UT-P31
High voltage differential probe: (100:1/1000:1) Bandwidth: 100MHz differential voltage: 1500Vpp
The high-voltage differential probe offers selectable ratios of (10:1/100:1), a bandwidth of 100MHz, and the capability to handle differential voltages of ±1500Vpp. This probe is designed for precise and high-frequency measurements in applications requiring the analysis of significant voltage differentials. Before use, it is essential to review the safety instructions provided in the user guide.
The UNI-T UT-P31 Differential Probe provides a safe and reliable measurement solution for use with oscilloscopes. It converts high differential input voltages (≤1500V Peak) into a low-voltage signal (≤7V) that can be displayed and analyzed on an oscilloscope. With a bandwidth of up to 100MHz, it is ideal for high-power testing, research and development, troubleshooting, and maintenance applications.
The probe's attenuation values are specified for oscilloscopes with a 1MΩ input impedance. When used with a 50Ω terminator, the attenuation factor becomes twice the indicated value.
For extended applications, the UT-P31 can also be used with the PL-10 Impedance Converter, allowing more accurate voltage measurements using a digital multimeter. While a typical oscilloscope offers approximately 1% accuracy, a digital multimeter can provide significantly higher measurement precision.
