Quick take
Choosing a signal spectrum analyzer for RF work usually comes down to a trade-off between measurement range and condition. The four listings here span from a PC-based analyzer at the lower end of the price spread to a benchtop instrument at the higher end, with a powered-on Agilent N9320B in between. Two of the listings are matching Agilent N9010A EXA units with the same stated condition, so the real question is whether you need a unit you can measure with soon or a project you are willing to repair. The listed-price comparison below makes the spread visible.
Listed-price comparison
| Listing | Listed price | Price bar | What you're buying |
|---|---|---|---|
| Agilent N9320B | USD 1,200.00 | Used spectrum analyzer, 9 kHz to 3 GHz, powers on, out of calibration, sold as-is | |
| Aaronia AG HF 6080 | USD 400.00 | Used PC-based signal analyzer | |
| Agilent N9010A EXA (higher-priced listing) | USD 4,850.00 | For parts or not working, 9 KHz to 7 GHz, installed options listed, sold as-is | |
| Agilent N9010A EXA (lower-priced listing) | USD 4,111.00 | For parts or not working, 9 KHz to 7 GHz, installed options listed, sold as-is |
Decision matrix
- If your priority is a unit described as powering on and functioning, and you can accept an out-of-calibration instrument, the Agilent N9320B is the match.
- If the lowest listed price and a PC-based analyzer workflow are what you are after, the Aaronia AG HF 6080 is the match.
- If you are shopping for the N9010A EXA platform as an as-is repair or parts project, the lower-priced of the two matching N9010A listings is the more direct choice because the two share the same stated condition.
Product notes
Agilent N9320B RF Spectrum Analyzer
The Agilent N9320B is the only listing in this group described as a unit that powers on and functions. That makes it a practical pick if you want to start measuring soon after the analyzer arrives. Its listed frequency range and displayed average noise level give you useful comparison points, but the calibration status is the catch: the unit is out of calibration, sold as-is, and does not include accessories or a power cable. If your lab can manage calibration or you simply need a functional RF analyzer for basic troubleshooting, this is the more usable option. If you need calibration-ready measurements, you will need to factor in that service.
Aaronia AG HF 6080 RF Spectrum Analyzer
The Aaronia HF 6080 is the least expensive listing here, and it is described as a PC-based signal analyzer rather than a standalone benchtop instrument. That makes it a reasonable fit for someone who already works with PC-connected test gear or wants a low-cost way to explore RF spectrum analysis. The used condition means you should expect whatever wear comes with a secondhand test instrument. If you do not already use PC-connected test gear, the workflow will be different from a bench analyzer. For the price, it gets you into the product category without the larger cash outlay of the Agilent benchtop listings.
Agilent N9010A EXA RF Signal Analyzer (higher-priced listing)
This N9010A EXA listing is one of two with the same model name and the same stated condition. What it offers is the Agilent EXA platform with the installed options called out in the listing. The reason to consider it is the platform itself: if you need an EXA-series analyzer and are willing to buy a non-working unit, this is a way into that configuration. The limitation is serious: it is listed for parts or not working, untested, and sold as-is, with errors noted and a damaged front-panel key. Because the other N9010A EXA listing matches this description, the higher price is hard to justify unless something about this specific listing matters to you.
Agilent N9010A EXA RF Signal Analyzer (lower-priced listing)
This is the matching N9010A EXA listing with the lower listed price. It carries the same model name and the same stated condition as its higher-priced counterpart. If you have already decided you want the EXA platform as a repair project, this is the more sensible entry point. The trade-off is unchanged: the unit is for parts or not working, untested, and sold as-is, and the listing notes system errors and a damaged key. You are buying a project, not a ready-to-measure analyzer, so the condition should be baked into your decision before the price is.
Final recommendation by use case
If you want a functional RF spectrum analyzer and can handle calibration, choose the Agilent N9320B. If your priority is the smallest listed cash outlay and a PC-based workflow, choose the Aaronia AG HF 6080. If you need the 9 KHz to 7 GHz N9010A EXA platform and are ready for an as-is repair or parts project, choose the lower-priced N9010A EXA listing; the higher-priced listing only matters if you have a specific reason to pay more for the same stated configuration.
