Catcast Technology Co., Ltd. (Chengdu)  

Product Name: DVB- (T) with Asi and IP Input Modulator with RF out Model NO.: HPS8502 Condition: New Certification: CE, ISO, RoHS, SGS,FCC Function: Signal Transmission Equipment Type: CATV?Cable Television?Equipment Trademark: CatCast Transport Package: Carton Specification: 1U Origin: Chengdu, China Product Description DVB-(T) with Asi and IP Input Modulator with RF outOutlineHPS8502 (HPS8502A) DVB-(T) modulator is our new product developed complying with the DVB-(T) standard. With itsadvancedmodulatingtechnology, this modulator can effectively make use of the ground spectrum resourcesand make it possible to provide reliablesignals for fixed, mobile and portabledevices.Comparedwith DVB-T, the channel capacity is increasedby 30% under the similarcarrier to noise ratio (CNR) threshold. HPS8502 (HPS8502A) DVB-(T) modulator also supports single-PLPand multi-PLP (option) to receive T2-MI from DVB-(T) gateway through its ASI and IP port. (This function is also option.)Moreover, this device can be upgraded and controlled through network system, which allows it tobe widely used in setting up digital broadcasting networkand provide good signals for scientificlaboratory andDVB-(T) STB.FeaturesFully complying with EN302 755 standard4ASI inputports (for 1 channel TS input with 3 ports for backup)TS over IP input (UDP); T2-MI over IP input(Option)10MHz input/loop out, 1PPS input/loop outDVB-(T)RF outputSupports single PLP, multi-PLP (Option)Support MISOand SISOSupport QPSK/16QAM/64QAM/256QAM(normalor rotated)Support TS format: T2-MI(Option)or TS (Mode A)High performance output: MER>43dB, shoulder level>56dBOutput signal bandwidth: 5M,6M,7M,8MHzSupport MFN and SFN (Option) net modeSupportsnon-linear and linear digital pre-distortion(DPD)RF output level: -25~+3 dBm, 0.1db steppingConstant temperature crystal oscillator, as high as 0.1ppm stabilitySupport online upgradeKeyboard operation and LCD displayWeb Network management system (GUI)SpecificationsInputT2MI input over ASI and IP(Option)1000 Mbps Ethernet port----HPS8502A100 Mbps Ethernet port----HPS8502TS input over ASIand IP port (UDP)10MHz reference clock inputand loop out, BNC interface1PPS inputand loop out, BNC interfaceModulationStandardEN302 755ModeMode A: single-PLP; Mode B: multiple-PLP(Option)PLP ConstellationQPSK, 16QAM, 64QAM, 256QAM(Normal orRotated)L1 Post ConstellationsBPSK, QPSK, 16QAM, 64QAMFEC LengthShort(16K), Normal (64K)FEC Rate1/2, 3/5, 2/3, 3/4, 4/5, 5/6Pilot PatternPP1 - PP8Guard Interval1/128, 1/32, 1/16, 19/256, 1/8, 19/128, 1/4FFT Mode1k, 2k, 4k8k, 16k, 32k(normal or extended)Bandwidth5MHz, 6MHz, 7MHz, 8MHzNet Mode MFN, SFN (Option)RF OutConnectorN Type, 50ΩImpedanceRF range30~999Mhz, 1hz steppingOutputlevel ATT-25~+3 dBm, 0.1db steppingMER>43dbShoulder Level>56dBSystemLCD display, keyboard and web Network managementSupporting software upgrading through networkGeneralDemission (W*L*H)482mm×410mm×44mmWeight4.8kgTemperature0~45ºC(operation),-20~80ºC(storage)Power supplyAC 220V±10%,50/60HzPower Consumption34WPrinciple Chart
