The accuracy depends on the impedance being measured, the quality of calibration and degree of averaging. Typical accuracy for 6 standard loads at 36 points over the available frequency range is tabled below in polar impedance format, after factory calibration, with Averaging = 64 and 100% power output.
|System Impedance Zo
