Delta time measurement
accuracy
Frequency response tolerance,
typical
The formula to calculate delta-time measurement accuracy (DTA) for a given instrument setting and input
signal is given below (assumes insignificant signal content above Nyquist).
SR1 = Slew Rate (1st Edge) around the 1st point in the measurement
SR2 = Slew Rate (2nd Edge) around the 2nd point in the measurement
N = input-referred noise (voltsrms, refer to the Random Noise, Sample acquisition mode specification)
tsr = 1 / (Sample Rate)
TBA = timebase accuracy (refer to the Long-term sample rate and delay time accuracy specification)
tp = delta-time measurement duration
RD = (Record Length) / (Sample Rate)
Assumes that error due to aliasing is insignificant.
The term under the square-root sign is the stability, and is related to the TIE (Time Interval Error). The errors
from this term occur throughout a single-shot measurement. The second term is a result of 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 singleshot measurement to the final single-shot measurement).

Performance Verification Procedures
The following three conditions must be met prior to performing these procedures:
1. The oscilloscope must have been operating continuously for ten (10) minutes in an environment that meets the operating range
specifications for temperature and humidity.
2. You must perform a signal path compensation (SPC). (See Self Tests — System Diagnostics and Signal Path Compensation section
below.) If the operating temperature changes by more than 5 °C (41 °F), you must perform the signal path compensation again.
3. You must connect the oscilloscope and the test equipment to the same AC power circuit. Connect the oscilloscope and test
instruments into a common power strip if you are unsure of the AC power circuit distribution. Connecting the oscilloscope and test
instruments into separate AC power circuits can result in offset voltages between the equipment, which can invalidate the performance
verification procedure.
The time required to complete all the procedures is approximately one hour.
Warning: Some procedures use hazardous voltages. To prevent electrical shock, always set voltage source outputs to 0 V before
making or changing any interconnections.
Self Tests, System Diagnostics, and Signal Path Compensation
These procedures use internal routines to verify that the oscilloscope functions and passes its internal self tests. No test equipment or
hookups are required. Start the self test with these steps:
Run the System Diagnostics (may take several minutes):
1. Disconnect all probes and cables from the oscilloscope inputs.
2. Push Default Setup on the front-panel to set the instrument to the factory default settings.
3. Tap Utility > Self Test. This displays the Self Test configuration menu.
4. Tap the Run Self Test button.
5. Wait while the self test runs. When the self test completes, a dialog box displays the results of the self test.
6. Verify that the status of all tests is Passed.
7. Cycle the oscilloscope power off and back on before proceeding.
Note: Remember to cycle the oscilloscope power off and back on before proceeding.
Run the signal-path compensation routine (may take 5 to 15 minutes per channel):
1. Push Default Setup on the front panel.

Verifies the maximum frequency.
3 Series MDO Mixed Domain Oscilloscope Specifications and Performance Verification 80
Performance verification
2. Tap Utility > Calibration. This displays the Calibration configuration menu.
3. Tap the Run SPC button to start the routine.
4. Signal-path compensation may take 5 to 15 minutes to run per channel.
5. Verify that the SPC Status is Passed.
6. Return to regular service: Tap anywhere outside the menu to exit the Calibration menu.
The self test procedures are completed. If any of the above tests failed, run the tests again. If there are still failures, contact Tektronix
Customer Support.
Note: You cannot run the remaining performance tests until the self tests pass and the SPC has successfully run.
Check Input Termination DC Coupled (Resistance)
This test checks the Input Termination for 1 MΩ or 50 Ω settings.
1. Connect the output of the oscilloscope calibrator (for example, Fluke 9500) to the oscilloscope channel 1 input, as shown below.
Warning: Be sure to set the generator to Off or 0 volts before connecting, disconnecting, and/or moving the test hookup
during the performance of this procedure. The generator is capable of providing dangerous voltages.
Note: Impedance measuring equipment that produces a voltage across the channel that exceeds the measurement range of
the instrument may report erroneous impedance results. A measurement voltage exceeds the measurement range of the
instrument when the resulting trace is not visible on the graticule.
2. Push Default Setup on the front panel to set the instrument to the factory default settings.
3. Push the channel button on the front panel for the oscilloscope channel that you are testing, as shown in the test record (for example,
1, 2, 3, or 4).
4. Confirm that the oscilloscope termination and calibrator impedance are both set to 1 MΩ.
5. Turn the Vertical Scale knob to set the vertical scale, as shown in the test record (for example, 10 mV/div, 100 mV/div, 1 V/div). See
Input Termination Tests on page 38.
6. Measure the input resistance of the oscilloscope with the calibrator. Record this value in the test record.
7. Repeat steps 5 and 6 for each volt/division setting in the test record.
8. Change the oscilloscope termination to 50 Ω and repeat steps 5 through 7.
9. Repeat steps 4 through 9 for each channel listed in the test record and relevant to the model of oscilloscope that you are testing, as
shown in the test record (for example, 2, 3, or 4).
This completes the procedure.
