ESU-2050: A Replacement for the Discontinued Fluke 8920A Instrument
The Fluke Electronics Model 8920A Digital Wide-Band True RMS Voltmeter with BNC
Input was widely adopted by electrosurgical generator manufacturers around the world.
Fluke Electronics discontinued this instrument and ceased all shipments by the end of
1999, leaving a void in the industry. Since the formal discontinuance of the 8920A,
several electrosurgical generator manufacturers have searched for a suitable
replacement instrument capable of delivering the same functionality and at the same level of accuracy as the
8920A. But none had been found up to and including the beginning of 2007. The development of the new BC
Biomedical ESU-2050 ESU analyzer was by design, intended to provide a suitable replacement for the Fluke
Electronics 8920A instruments currently in use by these manufacturers.
ESU-2050: Unprecedented 1% Accuracy In ESU Testing
The accuracy specifications (see ESU-2050 specifications on Page 21) of the new BC Biomedical ESU-2050 ESU
analyzer are well beyond any competitive ESU analyzer of the market today, meeting the requirements of even
the most demanding electrosurgical manufacturers. The ESU-2050 ESU analyzer allows the customer to test
according to the exact same methodology as the electrosurgery generator manufacturers test their own products.
This is an industry first! Now these manufacturers will be using the exact same instrumentation for test and
measurement that typical electrosurgery generator customers do!
ESU-2300: A More Conventional Approach
For those customers that do not wish to make the quantum leap from
conventional ESU testing methodologies to the new ESU-2050
platform, the new BC Biomedical ESU-2300 analyzer offers a more
conventional approach to ESU testing. The ESU-2300 utilizes some of
the best attributes of the ESU-2050 design:
•
Patent pending DFA
®
Technology
•
Industry standard current sensing technology via a custom
design current transformer designed specifically for the BC
Biomedical ESU-2300 by Pearson Electronics
•
The latest in microprocessor design, which allows for high
speed digital acquisition and “interrogation” of the
electrosurgery generator waveform
The ESU-2300 is a mid-range analyzer (similar in price point to the Fluke Biomedical RF-303
RS
), but offers
superior features and accuracy (as result of the implementation of current sensing technology).
ESU-2400: More High-End Technology to Come
Is anything missing form the new BC Biomedical ESU-2000 Series lineup? What about a “high-end” analyzer?
The new BC Biomedical ESU-2400 “high-end” ESU analyzer is currently under active development. Stay tuned to
BC Group International, Inc. for more to come on the new BC Biomedical ESU-2400.
Common Element: Patent Pending DFA
®
Technology
The common element of all instruments in our new ESU-2000 Series is our patent pending DFA
®
Technology.
This technology platform allows the instrument to aggressively digitize the RF signal, analyze its components, and
provide highly accurate results. No other ESU analyzer on the market today uses this type of technology
platform. Not even the “high-end” competitive instruments offer this advanced level capability!
