Product Description

Performance Characteristic
1. Medium frequency treatment technique and dual-phase locked loop technology for CPU control are adopted to improve frequency stability.
2. Number of output channels are within the limit of 48~550/750/870MHz. Standard channels and added channels were installed.
3. Carrier frequency or each channel is within the limit of 48~550/750/870MHz. 4 standards of sound carrier frequency: 4.5, 5.5, 6.0, 6.5MHz.
4. The vision signal modulation, audio deviation, A/V ratio and output level can be adjusted on the front panel.
5. Independent RF Power Amplifiers are inside. The output level is up to over 110dBμ V.
6. It's easier to operate, because of the digital channel number of front panel, the uplink of back panel, memory channels and power failure memory function.
7. Output power of B machine is 48~550MHz. Output power of C machine is 48~750MHz. Output power of D machine is 48~870MHz.
8. Two lines 20-bit LCD display is on front panel. Add medium frequency interfaces.ITEMUNITPARAMETERC78BC 78CC78DRF ParameterOutput Frequency RangeMHZ47_550550_75047_866.25Max Output LeveldBu V≥110≥110≥110Output Level RangedB202010Video/Audio Power RatiodB-13_-20-13_-20-13_-20Out of Band RejectiondB-60-60-65Frequency StabilityKHz333Output ImpedanceΩ757575Output Return LosedB≥16≥16≥16Video ParameterInput LevelVp-p0.7_1.40.7_1.40.7_1.4Differential Gain%≤3@87.5%≤3@87.5%≤3@87.5%Differential PhaseO≤3@87.5%≤3@87.5%≤3@87.5%C/L Delayns≤45≤45≤40Video Modulation DepthdB87.5TYP87.5TYP87.5TYPVideo to Noise Ratio≤60≤60≤60Video Frequency ResponsedB+ 0.75 MAX+ 0.75 MAX+ 0.75 MAXAudio ParameterInput LevelVp-p0.4 ( + 50KHz)0.4 ( + 50KHz)0.4 ( + 50KHz)Input ImpedanceKΩ0.8(Unbalanced)0.8(Unbalanced)0.8(Unbalanced)Pre-distortion%≤0.6≤0.6≤1Audio with FrequencyMHz4.5 5.5 6.5 (Optional)Pre-amphsiseuSEC50Audio to Noise RatiodB≥55Audio Frequency ResponsedB+ 0.5General PerformanceSupply VoltageVAC 180_250 (50Hz)ConsumptionW≤8DimensionMm483(L) X 210(W) X 44 (H)483(L) X 210(W) X 44 (H)483(L) X 250(W) X 44 (H)Product Process:
