t of one of four scope preamps (Q1/Q2 through Q7/Q8) and feeds it to buffer Q9 and output jack Jl. J2 provides synch to the scope. R20 through R23 are posting controls for channels A through D (J3 through J6). SlA-B through S4A-B are switched attenuators, one for each channel. Switching rate is about 125 kHz. This circuit is useful for adding four-trace operation to inexpensive oscilloscopes. Signal levels of 0 to 20 V can be handled.
