Delta-time measurement accuracy, nominal

The formulas to calculate the peak-to-peak or rms nominal delta-time measurement accuracy (DTA) for a given instrument setting and input signal is as follows (assumes insignificant signal content above Nyquist frequency):



Where:

N = RSS of input-referred noise (VRMS) and dynamic noise estimate (VRMS)

SR 1 = Slew Rate (1st Edge) around 1st point in measurement

SR 2 = Slew Rate (2nd Edge) around 2nd point in measurement

Dynamic noise is noise that appears with a signal applied (such as distortion or interleave errors).

Dynamic noise estimate =

Tj = aperture uncertainty (sec rms - 80 fs for short durations)

t p = delta-time measurement duration (sec)

TBA = timebase accuracy or Reference Frequency Error (which is 20 ppb)

(Assumes insignificant error due to aliasing or over-drive.)

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).

Note:The formulas assume negligible errors due to measurement interpolation, and apply only when the interpolated sample rate is 25 GS/s or higher.

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 LPD64 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.

Performance tests

This section contains a collection of manual procedures for checking that the instrument performs as warranted. They check all the characteristics that are designated as checked in Specifications. (The characteristics that are checked appear with a ✔ in Specifications).

Prerequisites

The tests in this section comprise an extensive, valid confirmation of performance and functionality when the following requirements are met:

  • The instrument must be in its normal operating configuration (no covers removed).

  • You must have performed and passed the procedures under Self Test. (See Self test.)

  • A signal-path compensation must have been done within the recommended calibration interval and at a temperature within ±5 ºC (±9 ºF) of the present operating temperature. (If the temperature was within the limits just stated at the time you did the prerequisite Self Test, consider this prerequisite met). A signal-path compensation must have been done at an ambient humidity within 25% of the current ambient humidity and after having been at that humidity for at least 4 hours.

  • The instrument must have been last adjusted at an ambient temperature between +18 ºC and +28 ºC (+64 ºF and +82 ºF), must have been operating for a warm-up period of at least 20 minutes, and must be operating at an ambient temperature as listed in the specifications. The warm-up requirement is usually met in the course of meeting the Self Test prerequisites listed above.

  • The instrument must be powered from a source maintaining voltage and frequency within the limits described in the Specifications section.
  • The instrument must be in an environment with temperature, altitude, humidity, and vibration within the operating limits described in the Specifications section.

Self test

This procedure verifies that the instrument passes the internal diagnostics and performs signal path compensation. No test equipment or hookups are required.

Equipment required Prerequisites
NonePower on the instrument and allow a 20 minute warm-up period before performing this procedure.
  1. Run the System Diagnostics (may take a few minutes):

    1. Disconnect all probes and/or cables from the oscilloscope inputs.

    2. Tap Utility > Self Test. This displays the Self Test configuration menu.

    3. Tap the Run Self Test button.

    4. The internal diagnostics perform an exhaustive verification of proper instrument function. This verification may take several minutes. When the verification is finished, the status of each self test is shown in the menu.

    5. Verify that the status of all tests is .

    6. Tap anywhere outside the menu to exit the menu.
  2. Run the signal-path compensation routine (may take 5 to 15 minutes per channel):

    1. Tap Utility > Calibration. This displays the Calibration configuration menu.

    2. Tap the Run SPC button to start the routine.

    3. Signal-path compensation may take 5 to 15 minutes to run per channel.
