I recently purchased the DSG815 to replace my ageing (and bench-room gobbling) HP8648b. At £1709 plus tax, I wasn't expecting a brilliant performer, just something that was good enough to get by. Boy, was I surprised! It's every bit as good as the old HP, the only slight downside being the output attenuator which cannot reduce the signal beyond -110dBm. However, that's easily taken care of with an outboard 20dB pad. Close-in phase noise is about 20dB better than the HP and the unit is extremely 'RF tight', with no sign of RF radiating from the case. Harmonic output beats the published spec by around 20 dB and is generally about 5dB better than the HP across much of the spectrum. Frequency stability is very good despite the standard ref osc being a rather so-so unit, as I wasn't prepared to pay over £500 for the 'parts in a billion' Rigol option. The fan is quiet, which comes as a blessed relief after the blow-hard HP. A quick nod to Telonic of Berkshire for getting this instrument to my door overnight.
