• Notes
• 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.
  
  The 7A18 with option 6 is equipped with added DC offset circuits that provide up to ±200 divisions of baseline offset within the input dynamic range, with uncalibrated front panel variable controls for each channel. The variable controls are concentric with the position controls, replacing the IDENTIFY pushbuttons formerly used on the unmodified unit.
