Verifying the performance of the test fixture for VNWA Reflect mode (S11)

Verification will be performed using the two types of test fixtures below.

Verify the difference in test fixture data using a 1000pF chip ceramic capacitor.

Verify the difference in test fixture data using a 100pF chip ceramic capacitor.

Verify the difference in test fixture data using a 10pF chip ceramic capacitor.

Verify the difference in test fixture data using a 100pF radial lead ceramic capacitor.

Verify the difference in test fixture data using a 1μH choke coil.

Verify the difference in test fixture data using a 150μH choke coil.

Verify the difference in test fixture data using a 235 Ω resistor.

In capacitance measurements, the difference between test fixtures was confirmed depending on whether resonance occurred or not. No differences in the test fixtures were identified in the inductance measurements. In resistor impedance measurements, differences in test fixtures were confirmed at frequencies above 300 MHz.
