Important safety information
Important safety information
This manual contains information and warnings that must be followed by the user for safe operation and to keep the product in a safe
condition.
To safely perform service on this product, see the Service safety summary that follows the General safety summary.
General safety summary
Use the product only as specified. Review the following safety precautions to avoid injury and prevent damage to this product or any
products connected to it. Carefully read all instructions. Retain these instructions for future reference.
This product shall be used in accordance with local and national codes.
For correct and safe operation of the product, it is essential that you follow generally accepted safety procedures in addition to the safety
precautions specified in this manual.
The product is designed to be used by trained personnel only.
Only qualified personnel who are aware of the hazards involved should remove the cover for repair, maintenance, or adjustment.
Before use, always check the product with a known source to be sure it is operating correctly.
This product is not intended for detection of hazardous voltages.
Use personal protective equipment to prevent shock and arc blast injury where hazardous live conductors are exposed.
While using this product, you may need to access other parts of a larger system. Read the safety sections of the other component manuals
for warnings and cautions related to operating the system.
When incorporating this equipment into a system, the safety of that system is the responsibility of the assembler of the system.
To avoid fire or personal injury
Provide a safe working
environment.
Always place the product in a location convenient for viewing the display and indicators.
Avoid improper or prolonged use of keyboards, pointers, and button pads. Improper or prolonged keyboard
or pointer use may result in serious injury.
Be sure your work area meets applicable ergonomic standards. Consult with an ergonomics professional to
avoid stress injuries.

Important safety information
Probes and test leads
Before connecting probes or test leads, connect the power cord from the power connector to a properly grounded power outlet.
Keep fingers behind the protective barrier, protective finger guard, or tactile indicator on the probes. Remove all probes, test leads and
accessories that are not in use.
Use only correct Measurement Category (CAT), voltage, temperature, altitude, and amperage rated probes, test leads, and adapters for
any measurement.
Beware of high voltages. Understand the voltage ratings for the probe you are using and do not exceed those ratings. Two ratings are
important to know and understand:
• The maximum measurement voltage from the probe tip to the probe reference lead.
• The maximum floating voltage from the probe reference lead to earth ground.
These two voltage ratings depend on the probe and your application. Refer to the Specifications section of
the manual for more information.
WARNING
Electric shock
Do not exceed the maximum measurement or maximum floating voltage for the oscilloscope input BNC
connector, probe tip, or probe reference lead.
Service safety summary
The Service safety summary section contains additional information required to safely perform service on the product. Only qualified
personnel should perform service procedures. Read this Service safety summary and the General safety summary before performing any
service procedures.

Specifications
This chapter contains specifications for the instrument. All specifications are guaranteed unless noted as "typical." Typical specifications
are provided for your convenience but are not guaranteed. Specifications that are marked with the symbol are checked in Performance
Verification.
All specifications apply to all models unless noted otherwise. To meet specifications, two conditions must first be met:
• The instrument must have been operating continuously for twenty minutes within the specified operating temperature range.
• You must perform the Signal Path Compensation (SPC) operation described in ... If the operating temperature changes by more than
10 °C (18 °F), you must perform the SPC operation again.

Performance verification procedures
Note: If your instrument firmware version is v1.02, it should be updated before performing the performance verification
procedures. Download the latest firmware from www.tek.com/software.
The following three conditions must be met prior to performing these procedures:
• The instrument must have been operating continuously for twenty (20) minutes in an environment that meets the operating range
specifications for temperature and humidity.
• You must perform a signal path compensation (SPC) before beginning these procedures. If the operating temperature changes by
more than 10 °C (18 °F), you must perform the signal path compensation again.
• You must connect the instrument and the test equipment to the same AC power circuit. Connect the instrument and test instruments
into a common power strip if you are unsure of the AC power circuit distribution. Connecting the instrument and test instruments into
separate AC power circuits can result in offset voltages between the equipment, which can invalidate the performance verification
procedure.
The time required to complete the entire procedure is approximately one hour.
Warning: Some procedures use hazardous voltages. To prevent electrical shock, always set voltage source outputs to 0 V before
making or changing any interconnections.
Self test
This procedure uses internal routines to verify that the instrument functions and passes its internal self tests. No test equipment or hookups
are required. Start the self test with these steps:
1. Disconnect all probes and cables from the instrument inputs.
2. Push the front-panel Default Setup button to set the instrument to the factory default settings.
3. Push the Utility menu button.
4. Push the Utility Page bezel button, the Diagnostics bezel button, the Self Test bezel button, and turn Multipurpose knob a to select
Loop Times.
5. Push the Multipurpose knob a to select Loop Times, and turn the Multipurpose knob a to select Loop 1 Times.
6. Push the Multipurpose knob a to set the Loop Times to 1.
7. Turn Multipurpose knob a to select Run Self Test, and push the Multipurpose knob a to start the self tests.
8. Wait while the self test runs. When the self test completes, a dialog box displays the results of the self test.
9. Push the Menu Off button to clear the dialog box and Self Test menu.
Signal path compensation (SPC)
This process corrects for DC inaccuracies caused by temperature variations and/or long term drift.
1. Remove all input signals (probes and cables) from channel inputs. Input signals with AC components adversely affect SPC.
2. Push the front-panel Utility button, and then push the Utility Page bezel button.
3. Push the Calibration bezel button.
4. Turn the Multipurpose button a to select Signal Path, and then push Multipurpose knob a to select Calibration Signal Path.
5. Push the Compensate Signal Paths bezel button.
6. Wait while the Signal Path Compensation runs. On completion a dialog box informs you whether the Compensation completed
successfully or not.
7. Push the Menu Off button to clear the dialog box and Self Test menu.
