An analog vector generator on the other hand will
recharge a high
quality capacitor (often compensated). Once the X and Y axis DACS
have charged these caps to the vector starting point voltages, the DAC's
are updated with the vector end-point values an analog switching then
causes the caps to charge or discharge to the new values.
It seems to me there were some analog vector systems that could do smooth
curves as well. Complete engineering overkill.
