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
Use proper power cord Use only the power cord specified for this product and certified for the country of use.
Ground the product This product is grounded through the grounding conductor of the power cord. To avoid
electric shock, the grounding conductor must be connected to earth ground. Before making
connections to the input or output terminals of the product, ensure that the product is properly
grounded. Do not disable the power cord grounding connection.
Ground-referenced oscilloscope use Do not float the reference lead of this probe when using with ground-referenced oscilloscopes.
The reference lead must be connected to earth potential (0 V).
Power disconnect The power cord disconnects the product from the power source. See instructions for the
location. Do not position the equipment so that it is difficult to operate the power cord; it must
remain accessible to the user at all times to allow for quick disconnection if needed.
Connect and disconnect properly Do not connect or disconnect probes or test leads while they are connected to a voltage
source.
Use only insulated voltage probes, test leads, and adapters supplied with the product, or
indicated by Tektronix to be suitable for the product.
Observe all terminal ratings To avoid fire or shock hazard, observe all rating and markings on the product. Consult the
product manual for further ratings information before making connections to the product. Do
not exceed the Measurement Category (CAT) rating and voltage or current rating of the lowest
rated individual component of a product, probe, or accessory. Use caution when using 1:1 test
leads because the probe tip voltage is directly transmitted to the product.
Do not apply a potential to any terminal, including the common terminal, that exceeds the
maximum rating of that terminal.
TBS1000C Series Oscilloscope Specification and Performance Verification 5
Important safety information
Do not float the common terminal above the rated voltage for that terminal.
Do not operate without covers Do not operate this product with covers or panels removed, or with the case open. Hazardous
voltage exposure is possible.
Avoid exposed circuitry Do not touch exposed connections and components when power is present.
Do not operate with suspected
failures
Do not operate in wet/damp
conditions
Do not operate in an explosive
atmosphere
Keep product surfaces clean and dry Remove the input signals before you clean the product.
Provide proper ventilation Refer to the installation instructions in the manual for details on installing the product so it has
Provide a safe working environment Always place the product in a location convenient for viewing the display and indicators.
If you suspect that there is damage to this product, have it inspected by qualified service
personnel.
Disable the product if it is damaged. Do not use the product if it is damaged or operates
incorrectly. If in doubt about safety of the product, turn it off and disconnect the power cord.
Clearly mark the product to prevent its further operation.
Before use, inspect voltage probes, test leads, and accessories for mechanical damage and
replace when damaged. Do not use probes or test leads if they are damaged, if there is
exposed metal, or if a wear indicator shows.
Examine the exterior of the product before you use it. Look for cracks or missing pieces.
Use only specified replacement parts.
Be aware that condensation may occur if a unit is moved from a cold to a warm environment.
proper ventilation.
Slots and openings are provided for ventilation and should never be covered or otherwise
obstructed. Do not push objects into any of the openings.
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.
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: To prevent electrical shock, do not exceed the maximum measurement
or maximum floating voltage for the oscilloscope input BNC connector, probe tip, or
probe reference lead.
TBS1000C Series Oscilloscope Specification and Performance Verification 6
Important safety information
Connect and disconnect properly Connect the probe output to the measurement product before connecting the probe to the
circuit under test. Connect the probe reference lead to the circuit under test before connecting
the probe input. Disconnect the probe input and the probe reference lead from the circuit under
test before disconnecting the probe from the measurement product.
Connect and disconnect properly De-energize the circuit under test before connecting or disconnecting the current probe.
Connect the probe reference lead to earth ground only.
Do not connect a current probe to any wire that carries voltages or frequencies above the
current probe voltage rating.
Inspect the probe and accessories Before each use, inspect probe and accessories for damage (cuts, tears, or defects in the
probe body, accessories, or cable jacket). Do not use if damaged.

Performance verification procedures
Before beginning these procedures, two conditions must be met:
• The oscilloscope must have been operating continuously for twenty minutes within the operating temperature range specified in the
Environmental Performance table.
• You must perform the Self Calibration operation described below. If the ambient temperature changes by more than 5 °C, you must
perform the Self Calibration operation again.
The time required to complete the entire procedure is approximately one hour.
Warning:
making or changing any interconnections.
Self test
This internal procedure is automatically performed every time the oscilloscope is powered on. No test equipment or hookups are required.
Verify that no error messages are displayed before continuing with this procedure.
1
The bandwidth test does not have a high limit.
2
The limits vary by model. Check the procedure for the correct limits.
Some procedures use hazardous voltages. To prevent electrical shock, always set voltage source outputs to 0 V before
