I recently noticed my Pluto seems to be putting out a little bit less power than it used to. I'm pretty sure I used to see more or less about 7 dBm output across 400 MHz to 2 GHz. However, I now see only about 1.5 to 2 dBm between 1.5 to 1.7 GHz. Below is a simplistic "sweep" between 400 MHz and 2 GHz in 100 MHz increments. Has anyone else seen this? Could I have damaged the power amplifier somehow?
Note: Measurement setup includes a 3 foot SMA cable, DC Block, and SMA to N connector. I have updated the firmware to v0.23, but everything looks the same.
