All four resistors used are 1% parts. From my previous post, measuring the 1.0 and 0.1 mOhm resistors with the two old HP bench meters with unknown accuracy I would guess we are well within 5%. Noise floor of the SA vs the VNA.
Web22 nov. 2024 · You cannot just “tap” a transmission line, like you can a low-frequency circuit, off to the measurement instrument. If you add a second 50 Ω line in parallel with the existing line that's part of the device you're testing, you've made an impedance of 25 Ω — just like if you paralleled two 50 Ω resistors.

WebIn this method, the measurement of impedance takes place in two steps. Step 1 − Determining Vmin using load ZL. Step 2 − Determining Vmin by short circuiting the load. This is shown in the following figures. When we … WebCircuit for measuring impedance of a device by measuring two voltage drops. Theory Impedance is the total opposition to current flow in an alternating current circuit. It is made up of resistance (real) and reactance (imaginary) and is usually represented in complex notation as Z = R + jX, where R is the resistance and X is the reactance.
