 The Tektronix 3A1S is a vertical plug-in for the [[561#561S|561S]].
-It is specified to have an input impedance of 47pF in parallel with 1 megohm.
-Input sensitivity in a 561S is from 10mV/div to 10V/div.
-Risetime is specified to be 14ns, giving a -3dB frequency of 25MHz.
 The input signal passes through a compensated attenuator switch and
-then into a [[7586]] cathode-follower biased with 2mA plate current.
+then into a [[7586]] cathode-follower biased with 2 mA plate current.
