Performance veri fi cation
Check the input offset range and scale accuracy
Use the following test to check the input offset range and scale accuracy of the probe.
1. Connect the test equipment as shown in the DC setup diagram. (See Figure 6.)
2. Before attaching the probe to the TekVPI Calibration Veri fi cation adapter, measure the resistance of the feed-thru
termination with the DMM.
3. Record its value. If it is out of speci fi cation, replace it before continuing the test.
4. Attach the probe to the TekVPI Calibration Veri fi cation adapter.
5. Set the DMM to DC Volts autoranging.
6. Set the DC source current limit to 3 mA.
7. Sweep the DC source through the discrete points listed in the following table and set the probe offset range to the same
set point using the Probe Setup window on the oscilloscope. Measure the probe response at each point with the DMM.
DC source voltage Probe vertical offset setting
+12 V +12 V
+1 V +1 V
–1 V –1 V
–12 V –12 V
8. Record the result of each setting in the test record. (See page 34.)
