eg an IMD test on a 20kHz span would look very noisy.īut it only costs about £1000 new and this is quite remarkable. I suspect they chose this wide span to hide the fact the phase noise will spoil the appearance on narrow plots. It would be interesting to see how the IP3 holds up on narrow spans as the glossy brochure shows this test at a 10MHz span. Good enough for most testing but markedly inferior to a regular analyser. Another plot shows the phase noise to be about -105dBc/Hz at 100kHz offset. It does have a preamp to get the NF down to about 20dB but I would expect the input IP3 will suffer a lot with this switched in.

The input IP3 appears to be +12dBm with 0dB attenuation and this initially looks good but the NF is high so the 3rd order IMD dynamic range will be several dB worse than a half decent 'regular' analyser. In terms of signal sensitivity, the data suggests to me that the analyser noise figure with 0dB attenuation is about 40dB and this is about 15dB deafer than many bench analysers. It's so noisy I wonder if the analyser uses the same LO/mix strategy as the higher frequency versions. If you are not worried about close to carrier noise performance then I guess this isn't too much of a limitation but it is probably the noisiest analyser I have ever experienced in this respect. In one of their videos it shows -87dBc/Hz at 10kHz offset at the lower end of the analyser range. I downloaded the Rigol specs in one of their glossy brochures and it does look like the phase noise is going to be quite poor. The first obvious questions were who/what was Rigol and how could this be a real low cost contender? The US office is out of suburban Cleveland This Amateur Radio operator apparently feels the same about this I also found a thread in another forum for this here That is a fraction of the cost of other TG's of more expensive SA's.

The other part that 'floored' me was the cost of a tracking generator (which I consider essential) was only $200 more. Unlike Aten (in a similar price range) this looks like it might have some real quality. < -150 dBm + 6 x (f / 1 GHz) dB, < -155 dBm (typ.I stumbled across this SA and was floored by the price.

A shorter overview is available in the datasheet. The complete list of technical specifications can be found in chapter 6 “Specifications” of the manual.

#RIGOL DSA815 TG SPECTRUM ANALYZER MANUAL#

These functions enable the analyzer to acquire signals and match parameters automatically, compared to the manual process necessary with a traditional analyzer. The very large display (20.3 cm / 8″) of the Rigol DSA815-TG Spectrum Analyzer provides a resolution of 800×480 pixels allowing a very good overview of all its comfortable functions like Auto Tune, Auto Range, Auto Scale and Auto Couple. The use of digital IF (intermediate frequency) technology guarantees reliability and performance to meet the most demanding RF applications.
