The Agilent N2790A 100 MHz High-voltage differential probe offers user selectable attenuation settings that make it highly versatile, allowing it to be used for a broad range of applications. It can make safe and accurate floating measurements with an oscilloscope. Performance characteristics. Bandwidth (-3dB): >=100 MHz probe bandwidth. Rise time (calculated): <= 3.5 ns. Attenuation: 50:1 / 500:1. Gain accuracy (% of reading): ± 2% at 20-30°C. DC CMRR: –70 dB at 500 VDC. AC CMRR: –80 dB at 50/60 Hz, –50 dB at 1 kHz, –50 dB at 1 MHz. Propagation delay: 14 nsec at 50:1, 12.8 nsec at 500:1. Input R//C (each input to ground): 4 Mohm // 7 pF. Input R//C (between inputs): 8 Mohm // 3.5 pF. Max differential operating voltage (DC+PeakAC): ±1400 V at 500:1, ±140 V at 50:1. Max common mode operating voltage (RMS or DC+PeakAC): ±1000 V (CAT II), ±600 V (CAT III). Max nondestructive voltage: ±1500 VDC + Peak AC differential mode. Output maximum voltage range: ±2.8V into 1 Mohm (500:1). Output offset: Adjustable. Noise referenced to input: < 300 mVrms at 500:1, < 50 mVrms at 50:1.
