Kari Mäki 9.4.2013 1(7) AC3200 INTELLIGENT BROADBAND AMPLIFIER AC3200 is the latest leading-edge addition to AC family with extended frequency and gain ranges and integrated electrical controls in both up- and downstream. It provides two active outputs with individual signal controls. AC3200 has automatic alignment routines, which take care of optimized SNR performance of both signal directions. ALSC circuits are built-in and they can activated easily by adding the transponder unit. Both signal paths are equipped with a universal plug option. These slots are protected against service interruptions with automatic Non-Stop function. Upstream signal path has many benefits compared to average products on the market. There is an extremely high gain with output and mid-stage gain controls. Signal level or unwanted disturbances like CPD or ingress can be monitored even in the cases when return channel is switched off. The local USB interface enables local control through PDA or laptop. Remote control is possible via either CATVisor or HMS compatible transponder. Features 1 GHz bandwidth Remote power supply with PFC 2 active outputs Intelligent continuous adjustments with huge gain control range Local control with PC or PDA through USB connection Possible to order customized pre-settings GaAs FET amplifier technology Excellent ESD and surge protection With AC6991/AC6980 transponder plug-in: CATVisor / HMS (AC6991) or DOCSIS (AC6980) remote connection ALSC with fully user programmable pilots Downstream spectrum analyser Upstream signal quality monitoring with automatic ingress control True plug-and-play with single pushbutton alignment Return path pilot generator (AC6991)

Kari Mäki 9.4.2013 3(7) Notes 1) The limiting curve is defined at 40 MHz -1.5 / octave. 2) Step size is 1. 3) Step size is 0.2. This interstage control is used in ALSC operation. It typically works up to - 15, but range between -13-15 has no guaranteed performance. 4) Between 47 862/1006 MHz. Step size is 1. Pivot frequency can be selected electrically. 5) Between 47 862/1006 MHz. Pivot frequency can be selected electrically. 6) Typical value. The guaranteed value is ± 0.75. Flatness is defined with diplex filters. All other used plug modules are 0 pads. Spec is valid 2 MHz after the starting frequency of the selected diplex filter. 7) Typical value for 4.43 MHz band. Measured at channel S2. 8) Output TP has a tolerance of ± 0.75 between 47 862 MHz and ± 1.0 between 862 1006 MHz. It is defined with 0 plug as OUTPUT MODULE 1. Input TP is transformer type with ±1.5 tolerance. 9) Level difference between transponder connection and output 1. Tolerance ±0.5. 10) Typical value at 862 MHz with the maximum gain. The guaranteed worst case value is 1.0 worse. 11) Typical value according to IEC60728-3-1. Channels have 10 cable equivalent slope between 110 1006 MHz and signal level has been defined at 1002 MHz. BER measurement has been done on the worst channel between 110 862 MHz. 12) EN50083-3. Amplifier output was 8 cable equivalent sloped. All results are typical values in room temperature. XMOD is measured at the lowest channel. The highest recommended output level for the amplifier is 112.0 uv with 42 channels. 3.0 2.0 1.0 0.0-1.0 CTB level -2.0 CSO level NF -3.0 0 2 4 6 8 10 Mid-Stage Attenuation The picture is showing how the NF and distortion performances are changing if mid-stage gain control is used. Defined with the 8 sloped output and CENELEC loading. Performance is defined at the worst frequency. 13) Measured with 77 and 110 NTSC channels. Amplifier output was 12 linearly sloped and the used levels were at 55 / 550 / 750 / 862 MHz 35.0 / 42.5 / 45.5 / 47.0 mv. All results are typical values in room temperature..

Pivot frequency is 65 or 85 MHz, which can be selected electrically. 16) Typical value. The worst case value is ± 0.6. Flatness is defined with 65 MHz diplex filters. 17) This is the level difference between return path input and transponder transmit pin when return path is set to full 30 gain. This value increases linearly to -17 when return path gain decreases to 20, after that it stays at -17. The accuracy is ± 1.
