Figure 1–2: ON/STBY Button
The digitizing oscilloscope automatically performs power-on tests each time it is
turned on. It comes up with a display screen that states whether or not it passed
self test. If the self test does not detect any problems, the status display screen
disappears a few seconds after the self test is complete.
Check the self test results.
If the self test fails, call your local Tektronix Service Center. Depending on the
type of failure, you may still be able to use the oscilloscope before it is serviced.
Press the ON/STBY switch to turn off the oscilloscope.
Before You Begin

your most critical measurements. See Signal Path Compensation on page 3–115
