The Tektronix A6907 / A6909 High Voltage Isolators connect “floating” (not referenced to ground) signals to an oscilloscope or digitizer for measurement.
The A6907 has four, the 6909 has two input channels.
The A6907/A6909 include special probes with an in-cable balun for shielding against large dv/dt fields. These probes are specific to the A6907/A6909.
Optionally, an A620 current probe can be connected.

Internals
Optical couplers, insulated transformers, and plastic barriers are used for extremely high isolation between channels and the chassis, and from channel to channel.
An electrical-to-optical (E/O) converter isolates the signal and converts it to an optical analogue. An optical-to-electrical (O/E) converter demodulates the optical signal to an electrical signal whose common mode elements have been rejected. The E/O converter uses a low-contact DC to DC converter as a power source to provide a high degree of isolation.
