7-29. PROGRAMMABLE DIGITIZER 2A2A1
7-29
INPUT CODE: DIGITST
a .
DESCRIPTION
This module tests the ability of programmable digitizer assembly 2A2A1 to accept
stimulus inputs and convert them to digital equivalents.
If an error is detected in the following checks, a prompt is displayed at the
completion of the test.
The programmable amplifier channel A is programmed to 1 V/D, POS -4 and coupling
to ground.
The data is sampled, moved to a matrix, and averaged. The averaged
sampled data is checked for O to 15.
Channel A is programmed to 1 V/D, POS -2 and coupling to ground.
The data is sampled, moved to a matrix, and averaged, The averaged sampled data
is checked for 52 to 76.
Channel A is programmed to 1 V/D, POS 0, and coupling to ground. The data is
sampled, moved to a matrix, and averaged.
The averaged sampled data is checked for
118 to 128.
Channel A is programmed to 1 V/D, POS +2, and coupling to ground. The data is
sampled, moved to a matrix, and averaged.
The averaged sampled data is checked for
180 to 204.
Channel A is programmed to 1 V/D, POS +4, and coupling to ground. The data is
sampled, moved to a matrix, and averaged.
The averaged sampled data is checked for
240 to 255.
The programmable amplifier channel B is programmed for 1 V/D, POS -4, and
coupling to ground.
The data is sampled, moved to a matrix, and averaged. The
averaged sampled data is checked for O to 15.
Channel B is programmed for 1 V/D, POS -2, and coupling to ground. The data is
sampled, moved to a matrix, and averaged.
The averaged sampled data is checked for
52 to 76.
Channel B is programmed for 1 V/D, POS O, and coupling to ground. The data is
sampled, moved to a matrix, and averaged.
The averaged sampled data is checked for
118 to 128.
Channel B is programmed to 1 V/D, POS +2, and coupling to ground. The data is
sampled, moved to a matrix and averaged.
