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

(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
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.
