UUT Current Probe — Amplitude
Calibration using the 9500B as an
Adjustable Source
Sequence of Operations
Refer to the table or list of UUT Oscilloscope
amplitude calibration points in the UUT Scope
Manufacturer's Calibration Guide.
Follow the sequence of calibration stages as
directed by the guide, and carry out the
following operations (1) to (8) at each stage.
1. 9500B
Use the front panel controls to set the 9500B
Output to the required DC current and polarity
for the UUT Probe amplitude cal point:
2. UUT 'Scope
a. Select the correct channel for the cal point.
b. Select 'DC-Coupled', if required.
c. Select the correct range for the cal point.
3. 9500B
Ensure that Output is OFF.
4. UUT 'Scope
a. Set the Y controls to place the trace on
graticule zero.
5. 9500B
Set Output ON.
6. UUT 'Scope
a. Auto-trigger the oscilloscope or use the
100Hz Trigger from the 9500B. Adjust
the UUT for a stable display.
b. Observe and note the DC level change
from graticule zero.
7. Calibration
a. Use the 9500B Deviation control to slew
the 9500B Output current until the UUT
probe's response is appropriate to the 9500B
settings, as detailed in the UUT Scope
Manufacturer's Calibration Guide.
b. Record the 9500B screen output current as
detailed in the UUT Scope Manufacturer's
Calibration Guide.
8. 9500B Set Output OFF.
