System frame period Waveform pattern output Additional Processing delay delay Fig. 2.6.2-4 Start Trigger operation Notes: 1. If Delay is set to 0, some delay is internally added to the processing delay that is generated during the period from trigger input to output of the waveform pattern (additional delay), and the signal is output one frame period late.
Page 76 Chapter 2 Operation (Signal Generator Function) Frame Trigger Operation The Frame Trigger operation outputs one burst of the waveform pattern with the rising timing of the external trigger signal. The relationship between the external trigger signal and the waveform pattern output is the same as Start Trigger.
Page 77 Setting External I/O For example, suppose that L = 140 symbols, L = 280 symbols, and the sampling clock = 50 MHz. In this case, because the right-hand side of the N formula above exceeds N , N = 28. In Fig. 2.6.2-6, if a trigger signal is input with a period 28 samples shorter than the frame period (L ), it will be disabled.
