The Testec is an active differential oscilloscope probe that enables a conventional oscilloscope to display and measure in-circuit waveforms that are referenced to high common-mode voltages. It is capable of safely measuring differential voltages up to ±2500V AC and 7000V ac/dc. It supports bandwidths up to 70MHz.

This oscilloscope probe can measure signals below 700V by selecting the attenuation ration to 1:100.

Bandwidth is DC to 70MHz
Attenuation is 1:100/1:1000
Rise time is 5ns
Differential mode input voltage is 1:100 ±700V (DC+peak AC) or 700Vrms 1:1000 ±7000V (DC+peak AC) or 5000Vrms
Input impedance is 10Mohm ll10pF each side to ground
Common mode voltage range is 1:100 and 1:1000 ±7000V (DC+peak AC) or 2500Vrms
Non-destructive max. input voltage is 1:100 and 1:1000 ±7000V (DC+peak AC) or 2500Vrms
CMRR (typical) is -80dB at 50Hz and -60dB at 20kHz
Offset (typical) is <±5mV
Noise (typical) is 0.9mVRMS
