Choosing between two Agilent/Keysight RF analyzers often comes down to a gamble between repair cost and ready-to-use performance. The N9010A EXA is a surplus unit priced at $4,111, but it is marked as for parts or not working. The E5052B Signal Source Analyzer is a used unit offered at $36,500. Your decision hinges on whether you can turn a damaged analyzer into a working instrument or need a signal/phase noise analyzer right away.
Quick verdict
If you need an analyzer for signal source and phase noise measurements and can spend near $36,500, the E5052B is the clear choice. If you have the skill to repair a unit with known system/alignment errors and want to enter the 9 kHz to 7 GHz spectrum analysis range at $4,111, the N9010A is the lower-priced risk.
Comparison

|---|---|---|
| Price | USD 4,111.00 | USD 36,500.00 |
| Condition | For parts or not working | Used |
| Frequency range | 9 kHz to 7 GHz | 10 MHz to 7 GHz |
| Primary role | RF signal analyzer | Signal source / phase noise analyzer |

Where each product wins
The N9010A wins on entry price and installed options. It is equipped with /507, /B25, /PFR, and several N9060A and N9073A measurement application options, giving you a broad toolbox if you can bring the unit back to life. The E5052B wins on condition and specialization. It is a used instrument designed for signal source and phase noise analysis, a role the N9010A does not directly claim. The price gap between the two is $32,389.
Agilent N9010A /507 /B25 /PFR EXA RF Signal Analyzer, 9 KHz to 7 GHz
This EXA analyzer is the lower-priced choice, and its installed options add measurement capabilities. The catch is that the unit comes with a repair-level condition, including system/alignment failure and system error messages, an internal measurement error, a missing front-panel 3 key, and multiple error log entries. It is sold as-is and untested, so you are buying a repair project rather than a working instrument. If you have the ability to troubleshoot and calibrate the unit, the lower price is a strong draw. Otherwise, you may spend more on repair than the unit's value.
Agilent Keysight E5052B Signal Source/Phase Noise Analyzer 10MHz-7GHz GOOD
This used unit is the higher-priced choice, but it is in used condition rather than for parts, and it is designed specifically for signal source analysis and phase noise measurements. The E5052B covers 10 MHz to 7 GHz and can be extended with an E5053A for up to 26.5 GHz, or up to 110 GHz when paired with Agilent 11970 series mixers. For engineers working with VCOs, reference clocks, or high-speed data communication jitter, this instrument is a more specialized tool. The limitation is its cost, which sits well above the N9010A's asking price.
Final choice by use case
If you are a repair-focused lab or hobbyist with the time and skills to troubleshoot a broken analyzer, the lower-priced N9010A offers an entry point into RF spectrum analysis. If you need a signal source/phase noise analyzer for production or R&D measurements and the budget exists, the higher-priced E5052B is the instrument to choose.
