Rubidium™ MG362x1A SeriesLow-Noise RF/Microwave SignalGenerators : Instrument Operation : Pulse Modulation : Setting Pulse SOURCE
 
Setting Pulse SOURCE
Whenever the internal pulse generator is internally triggered, a TTL compatible signal that is synchronized to the internal pulse modulation output is available at the rear panel PULSE SYNC OUT connector.
Press SOURCE to set the source of the modulating signal as Internal or External.
Internal pulse generator provides a 100 MHz clock rate that produces higher resolution pulses and allows higher Pulse Repetition Frequencies (PRFs).
External signals or pulses to trigger or gate the internal pulse generator can be applied to the rear panel PULSE TRIGGER IN connector.
