Note
Because Duty Cycle and Pulse Width measurements are
based on the same principles as Frequency measurements,
these measurement functions will not be verified separately.
Input A&B / C&D Phase Measurements Test
Note
The test steps for channel C and D are only for the models
190-104, 190-204, and 190-504.
Proceed as follows to test the phase measurement accuracy:
1. Connect the Test Tool to the 5502A as shown in Figure 4-5.
2. Select the Test Tool setup:
d) Recall the created 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.
e) Press

(– READING …) and select with
F1
(– READINGS)
and
:
Reading 1, on A, Phase
Reading 2, on B, Phase
Reading 3, on C, Phase
Reading 4, on D, Phase
3. Use
mV
RANGE
and
RANGE
to select range 100 mV/div for A, B, C and D.
4. Use
TIMEsns
to select the required time base setting.
