The processing web also supports measurements. Repeat this to add a preview to the output of the difference icon. It is showing a view of the waveform coming from the ERES function. A preview box will open attached to the ERES output. Press the Add Preview button in the Web Editor dialog box. Touch the output arrow of the ERES icon, it will turn green. The Web Editor after ‘wiring the math operation Touch or click on each of the math operator icons and drag them to the approximate positions shown in Figure 6. Note, that unlike the math function traces which are limited to at most two operators, the processing web has no limit on the number of operators as long as you have enough processing memory. These are the three math functions we need to create the high pass filter. Use the Add Math button to add the Difference function. The bandwidth of the ERES filter is a function of the effective sample rate and we want to reduce the 20 GS/s sample rate to 100 MS/s to reduce the bandwidth to the range of the 5 MHz fast edge signal we are using as a source. The sparse function is used to reduce the effective sampling rate of a waveform.

Use the Add Math button again to add the Sparse function. It will be highlighted and the right hand tab of the Web Editor dialog box will show the controls for the ERES math function as shown in Figure 5. Touch or click the ERES math icon in the Web Editor. Pressing the Add Math button evokes the math function scroll list, select ERES, and the ERES math icon appears in the Web Editor Scroll to the ERES entry and touch or click on it to open the ERES math function in the Web Editor as shown in Figure 5. The math operator scroll list should appear. In our example we will use the ERES filter and some simple math to create a high pass filter in the F1 math trace.įrom the Web Editor tab press the add math button. ERES applies a finite impulse response (FIR) digital low pass filter with the bandwidth of the filter set by a user selection of the number of bits of enhancement in a range of 0.5 to 3 bits in 0.5 bit steps. LeCroy oscilloscopes include a digital low pass filter math function called Enhanced Resolution (ERES). The Measure tab similarly allows the user to set the function of any of the measurement parameters to be a simple measurement, parameter math, or the web edit. This is indicated by the F1 terminal being on the right had side of the Web Editor in Figure 4. Note that we have already set F1 to be the output from the processing web. The Math tab allows the user to set the function of any other the math traces to single operator, dual operator, histogram, or web edit.

There is also a button which adds Previews, these are viewing windows that show the waveform or measured value at the output of any operation. The Web Editor dialog has buttons that will add math, measurements, or parameter math functions as shown in the left side in Figure 4. The Processing Web Editor uses a graphic interface to allow a user to create complex math and measurement parameter functions that use multiple single operations combined in various ways. The scope display should be similar to Figure 2. Adjust the vertical scale of channel 1 to maximize the C1 signal amplitude on the display. Set the vertical scale to variable gain by checking the Var Gain checkbox.

Set the channel 1 signal amplitude using the C1 dialog box.Auto Setup the scope: Press Scope Setup then select Auto Setup from the fly-out menu.The Fast Edge signal is a 5 MHz, 450 mVp-p, square wave. Utilities pull down > Utilities Setup >Aux Output Tab>touch or click on Fast Edge. Set up the Aux output to be the Fast Edge signal.Set the input coupling on Channel 1 to be 50 Ohms: Touch or click the channel 1 annotation box>touch or click on the coupling field >select DC 50 Ω.Recall the default setup: File pull down > Recall Setup> Recall Default.

Connect a coaxial cable from channel 1 to the Aux connector on the front panel.Equipment Requiredĭisplays shown in the tutorial are based on the following initial setup on a WaveRunner 6 Zi scope: The processing web supports using multiple math and measurement operations within a single math trace. The icon in the lower part of the screen says the processing web will find the “max” of the averaged FFT’s and send this result to parameter P11 A preview window shows this average which is also sent to trace F1. The waveforms acquired in channel are set up to have an FFT performed on them, then an average of the FFT’s.
