Repeatability of Split Cylinder Resonator Temperature Characteristics (40 GHz, LCP)

Measurement Results

• The same sample was measured five times at each temperature point.
• After completing a measurement at one temperature, the temperature was changed before the next measurement (i.e., not repeated continuously at the same temperature).

Key Point!

• Even with a system that changes temperature between measurements, very high repeatability was achieved!
• Measurements taken by raising the temperature, lowering it, and raising it again produced consistent results.

When measuring materials, how consistently you get the same result (repeatability) is a critically important point.
When repeatability is high, researchers can detect even small differences in materials and effectively apply that knowledge in the next prototype. Similarly, in manufacturing, stable monitoring of samples enables higher-precision quality control.

Here we show the results from repeated measurements of an LCP film. One set consisted of measurements while changing the temperature from 150 °C → 100 °C → 50 °C → 25 °C → 0 °C → -50 °C, and this was repeated for a total of five sets.
Note: The temperature was not held at 150 °C for five consecutive measurements; instead, it was changed frequently between measurements. Even under these conditions, the measurement system shows very high repeatability.
