0° to 360°, 10 ohms to 100 kohms 500kHz to 108MHz industrial
The HP 4815A RF Vector Impedance Meter provides all the convenience of "probe and read" measurements. In use, the probe is connected directly into the circuit to be evaluated, frequency is selected, and complex impedance is read. This type of measurement allows a straight forward adaptation to various jigs and fixtures for special measurements. Where only component values are to be determined, a quick mount adapter is provided to allow rapid measurements. For critical component applications, the unit to be evaluated may be mounted directly in its working circuit and its value determined in its actual environment, at the frequency of intent. Frequency range: 500kHz to 108MHz in 5 bands ±2% of reading. Impedance magnitude range: 10 ohms to 100 kohms in 9 ranges ±4% full scale. Phase angle range: 0 to 360° in 2 ranges. Phase angle calibration: increment of 2° Analogue outputs for magnitude and phase indications
