MODULATION MODES    
     
Sweep    
Linear or logarithmic sweep is provided for both standard and arbitrary waveforms. Frequency span can be from 1mHz to 40 MHz in one range, phase continuous, with independent setting of start and stop frequency. The sweep time is variable between 1ms and 999 seconds and there is a variable sweep marker. The sweep may be free run or triggered manually from the card or externally from the trigger input or remote interface AM or SCM modulation using the external signal input
     
Burst, Gated and Tone Switching    
Standard and arbitrary waveforms can be used in Triggered Burst, Gated or Tone Switching modes. The trigger source can be internal from keyboard trigger generator, or external from TRIG IN or remote interface. For tone switching, a list of up to 16 frequencies from 1mHz to 40MHz can be generated with instantaneous switching between them.
    
Trigger Generator
