Gallery of pictures of LCF Meter in action
Final version of LCF-meter in aluminium box.
A 300MHz self test (without divider 1:10). Frequency is sourced from internal independent PLL.
Testing with sub-GHz generator (with divider 1:10), Clapp oscillator used as a source of signal.
Harmonic distorsion self test on center frequency 1kHz with filter on DDS output. Small board on left is active signal level shifter.
Testing capacitance between measuring spears on frequency 10 kHz
Test measurement on LC circuit (L ~ 470 uH, C ~ 10 nF)
Measuring impedance of small 8 ohm speaker
Measuring phase deviation between Morion MV89A an FEI FE-5680A (both bought on e-bay)
