Performance Verification Procedures
The following three conditions must be met prior to performing these procedures:
1. The oscilloscope must have been operating continuously for twenty (20) 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 D iagnostics and Sig
nal Path
Compensation section below.) If the operating temperature changes by more than 10 °C (18 °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. Push Utility .
4. Push Utility Page on the lower menu, and turn Multipurpose knob “a” to selec t Self Test.
5. Push Self Test on the lower menu. The Loop X Times side menu button will be set to Loop 1 Times.
6. Push OK Run Self Test on the s ide menu.
7. Wait while the self test runs. When the self test completes, a dialog box displays the results of the self test.
8. 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):
1. Push Default Setup on the front panel.
2. Push Utility .
3. Push Utility Page on the lower menu.
4. Turn M u ltipurpose knob “a” to selec t Calibration.
5. Push Signal Path on the lower menu.
