Generator Controls
The A and B On/Off buttons turn the A and B channels of signal
generation on and off. The yellow lights for each channel indicate
whether that channel is providing output. Ifthe light is on, then the
channel is enabled. The On/Off function affects the internal
generator-monitor path as well as the external generator outputs.
The MUTE key will immediately disconnect both channels ofoutput.
A second press ofthe MUTE key will turn on any channels ofoutput
that were turned on before MUTE was initially pressed.
In most cases, the Amplitude controls will control the amplitude ofboth
channels ofthe analog output signal and the Frequency controls will
control the frequency ofboth channels ofthe analog output signal. In
some analyzer situations, other parameters may be connected to these
knobs when viewing the Main Panel. However, the knobs always
control the generator amplitude and frequency when you are viewing
the Generator Only panel. The generator operates no matter which
panel you are viewing.
The generator section ofthe panel on the Main Panel or Generator
Only Panel will display the current amplitude, frequency, and
waveform shape.
The waveform shape is controlled by the upper left soft key on the
Generator Only panel. Waveform shapes of sine, square, and IMD (if
IMD option is installed) are available with subsequent presses ofthe
soft key.
