CSA2026 Signal Analyzer

CSA2026 signal analyzer reaches the frequency from 100 kHz to 26.5 GHz with up to 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.

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