Specifications
8.5” [216mm] wide x 1.73” [62mm] height (1RU) x 6.0” [153mm] deep
1.5 lbs [0.68kg]
+32° to 122° F operating temperature, convection cooled
Rack mounting for one or two units side-by-side optional (RK1, RK2)
Power button
Select and directional buttons for menu setup
Menu LCD, 2 lines of 20 blue characters each
MPEG2 Profile:MP@HL for HD, MP@ML for SD
1080i, 720p, 480p, and 480i resolution, depending on input
Video Encoding bitrate 18 or 25 Mbps
MPEG1, Layer 2 audio
Latency: 360 ms@720p, 660ms1080i, includes all processing and tuning.
HDTV modulators experience more latency, as the media is converted to
MPEG2 and QAM, then distributed over RF.

MER 38 dB typical
RF Output
Agile, channels 2-135 (48-860 MHz), standard, HRC, or IRC spacing
6 MHz bandwidth fits any open channel without interference to adjacent channels
1 KHz resolution, +/- 30 ppm accuracy, +/- 35 ppm stability
29 dBmV typical output power, attenuated in 5 steps, approx 4 dB
