inductance measurement

Thank you, Have a look first.

Re: measuring inductance

you can use a network analyzer. You can determine the Q value from group delay obtained from the network analyzer.

Hi can you explain how to measure the q factor of an inductance with the network analyzer?

Re: inductor measurement

One of the easiest ways of measuring L is to build an LC oscillator with known capacitance, measure frequency and calculate the inductance from the common LC-tank equation: ω=1/√LC --> L=1/ω²C, where ω=2Πf ..
See circuit below ..

I cannot make out the value for the C4 capacitor?

FYI-1.
Now one-box solution is available for impedance analysis and network analysis
Agilent | E5061B ENA Series Network Analzyer

Key features

Fully supports traditional ZA functions
- Plots impedance parameters (Cs, Cp, Ls, Lp, |Z|, … etc)
- Cal/compensation capabilities for test fixtures
- Equivalent circuit analysis

Covers various ZA applications with three measurement techniques using both S-parameter and Gain-phase test ports.
- Impedance analysis firmware option for the E5061B-3L5 5 Hz-to-3 GHz network analyzer (not applicable to the E5061B-115 to 237 RF NA options)


FYI-2.
When you like the traditional impedance analyzer, E4991A (1 MHz - 3 GHz) will be the best solution.
