I am in the market for a high voltage high frequency scope probe (about 1000:1) . Most - even 'used' ones are in excess of $1000.00 . I have one similar already, but it's only good for low frequency use - up to 60Hz..
Hi!
I could recommend the HVP70 70 MHz differential probe from EEVBLOG. The quality of the product is excellent. They recently had a ”sales promotion” with a good discount. I gave about 270 US $. However I don’t know if that offer is still available. The general specs. Are as follows:
Bandwidth DC to 70MHz (-3dB)
Attenuation Ratio 1:10/100
Accuracy ±1%
Rise Time: 5ns
Input
Impedance 4 MΩ, 5.5pF each side to ground
Category CAT III
Differential Range ±70V (DC+AC Peak) and 70Vrms @1/10
±700V (DC+AC Peak) and 700Vrms @1/100
Common Mode Range ±700V (DC+AC Peak) and 700Vrms @1/10 & 1/100
Absolute Max. Voltage ±1400V (DC+AC Peak) and 1000Vrms @1/10 & 1/100 (Differential or Common Mode)
Output
Swing ±7V (into 50
Offset (typical) <±5mV
Noise (typical) 1.5mVrms
Source Impedance (typical) 50Ω (for using 1M input system oscilloscope)
CMRR (typical) -80dB @ 50Hz, -60dB @20kHz -50dB @1MHz, -40dB @ 10MHz
