Page 3: Overview
7700 MultiFrame Manual 7700ADA7 Analog Video Distribution Amplifier OVERVIEW The 7700ADA7 Analog Distribution Amplifier is a general purpose amplifier for distributing analog video signals. The 7700ADA7 features one balanced input with seven outputs. The 7700ADA7 amplifier has been designed to distribute a wide range of analog video signals. It can also distribute other pulses and signals that are less than 2Vp-p. -
Page 4: Installation
7700 MultiFrame Manual 7700ADA7 Analog Video Distribution Amplifier INSTALLATION The 7700ADA7 comes with a companion rear plate that has 8 BNC connectors. For information on mounting the rear plate and inserting the module into the frame see section 3 of the 7700FR chapter. Figure 2-1: 7700ADA7 Rear Panel ANLG IN: Input (isolated) BNC connector for analog video signals. -

7700 MultiFrame Manual 7700ADA7 Analog Video Distribution Amplifier SPECIFICATIONS Note: At the time of printing, this product has only been qualified for use with standard definition signals. It, however, has been designed to work with high definition signals. Frequency and phase response will not be optimized at the upper frequency range of high definition video bandwidths. -
Page 6: Status Leds
7700 MultiFrame Manual 7700ADA7 Analog Video Distribution Amplifier STATUS LEDS The 7700ADA7 has two LED Status indicators on the front card edge to show operational status of the card at a glance. Figure 6-1 shows the location of the LEDs. Two large LEDs on the front of the board indicate the general health of the module. -

SELECTING WHETHER LOCAL FAULTS WILL BE MONITORED BY THE GLOBAL FRAME STATUS The FRAME STATUS jumper J1, located at the front of the module determines whether local faults (as shown by the Local Fault indicator) will be connected to the 7700FR frame's global status bus. -
Page 8: Gain Adjustment
7700 MultiFrame Manual 7700ADA7 Analog Video Distribution Amplifier 6.4. GAIN ADJUSTMENT The GAIN POT on the cards front edge allows the user to adjust the input signal level. Turning the POT clockwise will increase the gain. There is enough range on this control to counteract the video level error due to a missing or double terminated coaxial connection.
