Signal Generator/Spectrum Analyzer (140MHz-4.0GHz) (VPL-SG-44)

Description
140MHz-4.0GHz simple signal generator, simple spectrum analyzer can be used for wideband signal generator, wideband sweep generator, simple spectrum analyzer. With noise source for tracking, generator can test parameters of filters, antennas, etc., and the equipment is so simple to carry. These devices were createdfor amateur radio enthusiasts to tune their antennas. It functions as signal generator as well as spectrum analyzer. This can be used to see the whole frequency range from 140 MHz to 4.0 GHz which is ideal to check on CATV, SAT, LTE etc.

“IN” is spectrum analyzer input, “OUT” is signal generator output, “PWR” is power inductor .When it power up, the PWR LED will begin to flashing and then constantly on . If PLL unlock the LED will be flashing all time (except for  output 0Hz).
