The RSA603A from Tektronix is a RSA600A series laboratory USB spectrum analyzer with tracking generator. The RSA600 requires a PC with Windows 7, Windows 8/8.1 or Windows 10, 64bit operating system. A USB 3.0 connection is required for operation of the RSA600. 8GB RAM and 20GB free drive space is required for installation of SignalVu-PC. For full performance of the real time features of the RSA600, an Intel Core i7 4th generation processor is required. Processors of lower performance can be used with reduced real-time performance. It has real time display of spectrum with 100% probability of intercept of 100µsec signals in up to 40MHz span. It does basic vector analysis functions such as amplitude, frequency, phase vs. time, RF I and Q vs. time. It analyzes and re-analyze signal in 2-D or 3-D waterfall display. The signalVu-PC software offers real time signal processing with DPX spectrum/spectrogram to minimize time spent finding transient problems.
