The Tektronix 154-0644-xx (P/N 154-0644-05, 154-0644-09) is a CRT with distributed deflection plates for instruments specified up to 500 MHz. Suffix -05 has green P-31 phosphor, suffix -09 has blue P-11 phosphor.
A domed scan-expansion mesh between the deflection plate structure and the accelerating anode provides both isolation and a two-times deflection magnification.
Typical acceleration voltage is 24 kV (−3 kV on cathode, +21 kV on post-acceleration anode).
As used in the 7904, the 154-0644-05 CRT has a deflection factor of 3 V/div and an impedance of 385 Ω.
