7B53A

The Tektronix 7B53A and 7B53AN is a 100 MHz dual time base plug-in for 7000-series scopes. It is similar to the 7B52 which is much more rarely found. While the 7B52 has a separate mode switch, this is integrated into the time/Div switch in the 7B53A.

The 7B53AN is electrically identical to he 7B53A but omits the circuits needed to drive the alphanumeric readout system provided in 7000-series mainframes.

X-Y operation

The 7B53 supports X-Y mode by selecting the "Ampl" position on the Time/Div switch. The X signal can be picked up from a vertical plug-in via the internal trigger path or applied via the "Main Trig In or Amp In" input, as depending on the Trigger Source switch setting.
