Input A, B, C, D Peak Measurements Test
Warning
To prevent possible electrical shock, fire, or personal injury,
ensure that the calibrator is in standby mode before making any
connection between the calibrator and the Test Tool.
Dangerous voltages are present on the calibration source and
connection cables during these steps.
Note
The test steps for channel C and D are only for the models
190-104, 190-204, and 190-504.
To test the peak measurement accuracy:
1. Connect the Test Tool to the 5502A as shown Figure 4-4.
2. Select the Test Tool setup:
a) Recall the setup (see Standard Test Tool Setup). Press
SAVE
,
F2
(RECALL) and select SETUP, press
ENTER
, select the setup name, and
press
ENTER
to recall the setup.
b) Press
SCOPE
.
c) Press
F2
(– READING …) and select with
F1
(– READINGS)
and with
:
Reading 1, on A, Peak … and next Peak-Peak
Reading 2, on B, Peak … and next Peak-Peak
Reading 3, on C, Peak … and next Peak-Peak
Reading 4, on D, Peak … and next Peak-Peak
d) Press
CLEAR
to clear the softkey menu, and to see the full display.
3. Use
TIMEsns
to change the time base and lock the time base on 1 ms/div.
4. Use
mV
RANGE
and
RANGE
to set the Input A, B, C, and D sensitivity ranges to
100 mV.
5. Set the 5502A to source the appropriate ac voltage and frequency as listed in
Table 4-6.
6. Observe readings
A, B, C, and D and check that they are within the range
shown under the appropriate column.
7. When you are finished, set the 5502A to 0 (zero) Volt and Standby.
