Input D AC Voltage Accuracy (HF) and Bandwidth Test
Note
The test steps for channel C are only for the models 190-104,
190-204, and 190-504.
Proceed as follows to test the Input D high frequency automatic scope ac voltage
measurement accuracy and the bandwidth:
1. Connect the Test Tool to the 5502A as shown in Figure 4-10.
2. Recall the setup (see Standard Test Tool Setup) to select the Test Tool
setup.
3. Press
SAVE
,
F2
(RECALL) and select SETUP, press
ENTER
, select the
setup name, and press
ENTER
to recall the setup.
4. Press
SCOPE
, then press
F2
(READING…), and select READINGS 4 on D
| V ac
.
5. Press
MANUAL
AUTO
to select autoranging (AUTO in upper right LCD edge).
6. Use
mV
RANGE
and
V
RANGE
to change the sensitivity range to select manual
sensitivity ranging and lock the Input D sensitivity range on 500 mV/div.
7. Use
MOVE
to move the Input D trace zero to the center grid line.
8. Press
TRIGGER
and use
F1
to select Input D as trigger source.
9. Set the 5502A to source a sine wave and to the first test point in Table 4-16.
10. Observe the Input D reading and check that it is within the range shown
under the appropriate column of Table 4-16.
11. Continue through the test points.
12. When you are finished, set the 5502A to Standby.
