Noise floor seems to be to high
Quote from asiaauser on 09/02/2022, 22:52Hello, we just recently purchased the Spectran V6 and are still learning to use it.
Using the wrapped spectrum, when we attempt to look at the noise floor we can't seem to get it much lower than -110 dBm. We are hoping to get closer to -174 dBm. Could this be a settings issue?

BTW: You are using a very old software. Please update to the latest version.

Quote from CYW on 19/08/2023, 05:08I set up a mission as shown in the attached figure, and send a microwave signal with 2.5 GHz, -85 dBm to the spectrum analyzer. The noise floor is around -152 dBm as shown in the attached figure. How can I achieve the -170 dBm noise floor?
