RF instrumentation maker Willtek Communications announces new software for its Willtek 9101 Handheld Spectrum Analyzer. Read the recent eeProductCenter review of the 9101 here.

The newest software for the 9101 will increase its measurement capabilities, helping users to find faults, and to repair and align RF devices in cable TV, wireless LAN, mobile communications systems.

It's application-oriented

The software improvements in the 9101 tester bolster the functions it already provides by adding pre-defined, application-oriented capabilities.

In addition to the channel power measurement capability already available on the 9101 portable, the new software lets users measure adjacent channel power ratio (ACPR) and occupied bandwidth. Both functions support a selective measurement in modulated broadcast and carrier systems.

Two new functions also help to achieve proper absolute power measurement when an external RF connection differs from a standard setup. Attenuation or gain introduced by external cabling and devices, for example, can now be compensated for by the software.

75-ohms as well

In addition, cables and transmitters with an impedance of 75-ohms can be connected through an adaptor in combination with the new software to compensate frequency-dependent losses. This is important because TV equipment typically uses 75-ohm cabling and ports, while most RF equipment uses a 50-ohm impedance standard.
