Specifications
Typical deflection factors are 1 V/20 cm horizonal, and 1 V/15 cm vertical. Beam settling time (within 0.025 cm) is specified to be 14 μs + 6 μs per cm of deflection, for spot movements up to 2 cm. For larger spot movements, the settling time is 3 μs per cm. The stored resolution is 200 x 266 line pairs. Erase time is approximately 0.9 seconds.
The 613 consumes 180 watts and weighs 19 kg (43 pounds).
