Tektronix RSA603A 3 GHz Usb Real Time Spectrum Analyzer 40 MHz Resolution Bandwidth

The portable RSA603A brings Tektronix DPX® real-time analysis to 9 kHz–3 GHz in a 5.6 kg USB form factor. Its 40 MHz capture path and 100 µs probability-of-intercept expose frequency-hopping, EMI bursts and wide-channel WLAN or 5G FR1 signals in a single sweep, while a –160 dBm/Hz noise floor and ±0.2 dB amplitude accuracy protect tight EVM and spur margins. SignalVu-PC software, GPS receiver and optional 6 GHz tracking generator turn the analyzer into an all-in-one tool for design validation, production alignment and field troubleshooting—delivering Tektronix precision and SCPI/LAN/GPIB automation at a fraction of new-instrument cost.
