VISION A/V to COFDM Modulator (2 Input)
- Converts two A/V inputs onto a single COFDM DVB-T TV channel
- Simple front panel set-up with OLED function display. No computer required.
- VHF or UHF channel output for SD programmes
- PSI generation: SDT, NIT, LCN
- Adjustable RF output level
- Modular format for wall/bulkhead or DIN rail mounting
The V40-2000 COFDM takes 2 A/V signal sources and modulates them into a single UHF DVB-T channel in standard definition compatible with Freeview set-top boxes and IDTV’s.
The modulator has been designed to be simple to set up by the front panel removing the need to use a computer or handset. A single DTT channel can be created in the VHF or UHF bands for use with larger, more complex commercial SMATV systems. Compatible with the format of the V90-440 Quad single channel filter amplifier.
Input standard PAL (B, D, G, I, M, N) : SECAM , NTSC (M and 4.43)
Video input 20Hz to 6MHz
Level / Impedance 1V ± 0.1V / 75O
Audio input 20Hz - 15kHz
Level / impedance 775mV/10kO
Level adjustment +6 to -6 / 2dB steps
RF Output Level / Impedance / Frequency range 90dBµV / 75µO / 110 -862MHz
Level adjustment 0 to -10dB /1dB steps
Frequency range of RF loop-thru 47 - 2150MHz
Combining loss in RF loop-thru 1.5dB
Return loss =10dB
Fine tuning of RF carrier frequency offset ±125kHz / 250kHz in 0.25MHz steps
IF Bandwidth 7 / 8MHz
