Signal Level Meter
XR-3W+
-
From satellite dish alignment, to UHF off-air antenna pointing, to cable TV MER measurements, the XR-3 is the meter for you! The XR-3 is the most capable meter offered by Applied Instruments. It's more durable than the popular Super Buddy meter, and has added features and performance. The XR-3's modular design with field swappable modules provides wide versatility to fit different measurement applications, including DBS satellite (i.e. Dish Network, DIRECTV, Bell TV, Shaw Direct), VSAT satellite (i.e. iDirect, Hughes Ku band, and more), VHF/UHF off-air (analog and ATSC digital), and CATV (QAM and analog). The XR-3 is great for installing and troubleshooting DISH SmartBox, Blonder Tongue, and other SMATV headend systems often used in hotels, multi-dwelling units, and institutional facilities.

Measurement Power Amplifier
Qam
-
The amplifier is DSP controlled, with a very straightforward operation. Included is a white/pink noise signal generator. The internal signal module provides low crest noise signals to be able to reach high power levels from sound sources or electromagnetic shaker. External input of signal is equally possible, with spectral linearisation or without. This can be used for music, RASTI or any other signal

RF R-PHY Video Engines
-
ATX’s RF R-PHY video engines provide a mux pass-through function that enables cable operators to maintain existing video encryption functionality on in-service edge QAMs, alleviating the need to migrate encryption functionality to the CCAP video core during early stages of DAA transition. ATX RF R-PHY video engines also relieve MSOs of undertaking back-office system integration to reconfigure and manage muxes and broadcast lineups in CCAP video cores. For MSOs considering an accelerated transition to IPTV, the ATX RF R-PHY Video Engine provides a low-cost and low-complexity alternative to implementing a CCAP video core.
