Spectrum Analyzer Mode Key Descriptions
Spectrum Analyzer Mode Functions
ANALOG+
ON
OFF
turns on the analog+ display mode. This is a digital
implementation of an analog display, combining the
advantages of both types of displays. The display is made up
of 401 horizontal points or trace elements. In the analog+
display mode each trace element can display from 1 to 40
dots, or measurements.
Pressing ANALOG+ ON OFF makes dot density the active
function. The dot density function sets the desired number
of measurements per trace element. Each dot requires
an additional analog-to-digital conversion for each trace
element, so the sweep time can limit the actual number of
dots available. Lengthening the sweep time can increase the
actual dot density.
Markers and marker functions as well as the screen text and
title capabilities of a digital display are available along with
the analog type trace information. Some functions are not
available with analog + display mode. See Table
6-
1 for a list
of functions that are not available with analog+ displays. If
a trace is blanked while using an analog+ display, the data
is permanently blanked and cannot be recalled, even if you
use the view function.
The copy function can be used to provide a printout of the
display. It must be configured to use a printer and not a
plotter. After using other functions, press ANALOG+ ON OFF
to return to the dot density function.
Limit lines can be used to test data in an analog+ display,
but they cannot be displayed.
