CSA Series Signal Analyzer

Overview Specifications Ordering Resources

Saluki CSA series signal analyzer reaches the frequency from 100 kHz to 26.5 GHz with a maximum of 40 MHz analysis bandwidth. It can test signal power, frequency, phase, P-1, TOI, OBW, channel power, spurious, ACPR, CCDF, SEM, EVM, and other indicators. It can be used independently or combined with the chassis to form a test system.

CSA series signal analyzer is a cost-effective tool for essential signal characterization. Its capabilities provide a solid foundation for testing in general-purpose and educational applications.
