Bandwidth is dc to at least 1 MHz.CRT AND DISPLAY FEATURESStandardInternal 8 X 10 cm graticule with variable illumination. Accelerating potential is 24 kV with P31 Phosphor standard.Option 01, without CRT readoutNo CRT readoutOption 04, Max Brightness CRT With Reduced AreaInternal 4 X 5 cm graticule with variable illumination. Accelerating potential is 24 kV. P11 Phosphor provides max writing rate. This provides extremely high photographic and information writing speed and increases the visibility of low-rep-rate, high-speed signals.Option 78, P11 PhosphorMinimum Photographic Writing Speed Using the Optional P11 and Polaroid 3000 ASA Film without Film FoggingPolaroid FilmRelative Writing SpeedASATypesWithout FoggingWith Fogging3000107 084 471 (reference)31000041024In typical applications, P31 Phosphor has approximately one-half the writing speed of P11 Phosphor. The writing speed can be increased by using controlled film fogging with a writing speed enhancer (camera accessory) or by using Polaroid 10,000 ASA film or both. The following table lists the approximate relative writing speed gains that can be achieved using these techniques.Polaroid FilmRelative Writing SpeedASATypesWithout FoggingWith Fogging3000107 084 471 (reference)31000041024AutofocusReduces the need for additional manual focusing with changes in intensity after focus control has been set.Beam FinderLimits display within graticule areaExternal Z-Axis Input2 V p-p for full intensity range.
