Issue Details

I'm testing my DUT using RFIC Test Soft Front Panel, and I observe a fact that no matter how I try to configure the parameters on the soft front panel, the output power (Y-axis) is always limited within 20 dB. Below are the testing results of AM-AM and AM-Gain, and you could clearly find such limitation.

However, when I checked "Powr vs. Time" diagram, it seems that the signal itself is not bounded within 10 dB as shown below:

Why is this happening? how do I do to solve this problem?

Solution

It's because the threshold level is set to -20 dB or dBm by default.
In RFIC Soft Front Panel, navigate to <Measurements> - <AMPM> - <Threshold>, set the "Level (db or dBm)" to a smaller number to increase the scale on the Y-axis output power.
