The Pulsar MKII (DK) is an intelligent agile analog television modulator that converts baseband video and audio signals into RF output for cable network distribution. It features microprocessor control, remote configuration via ROSA NMS, automatic RF level adjustment, and a front-panel LCD interface.
Key specifications include a 45-870 MHz frequency range, RF output level of 50-61 dBmV, video input of 1 Vpp, audio input of -10 to +10 dBm, and SAW filtering for adjacent-channel performance. Options include a second video/audio input with AGC, stereo encoding, scrambling interfaces, and a -48 V power supply. The unit operates from 0 to 45°C, consumes up to 40 W, and fits in a 1RU 19-inch rack. This manual is written in Chinese.
