VIAVI JD785A CellAdvisor Base Station Analyzer

The Viavi JD785A CellAdvisor Base Station Analyzer, is the optimal tool for installation and maintenance of cell sites, supporting RFoCPRI and narrowband IoT testing, spectrum and interference analysis, and more. A CellAdvisor JDSU JD785A Base Station Analyzer is the optimal test tool for installing and maintaining cell sites. It contains all the features and capabilities required for testing cell sites for all 2G to 4G wireless technologies. Equipped with one-button standards-based measurements for wireless signals, the analyzer offers a full scope of BTS conformance tests. Its combined functionality includes spectrum analysis, cable and antenna analysis, an RF/optical power meter, interference analysis, a channel scanner, E1/T1 analysis, and signal analysis.

Standard Calibration $450.00 *
*This is a Web introductory price for one calibration of the VIAVI JD785A. Price does not in most cases include measurement performance data. Pricing does include NIST traceable calibration and issue of a calibration certificate and calibration label. Pricing may vary slightly due to volume and location of laboratory supporting calibration. Volume pricing may apply. On-site fees may apply depending on logistics, location and volume of work to be completed during the visit.

Data Rate
Data Rate is the maximum number of bits of information which can be transmitted per second, as in a data transmission link. Typically expressed as megabits per second (Mbps).

Optical Signal-to-noise Ratio (OSNR)
Optical Signal-to-noise ratio is the ratio between the signal power and the noise power in a given bandwidth. Most commonly a reference bandwidth of 0.1 nm is used. This bandwidth is independent from the modulation format, the frequency and the receiver. For instance a OSNR of 20dB/0.1nm could be given, even the signal of 40 GBit DPSK would not fit in this bandwidth. OSNR is measured with a Optical Spectrum Analyzer. It is generally measured at the wavelength of interest.

Synchronous Optical NETwork (SONET) is a fiber-optic transmission system for high-speed digital traffic. Employed by telephone companies and common carriers, speeds range from 51 Mbps to 40 Gbps. SONET is an intelligent system that provides advanced network management and a standard optical interface. Specified in the Broadband ISDN (B-ISDN) standard, SONET backbones are widely used to aggregate T1 and T3 lines. The European counterpart to SONET is the Synchronous Digital Hierarchy, and the term "SONET/SDH" is widely used when referring to SONET
