The waveforms in Figure 6 show the X and Y channel outputs for this program.
The +5 V pulse at A3A3TP12 is the "next X" data from the X DAC. In this program the
"X shift" value from the Expand Register is 0 V. The "present X" value is the waveform of
small spikes every 5 j~s indicate the beginning and end of the 1 /.LS sampling period. A3A3TP4
shows the output of the Sample and Hold circuitry. Note that the output is inverted relative
to the output of the summing amplifier.
