Section 4: Using the Model 9100: Logic-Levels Function 4.17-7
Final Width = 215mm
4.17.6.2 Using the 9100 as a Fixed Source
The following procedure assumes that the instrument is in Manual Mode. In the case of
difficulty, re-read Section 3; sub-section 3.3.1. Familiarity with the methods of editing
screen values is also assumed (Section 3).
9100 and UUT Setup
1. Connections Connect the 9100 to the UUT as shown in Fig. 4.17.1, and ensure
that both instruments are powered ON and warmed up.
2. UUT Select Logic-Levels function.

Follow the correct sequence of calibration stages as directed by the guide, and carry out
the following operations (1) to (5) at each stage.
1. 9100 Use the front panel controls to set the 9100 Output to select the UUT
cal point logic signal and set the required parameters:
TTL signal, or CMOS signal, or ECL signal.
Voltage Level (use 'H' or 'L' screen keys if required),
2. UUT Select the correct range or response for the cal point.
3. 9100 a. Set Output ON.
b. Note the UUT reading or response.
4. UUT a. If a UUT calibration adjustment is provided, adjust the UUT
reading or response to be appropriate to the 9100 screen settings,
as detailed in the UUT Manufacturer's Calibration Guide.
b. If no adjustment is provided on the UUT, record the UUT
reading or response at the calibration point as detailed in the
UUT Manufacturer's Calibration Guide.
