These differential probes aggregate a certain number of electrical specifications which include a 70 MHz bandwidth (-3 dB), up to ±7 kV differential and common mode voltage ,and, selectable attenuation settings of 100x/1000x. In fact, as far as probes are concerned, the CT3683 has very unique high voltage input leads and hook probes. Another particularity is the fact that it is compatible with most oscilloscopes which means that it is a very versatile device.
As for the mechanical characteristics, it has input leads length of 60 cm each, a BNC cable length of 90 cm, and dimensions and weight of 202 x 83 x 38 mm and 500 g respectively. Accordingly, to ensure that it continues to function in extreme conditions, the device can withstand an operating Temp/Humidity of -10°C to 40°C / 25% to 85% RH, as well as a storage Temp/ Humidity of -30°C to 70°C / 25% to 85% RH.
Review of Key Specifications
In sum, the CT3681 and CT3683 both offer a 70 MHz bandwidth and can test up to ±7 kV (DC + AC peak). Secondly, it is compatible with oscilloscopes from all major manufacturers. Thirdly, the probes are not only be battery operated, but they can also be powered by an optional universal adapter or even by an optional USB power lead – only if the device is equipped with those optional features.
Other features include, a source Impedance of 50 Ω, as well as an input Impedance of 50 MΩ // 7 pF (each side to ground) and 100 MΩ // 5 pF (between inputs).
