High-Pass Filter is used to define the cutoff frequency of a high-pass filter. The
range is from 0.1 Hz to current frequency range.
Label is used to change the name of the signal. Use the alphanumeric keypad to
enter a label name and press the OK soft button to accept it.
Param -> Output Channel is used to define the waveform for the output
channel. Use the Up/Down arrow buttons to select from Sine, Triangle, Square,
White Noise, Pink Noise, DC, Chirp, Swept Sine or Arbitrary Signal. Selecting
None turns off the output channel. When a signal type has been selected,
pressing Right will shift the selection cursor to set the parameters for that type of
output.

For each waveform the parameter settings must also be enters such as range,
frequency and amplitude. Output Channel is a global setting that applies any
loaded CSA. Once the parameters have been set, the output must be turned on by
pressing F4 (Enable). The output can be turned off by pressing F4 (Disable).
When the Arb waveform is selected, an arbitrary waveform file must be
selected to output. This file must be uploaded to the CoCo-80 through EDM
before it can be used.
