Measuring Low frequenciesWhen measuring signals below 1MHz some annoying artifacts can appear. When we move the input signal to 0.3MHz at -15dBm we get a very different measurement The artifacts are caused by the AGC that is misbehaving below 0.5MHz. That is why in default mode the AGC is disabled when below 0.5MHz. The menu shown is the second page of the EXPERT CONFIG showing everything is on default/automatic. |
