RSA503
The Tektronix RSA503A is a ruggedized portable spectrum analyzer meant for field or lab use with a frequency range of 9 kHz to 3.0 GHz. The user interface and display resides on a user-provided PC running SignalVu-PC software or a user-developed application. The host PC provides all power, control, and data signals over the USB 3.0 cable included with the instrument.
Signal processing while running SignalVu-PC software provides real-time processing of for general signal analysis, analog modulation analysis, and RF measurements.
An optional tracking generator enables gain/loss measurements for quick tests of filters, duplexers and other network elements.
