264. Gain Control Setting (AGC)Select an automatic gain control mode. This setting raises the gain and brightens the image under low light conditions. Thedefault setting is "ON (HIGH)".Available modes: ON (HIGH), ON (MID), ON (LOW), OFF5. Electronic Sensitivity Enhancement (SENS UP)Select a proper enhancement rate when the camera is set to ALC mode. The higher rate you select, the brighter the picture willbe. The default setting is "OFF".AUTO: Sets "AGC" to "ON" and adaptively raises the sensitivity up to the selected amplification rate, for example 10 timeswhen set to "X10 AUTO".FIX: Raises the sensitivity fixedly to the selected rate.OFF: Does not raise the sensitivity.X2 AUTOOFF X4 AUTO X6 AUTO X10 AUTOX32 FIX X10 FIX X6 FIX X4 FIX X2 FIXOFFX16 FIXSUPER-D3 OFF:X2 AUTOOFF* X4 AUTO X6 AUTO X10 AUTOSUPER-D3 ON:* DefaultNotes:• Some types of system controllers may not operate some of the SENS UP functions. If this happens, use the operation but-tons on the camera.• When you select "AUTO" for "SENS UP" and "ON" for "SUPER-D3", the SENS UP function has priority so that the SUPER-D3function is not activated automatically.• While the SENS UP function is selected, noise, spots or a whitish phenomenon may appear in the picture when the sensi-tivity of the camera is increased. This is a normal phenomenon.• Only when "OFF", "X2 FIX", or "X2 AUTO" is selected for sensitivity enhancement (SENS UP), it is possible to perform ABFadjustment or to select "AUTO" for "C/L ←→ B/W" on the "BACK-FOCUS SETUP" menu. When a sensitivity rate other than"X2 FIX" or "X2 AUTO" is selected, use "PRESET" and "FIX" for "C/L ←→ B/W" on the "BACK-FOCUS SETUP" menu.6. Synchronization Setting (SYNC)1. Select a sync mode.VD2: Multiplexed vertical drive, highest priorityLL: Line-Lock, follows the phase of supplied AC power, 2ndpriorityINT: Internal sync, lowest priorityNotes:• Selection is not available when VD2 is added to the camera.Selection from "LL" is available when the respective sync isadded.• When "LL" is selected, phase adjustment is required.2. Line-Lock Vertical Phase Adjustment (V PHASE)• Select "LL" and press the [SET] button.• Prepare a dual-trace oscilloscope and supply it with the video output of the camera to be adjusted and that of the refer-ence camera.• Set the oscilloscope to the vertical rate and expand the V-sync portion.• Select a proper "COARSE" phase from 16 steps (22.5 degrees/step) that makes the two video signals on the oscilloscopethe closest.**SYNC**V PHASECOARSE 1(1--16)FINE ...I...128- +RET TOP END
