Adjustment Procedure
The adjustment procedure consists of 70 steps for the two-channel oscilloscope,
and 106 steps for the four-channel model. Each step requires an external voltage
source for new calibration constants.
Before performing the adjustment procedure, warm up the oscilloscope for at
least ten minutes in an ambient temperature between 20 °C and 30 ° C. Adjust-
ments performed prior to warm-up or outside this temperature range may result
in poor performance.
If all steps in the procedure are completed successfully, a “Pass” message is
displayed and the new calibration constants take affect. If any step fails, the
procedure is aborted and the current calibration is not affected. You can choose to
abort the procedure at any step, without affecting the current calibration, by
selecting FCAL ABORT.
NOTE. While performing the adjustment procedure, keep in mind that some of the
steps take a significant amount of time (up to 5 minutes) to complete.
The equipment setups, shown in Figure 5--1, are required to complete the
adjustment procedure. Table 5--2 on page 5--6 lists the steps in the procedure
and the signal requirement for each step.
You must enable the Service menu to perform the adjustment procedure. To do
this:
1. Power on the oscilloscope.
2. Push the front-panel MEASURE button to access the MEASURE menu.
3. Push the top option button to access the Measure 1 menu.
4. Push and hold the front-panel SINGLE SEQ button.
5. Push and hold the front-panel AUTOSET button.
6. Wait at least two seconds.
