1820/1822 Operator’s Manual
.
hh. Remove all cables and connections from the
i 820/1822.
Check the Precision Voltage Generator
Accuracy (1822 Only).
a. Connect a BNC cable from the OFFSET
VOLTAGE output connector on the rear
panel to a DMM without a 50 f2 termination.
b. Push the PVG ZERO button.
c. Set the DMM to DC Volts on the most
sensitive range. After the display has
stabilized record the reading as ’PVG Zero
Output Voltage’ in the Test Record.
d.
CHECK -- That the measured 0.0000 V
output is within + 0.5 mV of zero.
e.
Set the DMM range to read 15.5 V.
f. Press and hold MSB increment button (button
to right of
+
button) until the display reads
+15.000 V. If necessary, press the + button
once to invert the polarity.
g. After the DMM display has stabilized record
the reading as ’PVG Output Voltage at + 15.5
V’ in the Test Record with 100 p.V resolution
h. CHECK-- That the measured output is
within15.4917 to 15.5082 V.
i. Press the + button to change the output
voltage to -15.5000 V.
j. After the DMM display has stabilized record
the reading as ’PVG Output Voltage at -15.5
V’ in the Test Record to 100 ~tV resolution.
k.
CHECK-- That the measured output is
within -15.4917 to -15.5082 V.
!.
Disconnect DMM and all cables from
amplifier.
This completes the Performance Verification Procedure.
File the test results as required to support your internal
calibration procedures.
