5-3 Setup of the monitoring mode
The SDU5600 is designed to provide 3 different monitoring modes such as the spectrum analyser
mode, step resolution mode and channel scope mode. Choosing the most appropriate monitoring
mode for your specific requirements is important to maximise performance and efficiency of the
SDU5600.
Method of selecting each monitoring mode:
Spectrum analyser mode Press FUNC + 1 (SPECT)
Step resolution mode Press FUNC + 2 (STEP)
Channel scope mode Press FUNC + 3 (CHANL)
The 1, 2 and 3 keys are allocated with the ‘second
function’ . The selected mode is displayed on the second
line from the top-right side of the LCD as OP.MODE
Each mode has unique features.
Spectrum analyser mode (SPECT)
This is most suited for general listening and to hunt for non specific signals or noise,
by sweeping across the defined range of spectrum (up to a bandwidth of 10MHz).
Step resolution mode (StepReso)
This is most suited to monitor specific signals across a known relatively wide defined
band where signals are allocated with a certain stepping size, for example VHF
airband. The horizontal x-axis of the LCD has a resolution of 320 dots, each dot
represents one step, so there are a total of 320 steps.
Channel scope mode (Channel)
This is most suited to monitor a
known narrow channelised band of
frequencies such as the VHF or UHF
amateur band. Channel scope mode
can emulate almost a real-time band
scope between the start and end
frequency with defined stepping size.
When the companion
receiver has been selected
as
Other the channel scope
mode is disabled.
