Vertical input signals from the BNC inputreceptacle enter the first-stage attenuator circuit, along the path selected bythe AC-GND-DC switch. Then they pass through either attenuator 1/1, 1/10, or1/100, along the path selected by the vertical rotary switch, and become inputinto the 1st preamplifier (first-stage buffer amplifier).

The 1st preamplifier consists ofU1 and Q1 (CH2 : U2 and Q2). The elementused for U1 features a wide dynamic range and minimized temperature drifting.U1 functions in the preamplifier as a circuit in which temperature drifting isconsidered. Input signals, impedance converted in this buffer amplifier, arcsent to the second-stage attenuator where they are passed through eitherattenuator 1/1, 1/2, 1/4, or 1/10. They are then sent to the verticalamplifier. The second-stage attenuator constitutes a low impedance resistancenetwork with favorable frequency characteristics. The resistors used, as isthose of the first-stage attenuator, have a precision of 0.5% for minimizingany error between the steps of the attenuators. The rotary switches in thisstage include one which increases the gain of the preamplifier to 5-fold whenthe sensitivity is 1 mV/div or 2 mV/div.
