* 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.

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. The 564B manual says:<blockquote>

The accuracy of measurements made with the Type 564B depends on the calibration of the plug-in units used.

Since the plug-in units drive the deflection plated directly, each unit must be adjusted to match the deflection sensitivity of the particular CRT it drives.

Therefore, the gain or sweep timing adjustment must be checked each time a plug-in unit is changed.

On most units, gain or timing calibration is made with a front-panel screwdriver adjustment.

</blockquote>

* 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.
