MANUAL TEST (Synchronous Mode)
Measuring: Spectrum Monitor
The RF spectrum of the traffic channel can be measured with Spectrum Monitor.
When aborted, the span from 0 Hz to +400 kHz relative to the traffic channel
frequency is shown with the readouts at +200 kHz (M1) and +250 kHz (M2)
offsets. The actual measured amplitudes at those frequencies are shown in enlarged
numerals.
