  • Page 5: Wavepulser Approach

    INTRODUCTION WavePulser Approach Pulser/ Pulser/ Pulser/ Pulser/ Sampler Sampler Sampler Sampler WavePulser uses time domain reflectometry to characterize a DUT’s elec- trical behavior by stimulating the DUT with impulses and measuring reflec- tion and transmission. Once a measurement is configured, all phases Internal Calibration Reference Plane proceed without any user intervention whatsoever.

  • Page 16: Basic Configuration

    BASICS Basic Configuration The Setup dialog contains all the basic settings required for making any type of meaurement. See the WavePulser User Manual for detailed instructions on using these settings. Choose Setup from the menu bar to open the dialog. Set Up Acquisition As you modify the End Freq and Num Points, you'll notice the values for Delta Freq and Time Length change.
  • Page 17 BASICS Configure Ports If you've connected single-ended inputs to the same number port on the WavePulser as on the DUT (1 to 1, 2 to 2, etc.), and none of the ports have been skipped, you need only enter the Num(ber of) Ports in use. If you wish to calculate mixed-mode S-parameters or change any port assignments, click + to expand, then check Enable and click Configure.

  • Page 18: Advanced Configuration

    BASICS Advanced Configuration The following settings are optional. If your test setup calls for them, click the + button to expand the Setup dialog. You can apply these settings following acquisition, then just Recalculate the results. See the WavePulser User Manual for more information on using these features. Physicality If you wish to used saved calibration data or are using the external Cal Kit, click the Calibration button and set up Manual calibration.

  • Page 19: Viewing Tdr/Tdt Waveforms

    BASICS Viewing TDR/TDT Waveforms Raw, uncalibrated TDR/TDT waveforms can be acquired and displayed as either an impulse response or step response for a crude impedance profile. Because they respond quickly to manipulation of the DUT, TDR/TDT traces are also useful for checking signal integrity at different points on the circuit. Turn Pulse On for each port to which to send the pulse, then turn Trace On for each port from which you wish to view the response.

  • Page 20: Viewing Frequency Domain Results

    BASICS Viewing Frequency Domain Results Using the measurements calculated from the calibrated TDR/TDT waveforms, the WavePulser application generates Result traces (Sn), which plot a single S-parameter measurement. Result traces can be analyzed with standard tools such as Cursors, Measure and Math, or used as inputs to SI Studio. Go to WavePulser Setup >...

  • Page 21: Viewing Time Domain Results

    BASICS Viewing Time Domain Results Time domain results are displayed using the same procedure as for frequency domain results. Optionally, click the Config button to smooth the trace by increasing rise time or applying SinX/X upsampling, or to change the x-axis units from Time to Distance. Time results Impedance Profile, Step Response, Impulse Response, and Rho.

  • Page 22: Viewing The Smith Chart

    BASICS Viewing the Smith Chart You can display an Admittance Smith Chart of any two calculated or imported S-parameters simply by selecting them from the Smith Chart dialog. Optionally, modify the chart by changing the frequency range plotted (the full range of the last measurement is the default), or display Result traces alongside the Smith Chart by changing the Smith Chart Display selection.

  • Page 23: Calculating Loss (Delta-L)

    Calculating Loss (Delta-L) The Delta-L feature applies the Intel Delta-L loss characterization method to calculate loss (in dB) per unit length of a PCB trace without calibrating at the ® end of probe tips. It can be calculated from a new acquisition or saved S-parameters. Simply enter the electrical lengthof the DUT and the frequencies at which to calculate.

  • Page 24: Importing S-Parameters

    BASICS Importing S-Parameters You can import external S-parameters on the SParam Import dialog and view the S-parameters as different Result traces, only in this case, the traces are labeled Rn on the display. Browse to and select the Touchstone file, then follow the same procedure as for displaying internal results (p.18-19). Import files should be in Touchstone 1.1 format, the same in which the WavePulser saves files.

  • Page 25: Exporting S-Parameters

    BASICS Exporting S-Parameters The Touchstone files are saved in the Magnitude and Frequency Format selected on the SParam Export dialog. The default format is Magnitude/Angle in MHz. You can also use this dialog to save the latest calculated S-parameters on demand.

  • Page 26: Working With Result Traces

    BASICS Working With Result Traces Trace Descriptor Boxes Descriptor boxes appear along the bottom of the grid area when a trace is turned on, summarizing the current settings of the traces they represent. They are color-coded to the trace. Clicking the descriptor box is a shortcut to the rescale dialog for that trace.
  • Page 27 BASICS Zooming Traces Zooming allows you to "zoom in" on waveform details or "zoom out" to see a greater span of acquisition. There are two principal ways to zoom a trace. Rectangle Zoom New Zoom Trace Click-and-drag diagonally to draw a rectangle around the part of the Zoom traces (Zn) display a magnified portion of another trace.

Not only can you choose the type of cursor to apply, you can choose which set of values are displayed for each cursor position.

  • Page 29: Measurements And Statistics

    BASICS Measurements and Statistics Math Measurements are waveform parameters that can be expressed as Math creates a new Function (Fn trace) that displays the result of numerical values, such as amplitude or frequency. You can measure applying a mathematical operation (e.g., Sum, Product, FFT) to one or up-to-eight parameters on various traces and view the active readout in more source traces.
