LordFancypants1My guess is that a hobbyist would use this as a tracking generator in conjunction with their spectrum analyzer to characterize RF components like filters and amplifiers. The idea is that you take signal generator and output a sine wave, then sweep it's frequency over a range while tracking the frequency response of a device under test with your spectrum analyzer. Imagine doing this to a filter to verify that it's passing the correct frequency range, or verifying the linearity of your amplifier design.
I would agree with TheOtherJohn that this this lacks proper specification information, and that it probably performs adequately for it's $130 price-point.
