How to correctly select the reference source in DSA8300 TDR impedance test?
There are several key factors to consider when selecting a reference source in a DSA8300 TDR impedance test:
Output Impedance: The output impedance of a TDR is usually a 50 ohm standard resistor. Therefore, when selecting a reference source, it is important to ensure that its output impedance matches the output impedance of the TDR device to avoid signal reflection and loss.
Signal wavelength: TDR testing requires the use of high-speed signals and the signal wavelength should be much smaller than the size of the device to be tested. This means that the signal frequency of the reference source should be high enough to ensure that a short enough waveform can be captured for effective impedance analysis.
Signal Integrity: The DSA8300 has excellent bandwidth, signal fidelity and modular architecture for high performance TDR and interconnect analysis. Therefore, when selecting a reference source, its signal integrity and stability should be ensured to guarantee the accuracy of test results.
Therefore, when selecting a reference source, consider using a low-pass test mode for more information on impedance characteristics.
How do I set up and optimise the incident waveform display in a DSA8300 TDR impedance test?
Setting up and optimising the incident waveform display in a DSA8300 TDR impedance test can be done in the following steps:
Select the appropriate measurement parameters:
Ensure that you have selected the appropriate measurement parameters, such as bandwidth, rise time, etc. The DSA8300 supports bandwidths up to 50 GHz, with a suppression rise time of 15 ps and an incident rise time of 12 ps.
Configure the oscilloscope:
In the DSA8300 user interface, go to the ‘Oscilloscope’ settings section and adjust the vertical and horizontal resolution to ensure that the details of the incident waveform can be clearly captured.
Optimise the waveform display:
Use the ‘Waveform Capture’ function to record the incident waveform, the DSA8300 provides a variety of waveform capture options, you can choose the most suitable capture method according to your needs.
Use the ‘Pulse Restore’ function to calibrate the time axis to ensure the accuracy of the waveform data.
Reduce noise and jitter:
Reduce noise and jitter during testing with the ‘Jitter’ and ‘Noise’ processing functions to improve the clarity and accuracy of waveforms.
Use the Mask function:
Use the Mask function to further optimise the waveform display by setting different levels of masking to highlight important waveform features.
