1-6 OSCILLOSCOPE
The COM-120C has a 50 kHz single trace Oscilloscope. The Oscilloscope can operate
as a dependent or independent function in each of the Operation Modes. Both functions
give the choice of operation modes, live, store, recall, compare and average. The
Trigger type choices are Normalized, Auto and One Shot.
Dependent
The dependent Oscilloscope is available with meters and shares space in all Operation
Modes with the dependent Spectrum Analyzer. In Generate Operation, sources
available for the Oscilloscope are through front panel input connectors, Notch Filter
Residual and internal modulation sources. In Receive Operation, sources available for
the Oscilloscope are through the front panel input connectors, Audio/Data/Signaling
Generators, decode lines, meter lines and the demodulated signal, both filtered and
unfiltered. Sweep and scale values differ with each input type.
Independent
The independent Oscilloscope only accepts signals from the SCOPE/DVM Connector.
The coupling choices are AC, DC and Ground.
