When you're shopping for an oscilloscope or signal analyzer, the first fork in the road is whether you want one instrument that covers several jobs or a dedicated RF tool with a much wider frequency reach. This head-to-head puts a $225 open-box multi-function scope against a $4,111 as-is RF analyzer, so the decision is about condition and capability as much as price.
Quick Verdict
Choose the FNIRSI DPOS350P if you need a working instrument today and want the convenience of a single bench unit. Choose the Agilent N9010A EXA only if you are prepared to repair it or use it for parts. The Agilent's RF reach is the main draw, but this is not a ready-to-measure analyzer.
At a Glance
| Product | Price | Condition | What You Are Looking At |
|---|---|---|---|
| FNIRSI DPOS350P 4-in-1 Digital Oscilloscope | USD 225.00 [#---------] | New - Open box | 350 MHz bandwidth, 2 digital channels, 7-inch 1024x600 display, 1 GSa/s sampling, 50,000 wfm/s capture, signal generator plus spectrum analyzer |
| Agilent N9010A EXA RF Signal Analyzer | USD 4,111.00 [##########] | For parts or not working | 9 kHz to 7 GHz frequency range, benchtop analyzer, installed options /507 /B25 /PFR and N9060A/N9073A feature licenses |
Where Each Product Wins
- FNIRSI DPOS350P wins when you want a functioning all-in-one bench tool. It keeps several measurement roles in one chassis, and you are not taking on a repair project.
- Agilent N9010A EXA wins on RF reach and installed options. The wide frequency range puts it in a different class for spectrum analysis, but that advantage only matters if you can bring the unit back to working order.
Product Notes
FNIRSI DPOS350P 4-in-1 Digital Oscilloscope
The FNIRSI DPOS350P is the unit to reach for when you want one instrument that can do several jobs on a bench. It combines a 350 MHz bandwidth oscilloscope, a signal generator, and a spectrum analyzer in a 4-in-1 design, and the 7-inch 1024x600 display makes the menus readable. With a real-time sampling rate of 1 GSa/s, a maximum capture rate of 50,000 wfm/s, and a 1 ns rise time, it is built for general high-speed signal work rather than deep RF analysis. This configuration gives you two digital channels and DC/AC input coupling, which covers a lot of everyday troubleshooting. The limitation is that it is not a multi-gigahertz RF instrument; its 350 MHz bandwidth sets the practical ceiling, and the 2-channel front end means you cannot monitor three or more signals at once.
Agilent N9010A EXA RF Signal Analyzer
The Agilent N9010A EXA is a benchtop RF signal analyzer with a 9 kHz to 7 GHz frequency range and a set of installed options, including /507, /B25, /PFR, and N9060A/N9073A feature licenses. That frequency reach is the reason it belongs in this comparison: it goes far beyond what a general-purpose oscilloscope can see. But the condition is unambiguous: the unit is for parts or not working, does not display a signal trace, reports a Misc/System Alignment Failure and a system error, has an internal measurement error, and has a ripped front panel 3 key. It is also untested and sold as-is. So the right way to think about it is as a repair project or parts source, not as a functional analyzer. If you can resurrect it, the installed options and wide range could make it a strong bench instrument; if not, the value is in the components.
Final Choice by Use Case
- Need to make measurements today: FNIRSI DPOS350P. It is the working unit in this pair, and the multi-tool design gives you several analysis options in one box.
- Need an RF analyzer and can handle repairs: Agilent N9010A EXA. Treat the purchase as buying a repair project or parts unit. The installed options add to its appeal, but the reported errors mean you should plan around bringing it back to life.
