ESA-E Spectrum Analyzer, 100 Hz to 6.7 GHz Customers looking for a general purpose spectrum analyzer will appreciate the flexibility of the ESA spectrum analyzer that can be used for a wide range of applications from aerospace and defense to the manufacturing line. Browse the ESA Brochure. Customers who wish to take advantage of the ESA flexibility but who need a faster analyzer for the manufacturing line, or connectivity to LAN/USB in addition to GPIB, or want to do in depth signal analysis with 89600B VSA software will benefit from the new EXA signal analyzer. The EXA signal analyzer now comes standard with many of the ESAs optional features and yet offers more applications than the ESA. Speed 0.
