Siglent Isolation Channel Option (ISFE)

Siglent’s ISFE (Isolated Signal Front End) is designed to measure high voltages safely with any digital oscilloscope. It is suitable for SIGLENT’s full range of oscilloscope products. It is powered from a USB port 5V power supply from the oscilloscope or other USB source. The maximum input voltage range is up to ± 600Vpp.

The ISFE is an invaluable addition to any oscilloscope in situations where measurements are to be made with different ground references, or on floating systems where a ground connection through the oscilloscope is undesirable. A typical application is one probe measuring CAT II mains voltage across live and neutral, the other probe measuring a low voltage DC signal in a system powered by line voltage. Using an ISFE means that you are not restricted to measurements referenced to ground.
