Modulator for PCI-Express
DMB-8038  Modulator for PCI-Express
DTVANE modulation card is a real-time encoding signal generator to support all of digital TV standard in the world. Specification of RF output is as good as professional equipment and Card supports all constellations and modulation modes for each supported standard, and it supports VHF, UHF and L-band All-Band output, which has high precision and high level output, it can meet a wider test radius for wireless testing with no extra amplifier. Also, it has excellent performance of signal quality, and test stream support. It could meet any customer request through its high stability, compatibility, cost-effective and user friendly GUI!
 
Modulator for generating any cable, terrestrial and satellite modulation standard currently in the world, including multi-PLP DVB-T2 and DVB-S2X. Advanced features include ultra-low phase noise, phase noise emulation and special license for different standard modulation. The output frequency of the DMB-8038 series is agile in the range from 40MHz~2150MHz.
 
Dependent on the license, the DMB-8038 series operates as a single up to 72-MHz modulator in VHF, UHF or L-band.
 
When operating as a single modulator, the DMB-8038 SERIES allows you to modulate one channel with a maximum bandwidth of 72MHz anywhere in the VHF/UHF band for terrestrial and cable standards, and anywhere in the L-Band for satellite standards.
