22. Chopped Mode
a. Performance Check
(1) Turn TI MODE switch to CHOP and oscilloscope (A5) CRT CATHODE
SELECTOR switch (rear panel) to CHOPPED BLANKING.
(2) Adjust time base plug-in (A8) control for a 5-microsecond/division sweep rate on
oscilloscope. Crt will display between 4 and 10 cycles of square wave with vertical portions
b. Adjustments. No adjustments can be made.
23. Gassy Input Amplifier
a. Performance Check
(1) Position TI controls as listed in (a) through (c) below:
(a) CH1 and CH2 VOLTS/DIV switches to .02.
(b) CH1 and CH2 AC-DC-GND switches to GND.
(c) MODE switch to ALTER.
(2) Adjust time base plug-in (A8) controls for 1-millisecond/division horizontal
display on oscilloscope (A5) crt.
(3) Set CH1 AC-DC-GND switch to AC. Oscilloscope display will not shift by more
than 1 minor vertical division.
b. Adjustments. No adjustments can be made.
a. Performance Check
(1) Turn CH1 and CH2 VOLTS/DIV switches to .01 and AC-DC-GND switches to
