CW Signal Generator Mode (Option 28)
To select CW Signal Generator mode, press the MODE key and use the down arrow to
highlight
CW Signal Generator and press ENTER.
The CW Signal Generator option provides a CW signal from the instrument. The primary
purpose of this signal is for sensitivity testing of receivers. To use this feature, the signal is
connected directly to the receiver being measured and the output amplitude is reduced until
the receiver drops the signal.
The external splitter feeds the signal into the instrument's RF input. The display shows the
output power and frequency. The amplitude is set using an external step attenuator.
The external splitter and attenuator are customer-supplied.
