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.
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.
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. Do not use the
provided power cord for other products.
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.
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.
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. 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.

✓Delta-time measurement
accuracy
The formula to calculate delta-time measurement accuracy (DTA) for a given instrument setting
and input signal is as follows (assumes insignificant signal content above Nyquist frequency):
SR 1 = Slew Rate (1st Edge) around 1st point in measurement
SR 2 = Slew Rate (2nd Edge) around 2nd point in measurement
N = input-referred guaranteed noise limit (V
TBA = timebase accuracy or Reference Frequency Error

DTA
RMS
The term under the square root sign is the stability and is due to TIE (Time Interval Error). The
errors due to this term occur throughout a single-shot measurement. The second term is due to
both the absolute center-frequency accuracy and the center-frequency stability of the timebase and
varies between multiple single-shot measurements over the observation interval (the amount of
time from the first single-shot measurement to the final single-shot measurement).

305 Series MSO Specifications and Performance Verification
Performance verification procedures
This chapter contains performance verification procedures for the specifications marked with the symbol. The following
equipment, or a suitable equivalent, is required to complete these procedures.
The performance verification procedures verify the performance of your instrument. They do not adjust your instrument. If your
instrument fails any of the performance verification tests, repeat the failing test, verifying that the test equipment and settings are
correct. If the instrument continues to fail a test, contact Tektronix Customer Support for assistance.
These procedures cover all MSO58, MSO56, and MSO54 models, and the MSO58LP.
Print the test records on the following pages and use them to record the performance test results for your oscilloscope. Disregard
checks and test records that do not apply to the specific model you are testing.
NOTE. Completion of the performance verification procedure does not update the instrument time and date.
