The RTSA7500 Series from Berkeley Nucleonics is a range of modular real-time spectrum analyzers that are designed to analyze wireless signals in the lab, on the manufacturing floor or out in the field. They have a real-time trigger mode for measuring complex data signals such as Wi-Fi and LTE along with markers for tracking specific frequencies. These analyzers can capture elusive and time-varying signals across real-time bandwidth (RTBW) up to 100 MHz and have probability of intercept (POI) as short as 1.02 μs. They have a spurious free dynamic range up to 100 dBc and DSP filtering and decimation.
