This circuit is intended for use with common oscilloscopes having been found in documentation on instrumentation from the 1970s. The capacitors are of the ceramic type with low parasitic inductance.
In the figure we have a way of obtaining a 13,2 V with current up to 5 A using an integrated 7812...
This circuit generates signals controlled by crystal and can generate marks up to 30 MHz of 1 in 1...
This is a typical common collector amplifier step configuration. The transistor can be used...
