The Agilent/Keysight 34300A is a high-voltage probe that extends the measurement range of compatible digital multimeters into the high-voltage domain. This 1000:1 voltage divider probe enables safe measurement of voltages up to 40 kV AC/DC peak at sea level, with a 2-meter cable and approximately 1 GΩ input resistance. The probe delivers ±2% division ratio accuracy under DC conditions with 10 MΩ termination and operates across a DC to 150 Hz bandwidth, with -3 dB attenuation at 150 Hz for AC measurements. Input voltage derates 1% per 100 meters above sea level. The probe insulation is rated to 300 V maximum, and the 0.16 inch diameter probe tip facilitates contact with test points across various applications. Operating temperature range is 0°C to +50°C, with storage capability from -20°C to +70°C. Note: This product is obsolete.
