With a signal generator (SG), you can make a measurement of various parameters of your device. One example is impedance measurement.
A fixed attenuator is inserted in front to improve the souce match. For 6dB attenuation, use R1=39 [ohm], R2=R3=150 [ohm]. “X” is the device under test (DUT), and R4=R5=R6=50 [ohm]. In the photograph, a 100 [ohm] resistor is employed as a DUT.
IC-7410 with tx frequency 7026kHz is used as a SG. RF power is minimized to 2 [W]. CH1 (in red) shows “V1”, and CH2 (in yellow) shows “V2”.
Since the DUT, a 100 [ohm] resistor, is pure resistive, there is no phase difference between the two waveforms.
By solving a simple equation, we conclude that the impedance of our DUT is 94.6 + j*0 [ohm].
