And by the way, the XG1 and XG2 also have more or less square-wave output. This is where the harmonics come from that allow them to put out a useful signal on higher bands.
For the intended applications, this waveform is not an issue, because the receiver under test will virtually always have a low-pass filter at its antenna input. 73, Wayne N6KR On Apr 15, 2011, at 3:19 PM, Wayne Burdick wrote: > The XG3's phase noise is a constant -105 dBc/Hz.
