EXT REF INPUT. This input is used when synchronizing multiple arbitrary/function
generators or an arbitrary/function generator and another device.
EXT REF OUTPUT. This output is used when synchronizing multiple arbitrary/func-
tion generators or an arbitrary/function generator and another device.
ADD INPUT. (Dual-channel model only) Additional Input connector allows you to
input a signal from some other source and add that signal to CH 1 output.
EXT MODULATION CH 1 INPUT. A signal applied to the External Modulation CH 1
Input connector is used to modulate the CH 1 output signal. The signal input level
applied to this connector will control the modulation depth.
EXT MODULATION CH 2 INPUT. (Dual-channel model only) The External Modula-
tion CH 2 Input connector is used to apply an external modulating signal to the CH
2 output signal. The signal input level applied to this connector will control the
modulation depth.
