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.

Check digital threshold accuracy with 2-MSO option

This procedure checks the threshold accuracy of the digital channels and is for models with the 2-MSO option only.
About this task
This procedure applies to digital channels D0 through D15, and to channel threshold values of 0 V and 4 V.
Procedure

5. You need to record the test values in the test record row for 0 V for each digital channel. See Digital threshold accuracy performance
checks table.
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.
