Section 4: Using the Model 9500B — DC/Square Function 4.5-7
Final Width = 215mm
Descriptions assume 9500B/1100
Sequence of Operations
Refer to the table or list of UUT Oscilloscope
amplitude calibration points in the UUT
Oscilloscope Manufacturer's Calibration
Guide.
Follow the sequence of calibration stages as
directed by the guide, and carry out the
following operations (1) to (6) at each stage.
1. 9500B
Use the front panel controls to set the 9500B
Output to the required square wave p-p voltage,
polarity, frequency and load impedance for the
UUT 'Scope amplitude cal point:
2. UUT 'Scope
a. Select the correct channel for the cal point.
b. Select the correct range for the cal point.
3. 9500B Set Output ON.
4. UUT 'Scope
a. Adjust the sweep speed and trigger level
for a stable display.
b. Observe and note the amplitude response.
5. Calibration
a. Use the 9500B Deviation control to slew
the 9500B Output voltage until the UUT's
response is appropriate to the 9500B
settings, as detailed in the UUT
Oscilloscope Manufacturer's Calibration
Guide.
b. Record the 9500B screen output voltage as
detailed in the UUT Oscilloscope
Manufacturer's Calibration Guide.
6. 9500B Set Output OFF.
4.5.6.4 UUT Oscilloscope —
Amplitude Calibration using
the 9500B as an Adjustable
Source
The following procedure assumes that the
9500B instrument is in Manual Mode. It is also
assumed that the user will be familiar with the
methods of editing screen values. In the case
of difficulty, re-read the paragraphs earlier in
this Section 4.
9500B and UUT Oscilloscope Setup
1. Preparation
Ensure that both instruments are powered ON
and warmed up.
2. UUT 'Scope
Select the required function for amplitude
calibration.
3. 9500B
Ensure that the 9500B is in Square Function
with Output OFF. If in any other function,
press the
soft key at the top right of the
screen.
