Important safety information
Connect the probe output to the measurement instrument 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 instrument.
De-energize the circuit under test before connecting or disconnecting the current probe.

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 float the common terminal above the rated voltage for that terminal.
The measurement terminals on this product are not rated for connection to Category III or IV circuits.
Do not connect a current probe to any wire that carries voltages above the current probe voltage rating.

Refer to the installation instructions in the manual for details on installing the product so it has proper ventilation.
2 Series Mixed Signal Oscilloscopes MSO22 and MSO24 Specifications and Performance Verification 5
Important safety information
Slots and openings are provided for ventilation and should never be covered or otherwise obstructed. Do not push objects into any of the
openings.
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.
Use only the Tektronix rackmount hardware specified for this product.
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:

The term under the square root sign is stability and is due to Time Interval Error (TIE). The errors due
to this term occur throughout a single-shot measurement. The second term is due to both the absolute

Input coupling on the clock and data channels must be the same.
For setup time, positive numbers mean a data transition before the clock.
For hold time, positive numbers mean a data transition after the clock edge.

Performance verification procedures
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 2 Series MSO instruments. Completion of the performance verification procedure does not update the
instrument time and date.
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.
The following table lists the required equipment. You might need additional cables and adapters, depending on the actual test equipment
you use.

6. Double-tap the Trigger badge.
7. Tap Slope and change the slope to rising edge.
8. Set the Source to the appropriate channel, such as D0.
By default, the Type is set to Edge, Coupling is set to DC, Slope is set to Rising, Mode is set to Auto, and Level is set to match the
threshold of the channel being tested.
9. Tap outside the menu to close it.
10. Set the DC voltage source (Vs) to -400 mV. Wait 3 seconds. Check the logic level of the corresponding digital channel in the display.
If the channel is a static logic level high (green), change the DC voltage source Vs to -500 mV.
11. Increment Vs by +20 mV. Wait 3 seconds and check the logic level of the corresponding digital channel in the display. If the channel
is at a static logic level high (green), record the Vs value as in the 0 V row of the test record.
If the channel is a logic level low (blue) or is alternating between high and low, repeat this step (increment Vs by 20 mV, wait
3 seconds, and check for a static logic high). Continue until a value for Vs- is found. In this procedure, the channel might not change
state until after you pass the set threshold level.
12. Double-tap the Trigger badge.
13. Tap Slope and change the slope to falling edge.
14. Tap outside the menu to close it.
15. Set the DC voltage source (Vs) to +400 mV. Wait 3 seconds. Check the logic level of the corresponding digital channel in the display.
If the channel is a static logic level low (blue), change the DC voltage source Vs to +500 mV.
16. Decrement Vs by -20 mV. Wait 3 seconds and check the logic level of the corresponding digital channel in the display. If the channel
is at a static logic level low, record the Vs value as Vs+ in the 0 V row of the test record.
If the channel is a logic level high (green) or is alternating between high and low, repeat this step (decrement Vs by 20 mV, wait
3 seconds, and check for a static logic low). Continue until a value for Vs+ is found.
17. Find the average, V
= (Vs- + Vs+)/2. Record the average as the test result in the test record.

is at a static logic level low, record the Vs value as Vs+ in the 4 V row of the test record.
If the channel is a logic level high (green) or is alternating between high and low, repeat this step (decrement Vs by 20 mV, wait
3 seconds, and check for a static logic low). Continue until a value for Vs+ is found.
