### **Pros of the Teseq USB/P-10 CDN**

1. **High Accuracy and Compliance Testing**

The USB/P-10 CDN is designed to meet international EMC standards, including CISPR 16-1-2, CISPR 25, and others. It ensures precise measurements of conducted emissions in the frequency range of 9 kHz to 30 MHz, which is critical for regulatory compliance (e.g., FCC, CE, CISPR).

2. **Compatibility with USB Devices**

Unlike traditional CDNs that require specialized connectors, this unit is specifically designed for USB-powered devices. It eliminates the need for additional adapters or power supplies, simplifying the setup for testing USB-connected DUTs.

3. **Easy Integration with Spectrum Analyzers**

The USB/P-10 CDN interfaces directly with spectrum analyzers (e.g., Rohde & Schwarz, Keysight) via USB, allowing seamless data acquisition and analysis. This reduces wiring complexity and potential noise introduction.

4. **Portable and Compact Design**

The unit is relatively compact and portable, making it suitable for lab environments, manufacturing floors, or field testing. Its lightweight nature also reduces setup time.

5. **Supports Multiple Standards**

It is versatile for testing various USB standards (USB 2.0, USB 3.0, USB-C) and can be used for both radiated and conducted emission testing when paired with appropriate antennas and preamplifiers.

6. **Reduced Measurement Uncertainty**

High-quality shielding and precise impedance matching minimize measurement errors, providing reliable results for compliance testing.

7. **Future-Proofing**

As USB technology evolves, Teseq regularly updates its CDNs to support new standards. This unit is likely to remain relevant for upcoming USB iterations.

### **Cons of the Teseq USB/P-10 CDN**

1. **Limited Frequency Range**

The USB/P-10 CDN is primarily designed for conducted emissions testing up to 30 MHz. For higher-frequency testing (e.g., above 100 MHz), additional equipment like a preamplifier or a different CDN (e.g., for radiated emissions) is required. This may necessitate purchasing extra hardware.

2. **Cost**

The unit is not inexpensive, especially when compared to generic adapters or DIY solutions. The price may be a barrier for small businesses or individual testers with limited budgets.

3. **Specialized Knowledge Required**

Proper use of the CDN requires understanding of EMC testing procedures, calibration, and spectrum analyzer operation. Misuse can lead to inaccurate results or even damage to the equipment.

4. **Calibration Needs**

Like all precision measurement tools, the USB/P-10 CDN requires periodic calibration to maintain accuracy. Calibration services can add to the ongoing cost of ownership.

5. **Compatibility with Specific Spectrum Analyzers**

While it interfaces via USB, not all spectrum analyzers may be fully compatible. Some may require additional drivers or firmware updates, which could introduce minor compatibility issues.

6. **Limited Durability for Harsh Environments**

If used in rugged or industrial settings, the unit may be susceptible to physical damage (e.g., from drops or exposure to moisture). Teseq does not market it as a field-deployable unit for extreme conditions.

7. **Learning Curve for USB-Specific Testing**

Testing USB devices introduces unique challenges, such as handling power line noise or ground loops. Users may need additional training or resources to troubleshoot issues specific to USB emissions.

### **Conclusion**

The Teseq USB/P-10 CDN is a highly specialized and effective tool for conducted emissions testing of USB devices. Its strengths lie in its accuracy, compliance with international standards, ease of use with spectrum analyzers, and compatibility with USB technology. These advantages make it an indispensable tool for manufacturers, compliance labs, and EMC engineers who regularly test USB-powered devices.

However, its limitations such as the restricted frequency range, cost, and the need for specialized knowledge may pose challenges for smaller operations or those with limited budgets. Additionally, the requirement for calibration and potential compatibility issues with certain analyzers should be considered.

For organizations that frequently test USB devices for regulatory compliance or quality assurance, the USB/P-10 CDN is a worthwhile investment. For occasional or non-USB-specific testing, alternative or lower-cost solutions might be more practical.

---

### **Recommendation**

- You regularly test USB devices for conducted emissions compliance (e.g., FCC, CE, CISPR).

- Your workflow involves spectrum analyzers with USB connectivity.

- You prioritize accuracy and standardization in your EMC testing.

- You are willing to invest in a high-quality, long-term solution despite the upfront cost.

- Your testing requirements are limited to radiated emissions or frequencies beyond 30 MHz.

- Your budget is constrained, and you can achieve similar results with a lower-cost adapter or a multi-purpose CDN.

- You lack the technical expertise to operate the unit effectively or perform calibrations.

- You primarily test non-USB devices, as the unit is specialized for USB applications.

For users on a tighter budget, consider pairing the USB/P-10 CDN with a versatile spectrum analyzer that supports multiple interfaces (e.g., USB, GPIB, or Ethernet). Additionally, investing in training or consulting services can help maximize the unit s effectiveness.
