10. Push the Factory screen button.
11. Push the OK Do Factory Calibration screen button to start the adjustment
process.
12. Connect signals from the DC voltage source, leveled sine w ave, or fast-rise
generator as instructed by the oscilloscope display. After you connect the
correct signal, push the OK Do Next Step screen button to continue the
process.
NOTE. The oscilloscope adjusts itself automatically using the reference signal
from the DC voltage sour ce, leveled sine wave, or fast-rise generator. Ther e are
no manual oscilloscope adjustments that you need to make.
If you make an error, such as connecting the wrong input signal, you can repeat
the last step by pushing the Return to Previous Screen screen button.
13. Continue the adjustment process until it is complete. You can abort the
process at any time by pushing the MENU OFF button or by changing to a
different menu.
14. Do the performance verification tests (found in the Specifications and
Performance Verification technical reference, available on the Web at
www.tektronix.com/manuals) to verify that the adjustment procedure has
correctly calibrated the oscilloscope. Incorrect use of calibration equipment
can cause the oscilloscope to pass the adjustment procedure but fail
performance verification. Refer to the note on page 3--4 regarding possible
injected noise for 0.000V DC input levels.
