new menu. Current correction data is
displayed. The knob and the step-keys can be used to
scroll through the correction points.
If correction data is available when the edit ampcor
function is activated, amplitude correction is turned on,
the correction is applied to the displayed trace, and the
data is available for editing. If there are no current
correction points, the function is not turned on until
you have entered a point.
Each correction point consists of a frequency at which
the correction should be applied, and the amplitude of
the correction in decibels. The spectrum analyzer
accepts, stores and corrects frequencies with 1 Hertz
resolution. The amplitude resolution is in hundredths
of a dB, although the displayed resolution may be less.
The list of correction points is sorted in order by
frequency.
Front-panel key access:
Allows you to modify the amplitude information
associated with the currently selected correction point.
After pressing this softkey, the amplitude can be edited
using the knob, step-keys, or numeric keypad.
