The | 560-series plug-ins are designed to drive the [[CRT]]'s deflection plates directly. The impedance seen by the differential | ||
signal of the plug-in looking into the mainframe is typically 14.3 pF and has no resistive component. The mainframe | |||
contains trimmer capacitors to standardize this capacity. | |||
The deflection sensitivity of the mainframe to differential deflection signals at the plug-in connector is about | |||
19.5 V/div for the vertical and 18.5 V/div for the horizontal plates. The sensitivity is not standardized, it depends | |||
on the CRT and high voltage. This means that when plug-ins are swapped between mainframes, they | |||
need to be recalibrated. | |||
