Single-beam tube 11LO9I (11LO-9I, 9I 11LO, 11L09I, 9I-11L0, 11L0 9I)

Single-beam tube 11LO9I posleuskoreniya with a single stage, with blanking plates with a rectangular screen with a flat surface and the scale of reference parallax. 11LO9I single-beam tube is designed for visual observation and measurement of electrical processes in the electronic devices. Emission color screen - green. The size of the working of the screen 60X80mm. The focused line width not more than 0.6 mm.
Conclusions electrodes 1, 14 - heater 2 - shielding plate 3 - cathode 4 - modulator, 5 - a fourth anode, 7, 8 - temporary deflection plate X 1, X 2, 10 - the first anode (focusing) 12 - third anode (focusing), 13 - second anode (accelerating), the signal deflection plates Y 1, Y 2 - lateral plugs on the cylinder, and A - the fifth anode, 6, 9, 11 - do not connect. Making - wedge base glass with additional findings on the cylinder. Weight 0.6 kg.
