TR31XXX series is the 1 universal oscilloscope current probe, compatible with more than 95% of oscilloscopes on the market, with a frequency response measurement range of up to 20MHz of 50mA to 750A (peak value) and BNC output terminals. Connect an oscilloscope to accurately measure AC or DC current waveforms, and the range can be selected on the handle panel.
Product Features
• High bandwidth precision measurement: DC-20MHz ultra-wide bandwidth, 18ns rise time to capture nanosecond transients
• Dual-range intelligent switching: 0.1V/A(30A) and 0.01V/A(150A) ranges, 10mA high resolution
• Safety protection system: overload red light alarm (≥ 300A),600V CAT II insulation protection
• Industrial accuracy: ± 1 0mA basic accuracy, stable in -40 ℃ ~ 85 ℃ wide temperature range
• Intelligent zero design: a key degaussing (AUTO ZERO), eliminate the residual magnetic field error

High frequency high current probe20MHz bandwidth 150A RMS/300A peak current measurement resolution of 10mA (low range),BNC interface directly connected to Keysight/Tektronix oscilloscope, accurately capture the details of high frequency noise and surge current of switching power supply. |
Jaw intelligentThe Φ19mm jaw dynamic monitoring system senses the bite pressure in real time, and the red light is on when it is not completely locked, so as to prevent the waveform distortion of 20MHz signal caused by virtual connection. |

Automatic/manual zero adjustmentOne-key automatic zero can eliminate the noise floor offset in 0.5 seconds. Traditional probes produce> 5mA error at 30°C temperature difference, while TR3115A maintain ± 1mA zero stability even after 8 hours of standby. Engineers can complete the calibration without interrupting the test process in the high-frequency scenario of the R & D laboratory, ensuring that the 20MHz broadband signal is captured without distortion. |
Dual range designDual range intelligent coverage, a key switch precision worry-free! The TR3115A current probe is equipped with 0.1V/A(30A) and 0.01V/A(150A) dual gear design, which can easily cope with 10mA small current to 150A high power scenarios. The 20MHz ultra-wide bandwidth accurately captures high-speed transient currents with ± 1% accuracy to ensure industrial-grade measurement reliability. Through the panel RANGE button to switch the range, the green indicator real-time feedback status, without interrupting the test process. |
