Measurement Of Other Elements; Capacitors And Inductors - RigExpert AA-600 User Manual

3. Changing the display range and performing additional scans, find a frequency
where R (resistance) reaches its maximum, and another frequency with
minimum. At these points, X (reactance) will cross the zero line.
Example 1: 28.75 MHz – min., 60.00 MHz – max.
Example 2: 25.00 MHz – max., 50.00 MHz – min.
4. Switch the Data at cursor screen by pressing
previously found frequencies.
Example 1: 25.9 Ohm – min., 95.3 Ohm – max.
Example 2: 120.6 Ohm – max, 49.7 Ohm – min.
5. Calculate the square root of the product of these two values.
Example 1: square root of (25.9 · 95.3) = 49.7 Ohm
Example 2: square root of (120.6 · 49.7) = 77.4 Ohm

5.3. Measurement of other elements

Although RigExpert antenna analyzers are designed for use with antennas and antenna-
feeder paths, they may be successfully used to measure parameters of other RF
elements.

5.3.1. Capacitors and inductors

Analyzers can measure capacitance from a few pF to about 0.1 µF as well as
inductance from a few nH to about 100 µH. Since measuring of capacitance and
inductance is not a main purpose of RigExpert analyzers, the user will have to gain
some experience in such measurements.
Be sure to place the capacitor or the inductor as close as possible to the RF connector
of the analyzer.
