Dual Input Portable Spectrum Analyzer
The PSA-45DSI has frequency coverage of 950 - 1450 MHz, though signals just outside the band are also visible. Viewing the entire band enables the user to quickly determine polarization, and adjust for peak signal level. The screen has a fast refresh rate, so that response to dish movement or signal variation is almost instantaneous.
The PSA-45DSI has been designed with the satellite technician in mind. LNB power selector (12 V/off/18 V) and 22 kHz signal selector (on/off) are provided. On-screen menu function keys control selection of either or both inputs, display contrast, a peak hold function, toggle grid lines on and off and control a horizontal marker. Other controls include adjustable span plus center frequency tuning, providing additional resolution and information.
