7 Analog Modules Waveform Generators

194 System Reference, January 2001

Attenuator

The attenuator adjusts the amplitude of the signal gener-

ated by the digital-to-analog converter.

Filter

The filter is a low pass filter for smoothing the waveforms.

This filter removes harmonics from the signal. There are

several filters with different cut-off frequencies.

Digital-to-Analog Converter

The digital-to-analog converter (DAC) converts the digital

waveform data transferred the waveform memory to the

analog signal, according to the output sequence from the

sequencer. The DAC converts the digital data to the analog

signal according to the conversion clock provided by the

timing generator.

Timing Generator

The master clock and trigger signal are input to the timing

generator. After receiving the trigger signal, the timing

generator starts to generate the conversion clock by

dividing the master clock and feeds the conversion clock

to the DAC. The timing generator also sends the start

signal to the sequencer. The timing generator stops to

generate the conversion clock when the sequencer is

halted.

The timing generator contains the delay counter and delay

vernier. By using them, the timing generator controls the

delay time from when the trigger signal arrives at the

trigger input pin to when waveform generation starts at

the pogo pin.
