PWM Source
The MFG-2000 accepts internal and external PWM sources. Internal
is the default source for PWM sources
4. To select the source, press F1
(Internal) or F2 (External).
5. Press Return to return to the
previous menu.
Use the MOD INPUT terminal on
the rear panel when using an
external source.
If an external modulation source is selected, pulse
width modulation is controlled by the ± 5V from
the MOD INPUT terminal on the rear panel. For
example, if duty is set to 100%, then the maximum
duty occurs at +5V, and the minimum duty at -5V.
