TOne

Default setting: 1000
Parameter: X 1... 4000, frequency in Hz.
Y 1... 4000, frequency in Hz.
Starts the sine wave generator. The frequency required is given as an argument for the
command. The range covers 1 Hz to 4000 Hz with a resolution of 1 Hz. The command
without an argument delivers a tone of 1000 Hz.
The command can also be used to setup a dual tone generator. For this, the second
frequency is entered after the first one, separated by a space. Both tones are generated
simultaneously, which is well suited for measurements of intermodulation distances of
transmitters and power amplifiers.
Example:
aud: TO 1000 2000 <Return>
generates a two-tone signal of 1000 and 2000 Hz the same time.
The amplitude may be set using the FSKAmpl command from the main menu (refer to
chapter 6.42, page 62).
