Model D4841 L / C / Ku-band Downconverter Conversion Station
The Dominion Test Instruments Model D4841 is an affordable switchable Block Downconverter for both C-band and full global Ku-bands, as well as a pass-thru path for L-band. The unit contains integral RF routing. Simply enter the desired Frequency via the Remote Control GUI, and the appropriate conversion is selected and routed to the L-band output jack on the rear panel.
An option is available to integrate with a DTi Remote Carrier L band Monitor. In this mode, the Remote carrier monitor serial control cable is connected to the Conversion Station, thus allowing the customer to simply enter the desired L-, C-, or Ku-band frequency, and the Remote Carrier Monitor will automatically tune and display the selected input frequency.
All RF controls are accomplished via Remote Control using Ethernet or RS-232 (optional*). Control GUI included.
When used with the a DTi Remote Carrier L Band monitor, all communications for both the Conversion Station and the Remote Carrier Monitor are controlled via the Remote Carrier Monitor control GUI. Thus only one connection is required. If using the switch alone, a standalone GUI is supplied to control the conversion station.
