The GSA 1000 will convert any conventional oscilloscope into a highly cost effective spectrum analyzer. Bandwidth is
unimportant and the only requirement is for an X-Y mode.
High performance:
Despite its low cost the adapter offers excellent performance. The frequency range is 400kHz to 1GHz and the bandwidth (selectivity) is 250kHz. The center
frequency can be adjusted over the full frequency range with direct frequency readout on a large liquid crystal display. Both scan width and scan rate are fully
adjustable. The amplitude range is -70 to 0dBm and is highly accurate over the whole amplitude and frequency range. A front panel CAL button allows a calibrated
-30dBm 50MHz marker signal to be superimposed for precise amplitude and frequency checks.
Easy to connect and use:
The adapter connects to an oscilloscope via two BNC cables. The BNC input is true 50½ for low VSWR. A low capacitance Hi-Z connection can be made using a
standard 10:1 scope probe adjusted for 20dB attenuation.
A wide range of applications:
The GSA 1000 is suitable for many applications within research, development, servicing and education. Application areas include:
EMC Investigations:
Make estimations of spurious emission from equipment, locate sources and quantify the effects of modifications. Examine external interferences sources.
Oscillators and Transmitters:
Check frequency and harmonics, output levels and antenna efficiencies etc.
Receivers and RF Amplifiers:
Check LO?s, mixers, stag gains, bandwidths and alignment.
Education:
Demonstrate frequency domain techniques. Illustrate the fourier components of waveforms. Show the effects of mixing and intermodulation.
Production and Servicing:
Make rapid comparisons between good and faulty equipment. Trace RF signals through complete signal paths.
A portable and robust instrument:
The GSA 1000 adapter is compact and fully portable, housed in a robust ABS case with internal shielding.
