    Product Overview WCA330 and WCA380 are wireless communication analyzers equipped with a 3 GHz/8 GHz down-converter to analyze Radio Frequency (RF) signals. The newly adopted architecture allows concurrent acquisition of time and frequency domain data and display of measurement results in color. The analyzer provides a wide variety of functions such as spectrum, power, analog and digital modulation, and CDMA analyses.
  • Page 33 Features The analyzer has the following features: H Measurement frequency range: DC to 3 GHz for the WCA330 DC to 8 GHz for the WCA380 H Measurement span: 100 Hz to 3 GHz H Concurrent processing of real-time frequency and modulation analysis...
