When you're choosing between RF signal spectrum analyzers for your bench, the first fork is usually practical: do you want a self-contained tool or a dedicated test platform? The TinySA Ultra+ ZS407 and the Agilent N9010A EXA frame that dilemma clearly, because one is a compact analyzer and the other is a surplus analyzer.
Quick Verdict
The TinySA Ultra+ ZS407 is the more direct fit if your priority is portability. The TinySA is the choice when you expect to pick up the instrument and move it around the shop. The Agilent is the choice when you are building a test setup around one specific analyzer. The Agilent N9010A EXA is aimed at someone who specifically wants the Agilent analyzer platform. For most hands-on bench work, the TinySA is the easier recommendation; for a deliberate repair project, the Agilent earns a closer look.

Where The TinySA Ultra+ ZS407 Wins
- It is labeled as New, so it avoids the condition uncertainty that surrounds the Agilent.
- Its 4-inch display, 5000mAh battery, and 32GB storage make it a self-contained option.
- The title pairs the spectrum analyzer with an RF signal generator, giving it a second use on the bench.
Where The Agilent N9010A EXA Wins
- Its 9 KHz to 7 GHz range is clearly stated.
- It includes installed options such as /507, /B25, /PFR, plus N9060A and N9073A feature packages.
- Its benchtop form factor and Agilent part number make it a recognizable platform for buyers who need that specific analyzer.
Product Notes
TinySA Ultra+ ZS407
If a compact, self-contained signal spectrum analyzer fits your workflow, the TinySA Ultra+ ZS407 is the easier of the two to justify. It is labeled New, includes a 4-inch display, a 5000mAh rechargeable battery, and 32GB of storage, and the title mentions an RF signal generator alongside the analyzer. For USD 199.00, that combination is its strongest reason to choose it. The limitation is the model identity: the title says TinySA Ultra+ ZS407, while another model name appears as NanoVNA-H4, so you cannot be entirely sure from the name alone which device you are getting. Similarly, the frequency range appears as 10kHz-1.5GHz in one place and 100kHz-7.3GHz in another, which leaves the actual coverage unresolved.
Agilent N9010A EXA
The Agilent N9010A EXA is for the buyer who already knows they want this benchtop platform. It comes with a 9 KHz to 7 GHz range, and the installed options include /507, /B25, /PFR, plus N9060A and N9073A feature packages. Those details are the reason to consider it. The limitation is the condition: the unit is described as for parts or not working, with a misc/system alignment failure error, an internal measurement error, a ripped front-panel key, and an error log with multiple entries. It is also described as untested. At USD 4,850.00, that is a substantial investment for a repair candidate rather than a ready-to-run instrument.
Final Choice By Use Case
Choose the TinySA Ultra+ ZS407 if you want a battery-powered compact analyzer. Choose the Agilent N9010A EXA only if you are specifically after the Agilent platform.
