TR9308A can measure up to 8 kV DC and 6 kV AC voltage, with 100 MΩ input impedance and low loading effect, while its 40 MHz high bandwidth enables capture of fast, high-voltage signals.
The high-voltage probe can be connected directly to an oscilloscope for measurement and is suitable for high-voltage ground-referenced voltage measurement. In addition, an optional adapter allows voltage values to be measured on a digital multimeter.
TR9308A uses an environmentally benign silicone resin insulating dielectric, which improves insulation performance, ensures internal components do not oxidize during high-voltage measurement, and extends service life.
Product Features:
• Maximum measurement voltage: 8 kV DC + AC peak
• Bandwidth up to 40 MHz
• Input impedance 100 MΩ
• Fixed attenuation ratio 1:1000
• Can be connected to a multimeter using an impedance matching adapter
