Adjustment Procedure
Before Adjustments
NOTE.
The voltage references inside the oscilloscope are very stable over time
and should not require routine adjustment.
Before performing the adjustment procedure, do the following:
Read the Service Safety Summary and the General Safety Summary at the
front of this manual.
Perform the Performance Veri fi cation procedures. If the oscilloscope is
operating within speci fi cations, you do not need to make any adjustments.
(See the MSO4000B Series and DPO4000B Series Oscilloscopes
Speci fi cations and Performance Veri fi cation Technical Reference manual ,
which was provided with your product. This manual is also available at
www.tektronix.com/manuals.)
Before performing the adjustment procedure, you must warm up the
oscilloscope and the oscilloscope calibrator for at least 30 minutes in an
ambient temperature between 20 °C and 30 °C. Adjustments performed before
warm-up or outside this temperature range may result in poor performance or
failure of the adjustment procedure.
Learn how to operate the oscilloscope calibrator. Refer to the user manual,
which can be found at http://us. fl uke.com.
Navigating During Adjustments
Continue. Once you have set the calibrator output signal that is speci fi ed
on the oscilloscope screen, push the OK Do Next Step side-bezel button to
proceed. Information about setting up the calibrator output signal is provided
after the Factory Adjustment Procedure. (See page 13,
Setting the Calibrator
Output Signal .)
Go back. Push the Return to Previous Screen side-bezel button to go back
to the previous step. Push the button multiple times if you want to go back
multiple steps.
Abort. Push the Menu Off front-panel button on the oscilloscope to cancel the
procedure at any time. This causes the oscilloscope to revert to the previous
calibration constants. The
last factory calibration date will not be updated.
