ICE 3000 Series
ICE3005
-
The ICE3005 is an agile filter/amplifier cascade for the UHF frequency band with a VHF bypass. It enables simultaneous operation of multiple transceivers in a cosite environment and is factory configured for an ARC-210 interface. This filter/amplifier provides multiple poles of RF selectivity to reduce broadband noise, harmonics, and spurious signals while still providing full output power in transmit mode and excellent selectivity to interfering signals at the transceiver’s RF input in receive mode. All transmit, receive, and bypass switching is incorporated into the two-port design. The ICE3005 also includes a separate audio processor circuit that mitigates popping and drop-outs in the R/T audio that are common in hopping or blanked waveforms. The ICE3005 incorporates extensive Built-in-Test capability and is qualified for military applications. A mounting tray is available for easy incorporation on your platform. Cost-effective modifications are available on the ICE3005. Please contact your sales representative at 513.870.9060 or Support@PoleZero.com for details.

Media Meter Software Tool
-
Dolby Media Meter is an innovative software tool that accurately measures loudness the way your viewers experience it in programming for broadcast, packaged media, cinema trailers, video on demand (VOD), and games. Differences in audio levels between programs and channels, or between programs and commercials, are a major annoyance to TV viewers. Although easy to hear, these differences are much more difficult to measure. And without accurate measurement, you can't regulate these irritating shifts in sound level.
