Real-time spectrum analysers monitor intermittent and frequency-hopped wireless signals in real-time

Saelig now offers the Rigol Technologies RSA5000 Series of RF spectrum analysers. These real-time devices scan a complete frequency spectrum of 9kHz to 3.2GHz or 6.5GHz with a maximum sample rate of 51.2MS/s. They provide important performance improvements over traditional swept spectrum analysers with a 1ms full span sweep, an expanded vertical range to +30dBm, reduced phase noise to -108dBc/Hz, 1 Hz RBW (resolution bandwidth), and a reduced noise floor (DANL) to -165dBm. They can also be applied in a traditional swept scan mode. The flexible User Interface allows clients a choice for interacting with the units as they feature a 10.1" capacitive touchscreen display with gesture support, mouse/keyboard support, and also traditional knob and button control. Real-time spectrum analysers are crucial for users dealing with signals that vary dynamically in amplitude or are agile in frequency: frequency-hopping spread spectrum radios, pulsed radar systems, and pulse modulated radios; multi-signal environments.
