Introduction The R7704 features a CRT with small spot size
and high writing speed. Graticule area is 8 X 10
The Tektronix R7704 Oscilloscope is a solid- centimeters. In addition, the instrument contains a
state, high performance instrument designed for readout system to provide CRT display of alpha-numeric
mounting in a 19-inch rack (complete rackmounting information from the plug-in units; data such as
information is given in Section 6). This instrument deflection factor, sweep rate, etc. can be encoded.
accepts Tektronix 7-series plug-in units to form a
complete measurement system. The flexibility of this This instrument will meet the electrical
plug-in feature and the variety of plug-in units available characteristics listed in Table 1-1 following complete
allow the system to be used for many measurement calibration as given in Section 5. The performance
