REMP-128 Receive EMAT Matching Network
The REMP-128 consists of eight capacitors, which may be switched in parallel with a receiving electromagnetic acoustic transducer (EMAT). Resonating the EMAT coil is usually quite effective in raising the impedance and reducing the bandwidth. The low-noise pre-amplifier also plays an important role in preserving the signal-to-noise ratio. Power is usually supplied by a RAM system.
