The FAxM Series is a professional quality, multiple channel agile audio/video modulator. This unit provides audio and video modulated RF carriers on any channel in the 54 to 860 MHz frequency range, using only one rack space. Any standard audio/video source can be used, such as satellite receivers, television cameras, video tape recorders, or television demodulators. Agile channel selection permits on the-fly channel changes and reduces the need for large inventories of channelized products. Four modules are available with 2 basic distinctions. NOTES (a) continuously adjustable (b) 4 MHz bandwidth, +50 dBmV output, 3 channels combined (c) meets FCC CATV group delay pre-distortion requirements for color transmission (d) 87.5% depth of modulation (e) for 25 kHz peak deviation (f) available via internal jumper setting (g) referenced to standard 75 µs pre-emphasis (h) 30 Hz to 15 kHz, 25 kHz deviation (i) 0 °C to +50 °C (k) continuously adjustable, optimum performance at +40 to +50 dBmV (l) AC current with 3 modules installed
