This correction is effective even if the signal and hum have been transmitted by microwave, satellite or fiber. An adjustable clamp level allows use with systems that require the sync-tips to be clamped to some level other than -40 IRE (-0.286 volts). The CVB/VDA provides an adjustable gain range of 0.5X to 2.0X and is designed to clamp properly when the output video signal is set to 1Vpp (140 IRE). Frequency Response DC to 120 MHz @ -3 dB (1V pp input) Input Signal 0.5 to 2.0 V pp composite NTSC or PAL video within -1V to +1V range Input Impedance 75 Ohms Input Coupling DC Gain Adjustable (1V pp input) 0.5x to 2.0x Number of Output 4 Output Signal 0.5 to 2.0 V pp composite NTSC or PAL video within -1Vto +1V range Output Impedance 75 Ohms Differential Gain < 0.2%, typically 0.04% Differential Phase < 0.2¨¬, typically 0.08¨¬ Connectors BNC Power Requirements 8-24V DC grounded or ungrounded, 13-24V AC ungrounded, < 100 mA, typically 50 mA Dimensions 3.00¡± W x 0.65¡± H x 2.75¡± (including connectors) Shipping Weight 2 lbs (includes transformer) |
