General Dynamics R2600 Series User Manual

3-7.2.3 EXT'L SCOPE
The analyzer provides a general purpose oscillo-
scope with calibrated vertical input sensitivities
and automatic or triggered horizontal sweep
rates. Use the scope to analyze waveforms, detect
asymmetric modulation or audio distortion, trace
signals, and troubleshoot.
The vertical (VERT) input is the same BNC port
that also serves as the input for DVM,
SINAD/DIST meter, and COUNTER IN.
The EXT'L SCOPE mode has an additional
cursor field to select "Coupling:" AC or DC via
softkey selection. Operation of triggering,
ranges, trace positioning and optional markers are
the same as described in MODULATION
SCOPE above. Vertical ranges will always
display in voltage per division in the EXT'L
SCOPE mode.
3-7.2.4 SWEEP GENERATE
This display provides a graphic display in con-
junction with the SW
EEP GENERATE mode of
the unit which is selected in the RF Control zone
or selection of the optional cable fault test
feature.
Refer to Sweep Generator description under
Primary Operating Modes (paragraph 3-5.4).
To change coupling from AC to DC, or vary
horizontal position, vertical position, or vertical
sensitivity, move the cursor to highlight that
selection. Use the softkeys or TUNING knob, as
applicable to each selection.
3-7.2.5 Bar Graphs
The bar graphs (figure 3-22) provide a graphical
display of the RF Display data from the Meter
area of the screen.
Press the expand softkey to expand the bar graphs
to the full display area of the LCD (figure 3-22).
If the modulation type is FM, the BAR GRAPHS
mode has an additional cursor field to select “Dev
Avg:” PEAK AVERG, RMS AVERG or NORM
via softkey selection. The setting activates either
the Peak averaging or RMS meter or normal peak
detection on the deviation measurements. The
PEAK AVERG computes a numerical average of
peak detection measurements, the RMS AVERG
uses a RMS meter to compute the deviation, the
NORM use a instaneous peak detection
measurement. Note the “Dev Avg:” cursor is not
available in modulation types, AM or PM.
