Description
The MSC models FO-HBST and FO-HBSR form a versatile Fiber-Optic Analog Signal TX/RX pair that provides a means to transmit wide bandwidth electrical signals over fiber-optic cables to/from remote sources in high electromagnetic fields or anechoic chambers to/from monitoring equipment in low field areas.
Both transmitter and receiver are EMI hardened and validated for EMC up to 200 V/m (46 dBV/m) at 500 kHz to 2 GHz. The transmitter monitors analog signal inputs at bandwidths from DC to 1 MHz. High 'Z' input leads and EMI filtering ensure EMC compatibility without compromising signal integrity. Selectable gain jumpers are used to configure the transmitter modules for full-scale input levels of ±4, ±8, ±16, and ±48 VDC. Likewise, selectable gain jumpers are used to configure the receiver modules for full-scale output levels of ±4, ±8, and ±16 VDC. Systems may also be configured to user defined full-scale inputs and outputs.
Each TX/RX module is powered with 3 standard 'AA' alkaline batteries and is able to operate in excess of 16 continuous hours before replacing batteries. Alternately, each module can be powered using the supplied external power adapter.
The FO-HBST/HBSR use multimode 62.5/125 μm or 100/140 μm fiber cables. ST type connectors are standard.
