7. Equipment Setup
WARNING
HIGH VOLTAGE is used or exposed during the performance of
this calibration.
DEATH ON CONTACT may result if
personnel fail to observe safety precautions.
REDUCE
OUTPUT(S) to minimum after each step within the
performance check where applicable.
a. Set 115/230 switch (rear panel) to 115.
b. Connect TI to autotransformer.
c. Connect autotransformer to a 115 V ac source and adjust for a 115 V output.
d. Position controls as listed in (1) through (8) below:
(1) REPETITION RATE switch to 10 kHz and vernier control fully cw.
(2) DELAY/ADVANCE switch to 1 s and vernier control fully ccw.
(3) WIDTH switch to 1 s and vernier control fully ccw.
(4) AMPLITUDE VOLTS switch to 2 V and vernier control fully cw.
(5) GATE MODE switch to NON-GATED.
(6) PULSE MODE control to DELAY.
(7) SYNC POLARITY switch to POS.
(8) PULSE POLARITY switch to NEG.
e. Set POWER switch to ON and allow at least 30 minutes for equipment to warm-up
and stabilize.
8. Repetition Rate
a. Performance Check
(1) Connect PULSE OUTPUT to frequency counter.
NOTE
.
Set frequency counter input impedance to 50
(2) Measure repetition rate. Frequency counter will indicate 10 kHz or greater.
(3) Repeat technique in (2) above, using settings listed in table 4.
Frequency
counter will indicate within limits specified.
b. Adjustments. No adjustments can be made.
