The Tektronix 7A18 is a Dual Trace Amplifier compatible with all Tektronix 7000 Series Mainframes.
The 7A18 Dual-Trace Plug-In Amplifier is the basic building block of 3-trace and 4-trace operation. The unit features constant bandwidth for all deflection factors, 5 operating modes (Ch1, Ch2, ALT, CHOP, ADD), trigger source selectivity and color-keyed control grouping. Features include: Bandwidth: DC to 75MHz; Trace Identify Function; Polarity of Channel 2 is selectable; Deflection Factor: 5 mV/div to 5 V/div; Input R and C: 1 Mohm within 2%; approx. 20 pF
