Signal preamplifier PR-06-04

four-channel

The PR-06-04 is a four-channel pulser/preamplifier for pulse-echo. Each channel can drive a conventional UT probe for a higher gain pulse and boost the return signal, thereby improving detection and signal-to-noise ratio. The PR-06-04 can also be used as a pulser or a receiver only. Pulser • -45 V to -220 V input level (min-max) • -160 V to -190 V output amplitude (pulser at 100 ns) • 4 ns to 10 ns rise time and fall time Receiver • 40 dB gain • 8 dBm to 12 dBm input level (max.) • 8 dBm to 12 dBm output level operation • 550 kHz to 30 MHz bandwidth at -3 dB
