-The mainframe communicates with the plug-ins via the Serial Data Interface (SDI).
+The mainframe communicates with the plug-ins via the [[SDI|Serial Data Interface (SDI)]].
-SDI was designed by [[Lester Larson]].
-This communication bus comprises three signals:
-* SDI clock
-* SDI mainframe to plug-in
-* SDI plug-in to mainframe
-On the mainframe side, this communication is controlled by the U1760 SDI IC
-(Tektronix part number 156-2622-00) on the A11 Main Processor board,
-which is at the top rear of the scope.
-The 11301 SDI is a synchronous serial interface.
-The clock signal, which is generated by the mainframe,
-is 5V TTL, 4 MHz, constantly running.
 The 11300 performs a variety of self-checks and self-calibration.
