### **Pros and Cons of buying a AVCOM PSA-35 Spectrum Analyzer**

#### **Pros**

1. **Affordability** The PSA-35 is significantly cheaper than professional-grade spectrum analyzers from brands like Rohde & Schwarz or Keysight. It offers a cost-effective entry into spectrum analysis for hobbyists, students, and small businesses.

2. **Portability** The device is compact and lightweight, making it easy to carry for field testing, amateur radio operations, or on-the-go troubleshooting.

3. **Basic but Functional Specifications** While not as advanced as high-end analyzers, it covers a useful frequency range (up to **3.5 GHz**) and provides essential features like trace storage, marker functions, and a decent display for visualizing signals.

4. **USB Connectivity** The inclusion of USB connectivity allows for data logging, software control (via included software), and easy transfer of measurements to a PC for further analysis.

5. **Good for Beginners** The PSA-35 is well-suited for those new to spectrum analysis, offering a straightforward interface and basic but practical functionality without overwhelming complexity.

6. **Amateur Radio & RF Testing** It is useful for checking transmitter performance, interference detection, and signal analysis in amateur radio applications.

7. **Decent Display & Controls** The LCD screen is clear enough for basic readings, and the controls are intuitive for manual adjustments.

8. **After-Sales Support & Community** AVCOM has a reputation for providing decent customer service, and the device has a following in hobbyist and DIY electronics communities where troubleshooting help is often available.

#### **Cons**

1. **Limited Frequency Range** At **3.5 GHz**, it is not suitable for high-frequency applications (e.g., 5G, millimeter-wave testing, or advanced satellite communications).

2. **Lower Resolution & Sensitivity** Compared to professional analyzers, the PSA-35 has lower dynamic range and resolution, which may result in less precise measurements in weak or complex signal environments.

- **Automatic frequency tracking**

- **Advanced demodulation (e.g., AM/FM/PM analysis)**

- **Built-in spectrum masks or regulatory compliance checks**

- **High-speed data acquisition for transient signals**

- **Network connectivity (Wi-Fi/Ethernet) for remote monitoring**

4. **Software Limitations** While the included software is functional, it is not as robust as professional analysis tools (e.g., Keysight s VSA or Rohde & Schwarz s Spectrum Master).

5. **Durability Concerns** Some users report that the build quality is not as rugged as higher-end analyzers, which could be a concern for frequent field use.

6. **No Calibration Capabilities** Unlike professional analyzers, the PSA-35 does not support self-calibration or advanced error correction, which may affect long-term accuracy.

7. **Limited Accessories & Upgrades** AVCOM does not offer extensive accessory support (e.g., high-power probes, specialized sensors), limiting its versatility for specialized applications.

8. **Potential for Outdated Firmware** Some users have reported that firmware updates are infrequent, which could mean missing out on performance or feature improvements.

### **Conclusion**

The **AVCOM PSA-35** is a **budget-friendly spectrum analyzer** that serves well for **beginners, hobbyists, amateur radio operators, and small-scale RF testing**. It provides a **practical introduction to spectrum analysis** without the high cost of professional equipment. However, it is **not a replacement for advanced applications** requiring high precision, wideband coverage, or specialized features.

If your needs are **basic signal monitoring, transmitter checks, or educational purposes**, the PSA-35 is a **solid choice**. For **professional RF engineering, regulatory compliance testing, or high-frequency work**, a more advanced analyzer (e.g., **Rohde & Schwarz FSEK, Keysight N9030A, or Tektronix RSA306**) would be more appropriate.

---

### **Recommendation**

- You are a **student, hobbyist, or amateur radio operator** looking for an affordable entry-level analyzer.

- Your primary use is **basic signal inspection, interference detection, or transmitter troubleshooting** within **3.5 GHz**.

- You need **portability and simplicity** without breaking the bank.

- You require **high precision, wideband coverage (beyond 3.5 GHz), or advanced demodulation**.

- You work in **professional RF engineering, telecommunications, or regulatory testing**.

- You need **long-term durability, frequent calibration, or extensive software integration**.

For those who outgrow the PSA-35, consider **upgrading later** to a mid-range analyzer (e.g., **R&S FSP, Tektronix RSA306**) when budget allows. Alternatively, if you need **even more features**, professional-grade analyzers from **Keysight or Rohde & Schwarz** are the best long-term investments.

Details:

But it'll be great for somebody WHO's into VHF UHF and all that kind of stuff. The internal battery doesn't hold a charge and I haven't actually looked at that yet But otherwise everything else seems to work fine it has nice bright display. As it turns out I need something that goes down into the lower frequency hand bands and this one doesn't have great resolution on 80 m so I'm gonna sell get a different.
