For a compact impedance analyzer, the measurement accuracy at frequencies up to 1300 MHz is comparable to "professional" instruments. I use it and analyzers love it to design, build and test a finished antenna (system). Also good for circuit analysis. Generator output on time after 20 min, stable up to 5*10-8Hz (15Hz at 2700MHz), frequency accuracy within specification. It can be used as a signal source for some types of tests. Excellent value for money and quality.
