Willtek's 9101 Handheld Spectrum Analyzer Provides New Level Of Flexibility And Portability For The Biomedical Industry
"The beauty of the 9101 product is that it's totally portable and replaces much larger, PC-based units. This is a huge benefit for those in the Biomedical industry that most often must transport large, cumbersome units on carts within a hospital or large physician practice," said Willtek Sales Engineer Mark Aronson. "The convenience, cost savings and state-of-the-art technology also comes with a very competitive price."
Within the biomedical industry, critical spectrum analyzer applications include:
*Testing and troubleshooting medical monitoring devices
*Identification of all interference sources, both internal and external
*Retrieval of lost probes, antennas and actual monitoring devices
The Willtek 9101 is a proven leader in the test and measurement industry. During the February, 2004 APEX and IPC printed circuits Expo in Anaheim, California, Willtek received the "Test Product of the Year" award from Test & Measurement World magazine for its 9101 Handheld Spectrum Analyzer.
Willtek designs its test equipment to enable increased efficiency and productivity for network operators, handset manufacturers, and service providers. However, the functionality and portability of the 9101 make it ideal for many applications outside of the traditional wireless industry.
Typical measurements look at transmitter characteristics, alignment of modulators and measure amplifier gain. With a frequency range of 100 kHz to 4 GHz, the 9101 can test all modern wireless local oscillators, plus the harmonics and spurs that sneak into the pass-band. The 140 degree viewing angle and color display with enhanced graphics provide a perfect view of all details. Manual operation is easy with many marker functions, storage of setups and user-defined limit templates. With the built-in remote control capability via RS-232 or LAN, the 9101 is also used in monitoring and automated test environments.
Recent software versions have added new functions and improvements to the Willtek 9101. The latest versions have added pre-defined, application-oriented capabilities which allow technicians to focus on measurement and alignment. This will ease their job and help them become more effective in their work. These new functions are possible in a spectrum analyzer only because the 9101 has a power measurement accuracy that is unmatched in this price range.

In addition to the channel power measurement capability that is already available, the new application includes adjacent channel power ratio and occupied bandwidth. Both functions allow a selective measurement in modulated broadcast and carrier systems e.g. GSM, UMTS, WLAN and cable TV.
Two new functions help to achieve proper absolute power measurement results when the external RF connection differs from a standard setup. Attenuation or gain introduced by external cabling and devices can now be compensated by the software. 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 uses 75 ohms while most other RF equipment applies 50 ohms impedance.
