Analog-to-Digital Converter
Description
The Analog-to-Digital Ramp Converter is adjusted at zero and
full-scale by injecting a 0 V dc input and + 10 V dc input and adjusting
the OFFS and GAIN controls until the ramp output at A3A8TPll
toggles high to low. This sets the horizontal end points for the CRT
trace display; when the sweep ramp input is at 0 V dc (the left
graticule edge), trace position 1 is set, and when the sweep ramp
input is at + 10 V dc (the right graticule edge), trace position 1000 is
set.
This procedure requires a + 10 V dc source which is stable and
noise-free. A simple supply circuit which can be built with common
components is illustrated in Figure 3-108. If these components are
unavailable, the alternate procedure provided below (using only the
digital voltmeter) can then be used.
