Adjustment Procedures
This chapter contains the factory adjustment procedure for the DPO2000 Series and the MSO2000 Series oscilloscopes. Only qualied personnel should perform adjustment procedures. Read the Service Safety Summary and the General Safety Summary before performing any service procedures.
Required Equipment
NOTE. The vo
ltage references inside the oscilloscope are very stable over time and should not require routine adjustment. Before performing any procedure in this chapter, do the Performance Verication procedures to check whether the oscilloscope meets specications. See the DPO2000 and MSO2000 Series Specication and Performance Verication Technical Reference.
Successful completion of this adjustment procedure automatically updates the stored time and date of the latest successful adjustment. Completion of the Performance Verication procedure does not update this date and time. If no adjustm
ent is needed, there is also no need to update the time and date of the
adjustment.
The following equipment, or a suitable equivalent, is required to complete these procedures.

Overview of the Adjustment Process
Before pe for at least 20 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 calibration failure.
The factory adjustment procedure consists of a series of steps; as you move through these steps, the oscilloscope display provides instructions that describe the specic input signal requirements for each step. If the oscilloscope passes the step, it moves on to the next step. If the oscilloscope fails, you can repeat the step o

To complete the calibration procedure, you must know how to operate the
lloscope calibrator. Please refer to the user manual, which can be found at
osci http://us.uke.com.
NOTE. Do not turn any knobs or push any front-panel buttons other than the Next
Step or Previous Step buttons during the adjustment procedure. Doing so will cause the oscilloscope to abort the adjustment procedure. The oscilloscope uses the previous calibration constants if the adjustment procedure is aborted or fails.
The screen does not display the signal traces or actual oscilloscope settings (such as channel input impedance, or vertical and horizontal settings) during the adjustment procedure. The oscillosc ope automatically sets the instrument settings, but these settings may not read out correctly on the display.
During some steps, the instrument may appear to be idle for several minutes while it is processing information internally.

To cancel the calibration procedure, press the Menu Off front panel button on the oscilloscope. This reverts the oscilloscope to the old calibration constants.
ustment Procedure
To perform the factory adjustment procedure, complete these steps:
1. Connect the oscilloscope to an AC power source.
NOTE. You must connect the oscilloscope and the test equipment to the same
AC power circuit. Connect the oscilloscope and test instruments to a common power st oscilloscope and test instruments to separate AC power circuits can result in offset voltages between the equipment, which can invalidate the adjustment procedure.
2. Power on the oscilloscope and warm it up for 20 minutes.
3. Power

that and so on.
NOTE. For the DPO2000, there will be either 2 or 4 channels to connect. For
the MSO2000, there will be either 2 or 4 channels to connect, plus an additional channel connection for the digital probe. Plug the digital probe into the Channel 5 active head on the calibrator, using the BNC to square pin adapter, but do not
ug the probe into the oscilloscope until you are directed to by the c alibration
pl process. Once you do plug the digital probe into the oscilloscope, do not unplug it until the adjustment procedure is completed.
5. Access the Factory Adjustment menu:
a. Press the front-panel Utility button, and then press the bottom-bezel
Utility Page button.
b. Use Multipurpose knob a to select Calibration, and then press the
bottom-bezel Factory button. The Factory adjustment passed dialog will appear, as shown below.

General Care
LCD Display Cleaning
How often you do which the oscilloscope is used. A proper time to perform preventive maintenance is just before oscilloscope adjustment.
The cabinet helps keep dust out of the oscilloscope, and is essential for proper cooling. The cabinet needs to be in place when operating the oscilloscope.
The LCD should be treated with care during cleaning.
CAUTION. Improper cleaning agents or methods can damage the at panel
display.
Avoid using abrasive cleaners to clean the display surface.
Avoid spraying liquids directly on the display surface.
Avoid scrubbing the display with excessive force.
Clean the LCD surface by gently rubbing the display with a clean-room wipe (such as Wypall Medium Duty Wipes, #05701, available from Kimberly-Clark Corporation).

Interior Cleaning
Exterior Cleaning
Use a dry, low-velocity stream of air to clean the interior of the chassis. Use a soft-bristle, non-static-producing brush for cleaning around components. If you must use a liquid for minor interior cleaning, use a 75% isopropyl alcohol solution and rinse with deionized water.
WARNING. To avoid injury or death, power down the instrument and disconnect it
from line voltage before performing any procedure that follows.
Clean the exterior surfaces with a dry lint-free cloth or a soft-bristle brush. If any dirt remains, use a cloth or swab dipped in a 75% isopropyl alcohol solution. Use a swab to clean narrow spaces around controls and connectors. Do not use abrasive compounds on any part of the chassis that may damage the chassis.
CAUTION. Avoid the use of chemical cleaning agents, which might damage the
plastics used in this oscilloscope. Use only deionized water when cleaning the menu buttons or front-panel buttons. Use a 75% isopropyl alcohol solution as a cleaner and rinse with deionized water. Before using any other type of cleaner, consult your Tektronix Service Center or representative.
Lubrication. There is no periodic lubrication required for this oscilloscope.

alcohol (75% solution) and rinsed with warm deionized water. (A cotton-tipped applicator is useful for cleaning in narrow spaces and on circuit boards.)
STOP. If, after doing steps 1 and 2, a module is clean upon inspection, skip the following steps.
If there is still dust or dirt on the module, the oscilloscope may be spray washed using a solution of 75% isopropyl alcohol by doing the following steps:
1. Gain access to the parts to be cleaned by removing easily accessible shields and panels. (See page 18.)
2. Spray wash dirty parts with the isopropyl alcohol and wait 60 seconds for the majority of the alcohol to evaporate.
3. Use hot (120 °F to 140 °F) deionized water to thoroughly rinse them.
4. Dry all parts with low-pressure, deionized air.
5. Dry all components and assemblies in an oven or drying compartment using
low-temperature (125 °F to 150 °F) circulating air.
