可测灵敏度的便携式数字电视调制器
The digital streaming DTV/Mobile TV modulator with USB connection have ability to stream an MPEG<br />
stream from hard disk and output an industry-standard 50-870MHz (VHF + UHF) RF signal. The on-board<br />
synthesizer can generate a stable and accurate symbol clock and tuning frequency. The Transport Stream<br />
can be supplied via an external USB2.0 interface, and full customer-selectable modulation adjusted to<br />
exactly what customers need. And can be upgradable other modulation without hardware Factory return,<br />
but in the way of simple on-line proceeds, if purchase license update<br />
Moreover, VHF and UHF mode RF AMP and step attenuator have ability to amplify professional quality RF<br />
level +10 dBm to -110 dBm range. The professional range of RF power controlling should be very much<br />
ideal for adjacent selective, Min/Max level of RF Sensitive Testing.The USB modulator is fully hard-ware base of FPGA design solution, that can be enough to use with even low performance laptop on low CPU share Usage,and easy carry for field test, and your product demonstration.<br />
