QMOD-HD
Specifications
Physical
Size: 8.5” [216mm] wide x 1.75” [44mm] height (1RU) x 6.0” [153mm] deep
Weight: 1.5 lbs [0.68kg]
Temperature: +32° to 122° F operating temperature, convection cooled
Mounting: Rack mounting for one or two units side-by-side optional (RK1, RK2)
Front Panel
Setup, Select and directional buttons for front-panel setup
Menu LCD, 2 lines of 20 blue characters each
Encoding
MPEG2 Profile: MP@HL for HD, MP@ML for SD
1080i, 720p, 480p, and 480i resolution, depending on input
Video Encoding bitrate 13, 15, 18, and 25 Mbps
MPEG1, Layer 2 audio
Modulation
Switchable 64/256 QAM, J83 Annex B, Interleaving Modes (128,1)
MER 38 dB typical
Latency
Compliance
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.
FCC Class B, ROHS, meets California standards
Power
2.1mm coaxial jack (inside center conductor positive)
0.7 A maximum, 11.5 to 13.5 VDC, 12 VDC typical
