Page 21: Performance Verification
Performance Verification Use the following procedures to verify the warranted specifications of the TDP3500 Differential Probe. Before beginning these procedures, photocopy the test record and use it to record the performance test results. (See Table 6 on page 22.) The recommended calibration interval is one year. -
Page 22: Special Adapters
Performance Verification Special Adapters Some of the adapters used in these procedures are available only from Tektronix. These adapters are described on the following pages. TekVPI Calibration Fixture The TekVPI calibration fixture, Tektronix part number 067-1701-xx, connects between the host instrument and the probe under test. - Page 23 Probe Calibration Fixture The Probe calibration fixture, Tektronix part number 067-0419-xx, provides a means to check the rise time specification of the probe. (See Figure 7.) A probe positioner can be helpful to keep the probe in contact with the fixture.
