The variable frequency control for this channel is provided by the algorithm
language. When the algorithm executes an assignment statement to this channel,
the value assigned will be the frequency setting. For example:
O149 = 2000 /* set channel 49 to 2 kHz */
Usage SOUR:PULS:WIDTH 2.50E-3,(@149) set fixed pulse width of 2.5 ms on channel 49
SOURce:PULSe:WIDTh?
SOURce:PULSe:WIDTh? (@<ch_list>) returns the fixed pulse width value on a
frequency modulated pulse channel.
