TekVPI Calibration Fixture
This calibration fixture is required to complete a performance verification and gain accuracy adjustment procedures on the probes. It
provides power to the probe and routes the probe output signal out through an SMA connector on the back of the fixture. The signal can
then be measured with another instrument, such as a precision DMM, to check and adjust the gain accuracy of the probe. Order T

est procedures
WARNING: These procedures require the application of high voltage to the inputs of the probes. Only qualified personnel
should perform any testing with voltage levels exceeding 30 V
rms
. All pertinent safety rules and guidelines for elevated voltage
measurements should be followed and adhered to.
Test setup
1. T
urn on the oscilloscope.
2. Connect the probe to any channel of the oscilloscope.
3. Verify that the LEDs light on the probe.
4. T
urn on the remaining test equipment and let the probe and equipment warm up for 20 minutes.
5. Make a copy of the test record to tabulate the test results. See Test record on page 50.
