Oscilloscope-preamplifier


Posted on Jun 10, 2012

This circuit provides about 20 dB voltage gain with a frequency range from 0.5 to 50 MHz. You can extend tbe low-frequency response of this circuit by increasing tbe value of the 0.05-ILF capacitor- or try removing tbe capacitor. This circuit delivers a particularly small level of input noise, measured at approximately 20 p.V over a bandwidth range of 15 MHz.

Calibrate the gain by adjusting tbe gain potentiometer connected between pins 3 and 10, tben adjust the 1-KO trimmer potentiometer for an exact voltage gain of 10; this helps preserve the -vee· -svoc scale factor of the oscilloscope.
