SCOPE_SENSITIVITYAMPLIFIER

This circuit provides 20 ±0.1 dB voltage gain from 0.5 to 25 MHz and ±3 dB from 70 kHz to 55 MHz. An LM733 video amplifter furnishes a low input-noise spec, 10-μV typical, measured over a 15.7-MHz bandwidth. The scale factor of the instrument can be preserved by using a trimmer R1 or a selected precision resistor, to set the circuit's voltage gain to exactly 100.
