A transmitter, a fiber, a receiver

The FO-HBST transmitter and the FO-HBSR receiver carry one analog voltage, from DC to 1 MHz, over a fiber-optic cable. Connect either module to the device under test to monitor a signal or to source one. The other module sits at the remote end.

A 3-position slide switch on the transmitter sets the full-scale input to ±8 V, ±16 V or ±48 V. The receiver outputs up to ±16 V whatever the input range. Each module runs on 3 AA batteries or an external power adapter.

Shielding and input and output filtering protect both modules from EMI, EMP and the high voltages of plasma research. They are validated for EMC up to 200 V/m from 500 kHz to 18 GHz, and 600 V/m pulsed (5 % duty cycle, 5 µs rise time) from 1 to 2.5 GHz.
