C6-1 Agile Heterodyne Processors AP Series

C5-1 AP Series Agile Heterodyne Processors

The AP Series includes professional quality, agile heterodyne processors equipped with the Emergency Alert System (EAS) feature, which can also be used as an alternate IF input. These units convert any channel in the 50 to 806 MHz (7 to 43 MHz with Option 17) frequency range to any channel in the 50 to 450/550 MHz (7 to 450 MHz with Option 04) frequency range. The AP Series is ideal for moving an off-air channel (VHF or UHF) or any single channel source to any unused channel (broadcast or CATV, including HRC and IRC assignments) in the system. Agile channel selection permits on-the-fly channel changes and reduces the need for large inventories of channelized products. These processors have a wide range of standard and optional features that make them very suitable for advanced CATV systems. Four models are available, including: AP-40-450, +40 dBmV, 50-450 MHz; AP-40-550, +40 dBmV, 50-550 MHz; AP-60-450, +60 dBmV, 50-450 MHz; and AP-60-550, +60 dBmV, 50-550 MHz. All models feature rock solid, synthesized frequency control, with a tuning increment of 250 kHz. Frequency selection is accomplished via front panel DIP switches. A channel listing chart is conveniently attached to the inside of the DIP switch cover. True vestigial sideband SAW filtering guarantees superior broadcast picture quality. Two SAW filters are used to ensure proper adjacent channel rejection. Delayed AGC circuitry automatically compensates for input signal variations. These processors have an external IF loop, which allows interfacing with video all-call and signal scrambling systems. The AP Series utilizes a standby carrier oscillator to provide a blank picture when the input level drops below a usable level. This prevents a snowy picture from being delivered to the distribution network in the event of signal degradation or complete loss of picture.

The EAS/ALT IF feature allows the customer to choose between manual and automatic selection of EAS/ALT IF input signal. This is done through a 3 position terminal strip on the rear of the unit. In the manual mode the EAS/ALT IF feature is activated by a contact closure switch, which completes a ground connection. In the automatic mode two positions on the terminal strip are jumpered together enabling an automatic detection circuit in the unit. When an EAS/ALT IF signal is routed to the EAS/ALT IF port the unit automatically switches to that alternate signal. These processors provide extremely clean output signals with distortion products (-60 dB or better). An exceptionally low broadband noise floor (-76 dBc or better) makes the AP Series ideal for large, multiple channel headends without the need for additional filtering.

OPTIONS:

AP-OPT 12 59122 AP Series Option: Automatic Broadcast Offset Correction NOTE: AP Unit must be ordered

AP-OPT 14 59144 AP Series Option: On Channel-lock NOTE: AP Unit must be ordered

AP-OPT 17 59177 AP Series Option: Sub-Band Input, 7-49 MHz NOTE: AP-60 Unit must be ordered

AP-OPT 20 59200 AP Series Option: Digital Control, Serial RS-232 NOTE: AP Unit must be ordered

NOTE: Multiple options may or may not be installed in a single unit. Please consult Blonder Tongue factorybefore ordering options.

OPTION 04 - Sub-band Output This option provides frequency coverage from 7 to 450 MHz (AP-60-450).

OPTION 12 - Automatic Broadcast Offset Correction (ABOC) This option provides automatic compatibility with broadcast and cable frequency offsets, removing any frequency offset (up to ±30 kHz) from the input channel. The output channel can then be set to comply with FCC aeronautical offset requirements via a front panel DIP switch (either 0, +12.5, or +25 kHz offset).

OPTION 14 - On Channelock This option eliminates picture flutter and moire patterns that occur when using the processor with the same input and output channel in the presence of strong broadcast signals.

OPTION 17 - Sub-band Input This option provides extended frequency range for sub-band input channels (T7 through T13). A rear panel switch allows configuration of the processor for standard VHF/UHF (50-806 MHz) channels or sub-band (7-49 MHz). When invoked, this option block converts the sub-band channels to VHF channels 7 through 13 (selecting input channel VHF 7 will select sub-band channel T7).

OPTION 20 - Digital Control, Serial RS-232 This option accepts a serial RS-232 data input to change the output frequency of the processor, enable/disable the video, select frequency plans (standard, HRC, IRC) and determine the status of the processor (frequency, video,frequency plan).
