Type 8630
Isolation Amplifier Type 8630
Type 8630 enables galvanically isolated, floating measurement of up to four signals with an oscilloscope. It is suitable for basic experiments through to power electronics and can be used as a bench unit or in a demonstration frame.
- 4 floating differential inputs
- Each input switchable to GND, DC or AC
- Selectable low-pass filter
- Fully isolated BNC sockets on all measurement outputs
- Overload indication for all channels
- Galvanic isolation with only 0.008 percent linearity error
Application
The isolation amplifier was designed for floating and safe measurement of different voltages in combination with an oscilloscope. Up to four signals with different reference points can be displayed on one oscilloscope channel.
Operation and mechanics
The front panel is made of 5 mm laminated press material in matte blue. The rear side is protected by a grey plastic housing that also allows the unit to stand at an inclined angle on the desk.
