You are choosing between a pocket-size handheld and a used analyzer with far wider frequency reach. The TinySA-style units run on rechargeable batteries and fit in a field kit; the HP 8563E is a used analyzer that extends to 26.5GHz. The listed prices in this group are spread widely, so the right pick depends on how much frequency reach and portability you need.
Quick take
If you are working on radio boards, Wi-Fi gear, or general RF signals, the TinySA Ultra+ ZS406 and ZS407 handhelds offer a portable way to see what is happening in the spectrum. If your work goes up to microwave frequencies, the HP 8563E is the only listing here that reaches 26.5GHz, but it is a used unit and carries a much higher price than the handhelds.

Decision matrix
| Model | Best for | Consider if |
|---|---|---|
| TinySA Ultra+ ZS407 (first) | Handheld analysis with the higher-priced ZS407 listing | You want the first ZS407 option and its bundled storage |
| TinySA Ultra+ ZS407 (second) | A similar handheld experience at a lower listed price | You prefer the TinySA brand label and want the lower-priced ZS407 listing |
| TinySA Ultra+ ZS406 | An entry-level handheld with a noted 50W attenuator | You want the lowest listed price and are okay with the listed frequency range |
| HP 8563E | A used analyzer built for microwave work | You need microwave frequency reach and accept that the listing is for a used unit with no options |
Product notes
#### 4" TinySA Ultra+ ZS407 100kHz-7.3GHz Spectrum Analyzer RF Signal Generator 32GB
The 4-inch TinySA Ultra+ ZS407 with 32GB storage carries the highest listed price among the handhelds at USD 236.42. Its title advertises 100kHz-7.3GHz, and the attributes point to a built-in LNA and attenuator range of -115dBm to -19dBm. The description names 5G NR and Wi-Fi 6E as target applications. One caution: the description says Standard mode covers 100kHz-800MHz and Ultra mode reaches 6GHz, which is less than the 7.3GHz in the title. If you plan to measure near the top of that band, read the mode specifications closely before relying on the headline number.
#### TinySA Ultra+ ZS407 Spectrum Analyzer Signal Generator 4" 100kHz-7.3GHz +32GB
The second ZS407 listing is the same display class and adds 32GB storage at a lower listed price: USD 229.00. The brand label here is TinySA, and the attributes include a built-in 5000mAh rechargeable battery. It shares the 100kHz-7.3GHz title claim and the same LNA/attenuator range as the first ZS407. The same mode caveat applies: the description limits Ultra mode to 6GHz, so the 7.3GHz headline should not be treated as unconditional. For a shopper who wants the ZS407 feature set without paying the higher of the two listed prices, this is the listing to start with.
#### TinySA Ultra+ ZS406 Spectrum Analyzer 100kHz-5.4GHz 4", 2 in 1 Signal Generator
At USD 179.00, the TinySA Ultra+ ZS406 is the least expensive product in this group. The title lists 100kHz-5.4GHz, and the description highlights a 50W attenuator with 50dB fixed attenuation, plus a 4-inch TFT LCD. The battery is rated at 5000mAh and the condition is new. The listed DANL at 100MHz is -153dBm/Hz with LNA off, giving you a concrete sensitivity figure to compare. This is a reasonable starting point for someone new to spectrum analysis or for a spare unit in a field kit. The tradeoff is a listed maximum frequency below the ZS407 models.
#### Hewlett Packard HP 8563E Spectrum Analyzer 9kHz-26.5GHz RF Microwave No Options
The Hewlett Packard HP 8563E is the only used product here, listed at USD 1,299.99. Its title spans 9kHz-26.5GHz, which is well beyond the handheld units. The description states it was tested and working, and that it was pulled from a working environment. The title also notes 'No Options,' and the description says only the pictured items are included. This is a high-priced choice for a shopper who needs microwave frequency coverage and is comfortable buying a used analyzer with the caveats that come with it.
Final recommendation by use case
- New to RF work or watching your budget: the TinySA Ultra+ ZS406 is the lowest-priced listing and is described as new.
- Portable handheld and willing to spend a bit more: the lower-priced ZS407 listing gives you the same display class as the other ZS407 without the higher listed price.
- Microwave-frequency needs: the HP 8563E is the only unit here built for microwave work, but it is used, has no options, and sits at the top of the listed price range.
