Product ManualManual

The ZMOD-X1 modulator series is an all inclusive unit that is loaded with features most needed by broadcasters. In it's most basic form, the unit comes with DVBS (QPSK), DVBS2 (QPSK and 8 PSK) modulation schemes, IF output, L-band output and ASI & IP input all as standard features. 16 and 32 APSK modulation are provided as options. Taking mobile and portable systems in mind, the unit comes with clear and user friendly front panel control. Size and weight are significantly less than any unit on the market. The unit can also be monitored and controlled using any web browser.

  • DVBS-QPSK/DVBS2 (QPSK, 8 PSK) standard.
  • Clear and user-friendly front panel control.
  • Front panel monitor port.
  • Only 10" deep and weighs 4.5lbs.
  • Rear panel Ethernet port for user interface.
