Test Equipment: PCI QAM (Clear QAM) and PCI 8VSB Modulator Cards

Home >> Test Equipment >> PCI card Modulators typically used in North America on cable systems and "over the air"

Frequency agile (55-810 Mhz) "US clear channel" or DVB-C QAM 16/32/128/256 modulator with field upgradeability to other modes. Not compatible with SA or Motorola QAM STB's since they have proprietary signaling. PCI half-card with transport stream input via PCI bus or external input via BNC connector on bracket. IF and RF output targeted at only STB Testing, Digital Signage, and Laboratory Applications. Ships with Windows XP based Transport Stream Player. This device can feed either an antenna or coax cable.

Frequency agile, Field upgradeable with other modes, VHF/UHF 8VSB modulator. PCI half-card with RF out on BNC connector. Pulls transport streams from HD via PCI bus or from external devices from BNC connector on bracket. Both IF and RF output targeted at Digital Signage, STB Testing, and Laboratory Applications. Auxiliary ASI out for checking TS data flow. Ships with Windows based Transport Stream Player. Linux and Windows SDK available for customization. This device can feed either an antenna or coax cable.

Frequency agile, Field upgradeable with other modes, 2 independent RF channel, VHF/UHF 8VSB modulator. PCI half-card with RF out on BNC connector. Pulls transport streams from HD via PCI bus or from external devices from BNC connector on bracket. Both IF and RF output targeted at Digital Signage, STB Testing, and Laboratory Applications. Auxiliary ASI out for checking TS data flow. Ships with Windows based Transport Stream Player. Linux and Windows SDK available for customization. This device can feed either two antennas or two coaxial cables.

Standard Features:

• DVB-ASI or SMPTE 310M transport stream input via mini ASI connector or included BNC header
• When ASI is input the TS can be any rate since it is upconverted and remuxed to ATSC rate
• When DVB is input the bit rate can be anything above 2 Mbps or below 19 Mbps
• ASI in via PCI or from bracket connector
• Can be reprogrammed to add QAM, QPSK, DVB-T, and I-SDBT to the card
• 44MHz/36MHz IF output or on board Channel 2~69 selectable RF output up-converter
• Supports EIA 50-860 MHz Band
• ECC: Reed Solomon(204,188,T=8) encoding
• 8VSB: 2/3 Rate Trellis Coding Conforming to ATSC A.53 specs. Symbol Rate Fixed at 10.7622 Symbol/Sec
• Freq Config GUI supported via Win XP and Linux
• Customer oriented API is also available
• CMI can supply sample transport streams
• Power output adjustable from -25 to 0 dBm

Each modulator card can be licensed for
additional profiles upon payment of a license fee... Any card can have one, a few, or many profiles.

Profiles available are:

QAM, DVB-C, QPSK, DVB S, DVB-S2, 8VSB, T-DMB, DVB T+H, ISDB-T

Real time mixer for multiple VHF or UHF Modulated signals onto a single coaxial cable. These products come in combiners for 1-8 channels and are also available from Radio Shack or R.L. Drake.
