UT-PA2000UT-PA1000 Active single-ended probe
The probe has a fixed output impedance of 50, and when the probe is connected to an oscilloscope, the oscilloscope’s impedance setting is fixed at 50 and cannot be changed.
Using the front-end of the handheld single-ended probe
The UT-PA2000 probe has an effective bandwidth of up to 2GHz on the front end and the UTPA1000 probe has an effective bandwidth of up to 1GHz on the front end, and the probe tip and ground pin can be replaced and can be used with a variety of flexible accessories to extend probe life. Using the front end of the handheld single-ended probe, the users can conveniently measure single-ended signals. When performing signal measurement, the single-ended ground pin needs to be grounded.
Probe Tip and Ground Tip Connect to DUT Note: Due to the fixed spacing of the probe tip, ensure the ground connection is made as close as possible to the probe tip.
Use probe accessories
The probe is available with a variety of test accessories for different scenarios, and when using these accessories, it is necessary to replace the standard probe pin or the ground pin. 1. Replace the probe tip
Carefully replace the probe tip, handle the replacement process cautiously to avoid damaging the connection and compromising the probe’s performance. Replacement Method Disconnect the active probe from the oscilloscope. Insert the new probe tip vertically into the active probe.

Calibrating the probe
UT-PA2000UT-PA1000 Active single-ended probe
Before using the probe, you need to calibrate the probe, and the probe calibration will effectively adjust the zero offset of the probe, which will ensure the integrity of the measured signal. 1. Connecting the oscilloscope
Refer to the first section Connecting the oscilloscope . After completing the connection, the probe needs to be warmed up for 15 minutes to ensure that the probe enters a stable working state. 2. Access the oscilloscope’s channel menu and click Input Settings > Auto Calibration to perform the probe calibration.
3. Before calibration, you need to make sure that the probe is not connected to any DUT, insert the probe into the oscilloscope channel, connect the probe to the square wave terminal, and then click Auto-Calibration.
www.instruments.uni-trend.com
17
UT-PA2000UT-PA1000 Active single-ended probe
4. Wait for the calibration to be completed. The calibration time depends on the degree of zero offset of the probe, approximately 40 seconds. If this is the first time calibrating the probe, the process may take longer. When calibration is complete, the oscilloscope will display either “Probe Calibration Completed” or “Probe Calibration Failed” based on the results. If the prompt displays “Probe Calibration Failed,” please retry the calibration steps. If calibration fails multiple times, contact UNI-T distributor for assistance.
