4.2 STORAGE DISPLAY VTOIA
The VT01A is a Tektronix Model 611 direct-view storage tube with a resolution of
400 stored line pairs vertically and 300 stored line pairs horizontally. Dot writing
time is 20 ps, with a full screen erase time of 500 ms_ The VT01 can display
30,000 discrete resolvable points.
The VT01A is interfaced to the UNIBUS and controlled via the Mll-A and MIl­
D conversion subsystem (see Chapter 9).

4.3 OSCILLOSCOPE VR01A
The VROIA, a modified Tektronix type Rm504 oscilloscope, provides accurate
measurements in DC-to-450 kHz applications. It is a low-.frequency, high sensitivity
display and can be used for accurate curve plotting in the X·Y mode of oper·
ation_
