Introduction
The HP35660 Dynamic Signal Analyzer is a powerful tool for measuring and analyzing signals in the frequency domain. It is capable of performing a range of measurements, including FFT, cross-spectral analysis, and coherence. The HP35660 offers high accuracy, resolution, and dynamic range, making it ideal for many applications, including audio testing, vibration analysis, and noise characterization.
One of the key strengths of the HP35660 is its ability to automate testing. Automated testing enables faster and more efficient testing, and reduces the likelihood of errors in measurement. In this paper, we will discuss the components and setup required to build a frequency-domain automated testing system using the HP35660.
Components of a Frequency-Domain Automated Testing System
To set up an automated testing system using the HP35660, several components are required. These include:
1. Signal generator: A signal generator is used to produce signals of known frequency and amplitude. The output of the signal generator is connected to the input of the device under test (DUT). The signal generator should be capable of producing a range of frequencies and amplitudes suitable for the DUT.
2. Amplifier: In some cases, the signal generated by the signal generator may not be strong enough to adequately drive the DUT. In such cases, an amplifier can be used to boost the signal.
3. Device under test (DUT): The DUT is the device being tested. Its output is connected to the input of the HP35660.
4. Cabling: High-quality cabling is required to connect the various components of the testing system.
5. HP35660 Dynamic Signal Analyzer: The HP35660 is the instrument used to perform the measurements. It is connected to the DUT and is used to measure the response of the DUT to the input signal.
6. Computer: A computer is used to control the HP35660 and to automate the testing process.
7. Automated testing software: Automated testing software is used to control the HP35660 and to perform the measurements. The software should be capable of generating test sequences, controlling the signal generator, and analyzing the data generated by the HP35660.
Setup of a Frequency-Domain Automated Testing System
To set up a frequency-domain automated testing system using the HP35660, the following steps should be taken:
1. Connect the signal generator to the DUT using high-quality cabling.
2. If necessary, connect an amplifier between the signal generator and the DUT.
3. Connect the output of the DUT to the input of the HP35660 using high-quality cabling.
4. Connect the HP35660 to the computer using a suitable communication interface.
5. Install the automated testing software on the computer.
6. Configure the automated testing software to control the HP35660 and to generate the required test sequences.
7. Run the automated testing software to perform the measurements.
Advantages of a Frequency-Domain Automated Testing System
A frequency-domain automated testing system offers several advantages over traditional manual testing methods. These include:
1. Efficiency: Automated testing is significantly faster than manual testing. It eliminates the need for manual adjustment of the signal generator and the HP35660, enabling tests to be performed more quickly and with greater consistency.
2. Consistency: Automated testing eliminates the variability associated with manual testing, resulting in more consistent and accurate measurements.
3. Accuracy: Automated testing ensures that the HP35660 is configured correctly and that measurements are performed in accordance with the test plan.
4. Record-keeping: Automated testing software can be used to record test results, making it easier to analyze the data and to identify trends over time.
Conclusion
The HP35660 Dynamic Signal Analyzer is a powerful instrument that can be used to perform a range of measurements in the frequency domain. Automated testing using the HP35660 offers significant advantages over traditional manual testing methods, including increased efficiency, consistency, accuracy, and record-keeping. To build a frequency-domain automated testing system using the HP35660, several components are required, including a signal generator, amplifier, DUT, cabling, HP35660, computer, and automated testing software. With a properly configured testing system, it is possible to perform efficient and accurate testing that enables the identification of problems and the optimization of device performance.
