The Decimator D3, the third generation of SED Systems’ family of spectrum analyzers, now includes such functions as carrier monitoring and cross-pol isolation testing.
The D3 works in the 5 MHz-3 GHz range, making it suitable for the testing of cable, wireless and satellite networks. It performs 10 measurements per second, and it can be used be several technicians at the same time. According to the company, users can display, compare, store, report and export multiple traces. Preset configurations can be saved and recalled later.
Decimator D3 can be accessed from any network-connected location – either locally or remotely. An API is available for integrated/OEM applications.
For cable networks, the D3 can monitor upstream or downstream carriers, and monitor RF in the headend, hub or elsewhere in the cable network. For terrestrial wireless networks, it can monitor forward or return path carriers, and perform remote RF monitoring at a cell tower to reduce truck rolls. For satellite networks, the analyzer can monitor uplink or downlink carriers at L-band or 70MHz/140 MHz or 10 MHz reference signals.
Decimator D3 is available in three form factors:
>> Decimator D3 card – a small (4-in. x 7-in.) PCIe card installed in a computer or integrated into small enclosures or chassis. Powered from +12/+5 Vdc.
>> 4/8-Port Decimator D3 – a 1U rack-mount unit with an integrated 8-port RF switch. Provides low-cost spectrum measurement and analysis. Can be installed in an equipment rack and connected to multiple feeds. Also available in a 4-port configuration.
>> Portable Decimator D3 – a handheld enclosure for field technicians who need a highly portable unit that can be used with any laptop computer.
Custom designed versions of the Decimator, supporting other frequency bands or form factors, also are available.
