Fig. 5-2. (A) Location of -12-volt and + 12-volt power supply test
points (left side of indicator), (B) location of DC power supply
adjustments (DC Power Control board).
f. CHECK—Test oscilloscope display similar to Fig.
5-3C. If necessary, readjust the test oscilloscope triggering
control so the display starts at the correct point.
g. ADJUST—Oscillator Frequency adjustment R 1125
(see Fig. 5-2B) fo r waveform similar to that shown in Fig.
5-3C w ith a minimum amount of jitter.
h. Recheck step 1. If readjustment is necessary, recheck
this step also.
i. Disconnect the precision DC voltmeter and the test
oscilloscope.
3. Check DC Regulation
a. Set the variable DC power supply fo r + 1 1.5-volts
output.
b. CHECK—Table 5-1 lists the power supplies in this
instrument. Check each supply w ith the precision DC
voltmeter fo r output voltage w ithin the given range. Power
supply test points are shown in Figs. 5-2 and 5-4.
