Performance verification procedures
Use the following procedures to verify the performance of the IsoVu measurement system. Before beginning the procedures, photocopy
the test record and use it to record the performance results.
Required equipment
The equipment required to perform the performance verification procedures are shown in the following table.
Table 3: Required equipment for performance verification
Description
Supported oscilloscope with TekVPI interface 50 Ω input support, fully compatible with
DC voltage source
SMA male short circuit connector cap
(optional)
Digital multimeter (DMM)
One 50 Ω terminator
Precision termination test fixture
TekVPI calibration performance verification
fixture
System RMS Noise
This procedure verifies that the TICP Series probes are functioning and meet the warranted noise specification. The noise will be
measured with no input signal at the most sensitive range.
Before you begin
1. Turn on the TekVPI oscilloscope.
2. Connect the TICP probe to the oscilloscope on channel 1 and remove the TICP probe tip (if attached).
3. Allow the test equipment to warm up for 30 minutes at an ambient temperature of about 20 °C (68 °F).
About this task
This procedure is valid for all versions of the TICP Series probe.
Procedure
1. Tap File > Default Setup.
2. Run Signal Path Compensation, if recommended in Utility > Calibration...
3. Run self-calibration (Self-calibration
4. Connect the TICPSMA probe tip to TICP probe.
5. Connect the SMA short connector cap to TICPSMA.
6. Enable the TICP channel and use the following Vertical menu settings:
