Issue Details

I’m currently encountering an issue during measurements using my RFSA or RFSG. Specifically, I’ve observed that the amplitude readings are fluctuating and not remaining stable, which is affecting the consistency of the results.

Solution

This issue may have been caused by recent changes to the connection setup. To resolve it, we recommend carefully dismantling the existing connections and reconnecting them using the appropriate torque wrench to ensure proper contact and stability.

Once the reconnection is complete, please perform a self-calibration on the module. This step is essential, as performing a self-calibration after any connection changes is crucial for maintaining measurement accuracy and optimal performance.
