Analog galvanic isolator – DC to 1 MHz


SKU: ANA-1 Category:


EMCgear Analog isolator ANA-1 is versatile measuring equipment based on high-accuracy optical isolator in combination with isolated DC-DC converter. Input side is isolated from output as well as power supply jack and doesn’t require separate power supply.

Using isolator with oscilloscope and probe, makes probe differential and eliminate galvanic connection between probe and earth reference of the oscilloscope. This allows to make measurements between any two points of scoped circuit without shorting them with probe GND clip (e.g. high-side measurements in SMPS, measurement between floating points,..)

Thanks to the excellent accuracy can be also used for any type of measurements in DC / AC with basic accuracy better than 1%.
