The Tektronix 564 is the storage scope of the 560 series, introduced in June 1962. It takes two 2- or 3-series plug-ins. The RM564 is the rack-mount version.

The 564 is a tube-based oscilloscope, whereas a later version, the 564B (1969), is fully solid state. MOD121N added auto-erase. The screen has bi-stable storage in two 4 cm × 10 cm sections, allowing independent saving and erasing of the upper and lower half.

The 564 was one of the mainframes offered for the Engine Analyzer package.

Steve Ditter says:

Tek offered two phosphors for the 564. You can determine which one you have by reading the CRT part number, visible in the window in the shield where the deflection plate connections are. 154-0410-00 is P200, which was the standard tube. The 154-0418-00 is the P201, which has faster writing rate, but at the expense of about 30% shorter useful life.



As in all 560 series scopes, the left plug-in directly drives the vertical deflection plates of the CRT, and the right plug-in directly drives the horizontal deflection plates.


The 012-0102-00 Storage Oscilloscope Control Unit that works with the 549 also works with the 564B but not the 564. It provides (corded) remote reset of the sweep and independent erase of the upper and lower storage areas.
