* Checking calibration after changing plug-ins is recommended. The signal path of the plug-in to mainframe interface is not as well standardized as it is on [[500-series scopes]] or [[7000-series scopes]]. This is primarily due to variability in deflection sensitivity of CRTs. | * Checking calibration after changing plug-ins is recommended.

* Since each plug-in contains deflection amplifiers, 560-series plug-ins cost more than a plug-in with equivalent functionality for a mainframe that has built-in deflection amplifiers. The cost of the deflection amplifiers adds up if the customer wants several different plug-ins at the high-speed end of the 560-series range. | * Since each plug-in contains deflection amplifiers, 560-series plug-ins cost more than a plug-in with equivalent functionality for a mainframe that has built-in deflection amplifiers. The purchase cost, weight, and maintenance burden of the extra deflection amplifiers adds up, particularly if the customer wants several different plug-ins at the high-speed end of the 560-series range. | ||
