Input A AC Voltage Accuracy (HF) and Bandwidth Test
Proceed as follows to test the Input A high frequency automatic scope ac voltage
measurement accuracy and the bandwidth:
1. Connect the Test Tool to the 5502A as shown in Figure 4-6.
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

on
A | V ac
.
c) Press
MANUAL
AUTO
to select autoranging (
AUTO
in upper right LCD edge).
d) Use
mV
RANGE
and
V
RANGE
to change the sensitivity range to select manual
sensitivity ranging, and lock the Input A sensitivity range on 500 mV/div.
AUTO
in upper right LCD edge becomes
½ AUTO
.
e) Use
MOVE
to move the Input A trace zero to the center grid line.
3. Set the 5502A to source a sine wave and to the first test point in Table 4-10.
4. Observe the Input A reading and check that it is within the range shown
under the appropriate column.
5. Continue through the test points.
6. When you are finished, set the 5502A to Standby.
