Final Width = 215mm
4.17.6.3 Using the 9100 as an Adjustable Source
The following procedure assumes that the instrument is in Manual Mode. In the case of
difficulty, re-read sub-section 3.3.1. Familiarity with the methods of editing screen
values is also assumed (Section 3).
Calibration 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.
3. 9100 Ensure that the 9100 is in Logic-Levels Function with Output OFF.
If in any other function, press the
Aux key on the right of the front
panel, then the LOGIC screen key on the bottom row. Finally press
the 1/Ø screen key on the bottom row.
Sequence of Operations
Refer to the table of UUT calibration points in the UUT Manufacturer's Calibration
Guide. 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. Slew the Logic-Levels Output reading until the UUT reading or
response is appropriate to the screen Output settings.
4. UUT Record the 9100 screen output settings as detailed in the UUT
Manufacturer's Calibration Guide.
5. 9100 Set Output OFF.
