![]() Touch or click the Timebase annotation box on the display of the oscilloscope.Connect the ground lead of the probe to the ground connection on the WS-100 as shown in Figure 1. Connect one passive probe to Ch2 of the scope and Ch2 of the WS 100.Connect one passive probe to Ch1 of the scope and Ch1 of the WS 100.If the Found New Hardware Wizard appears press the cancel button. Connect the WS 100 to a front panel USB connector.Press the Normal button in the Trigger area on the oscilloscope’s front panel.Set up the trigger as follows: Edge-Trigger, Source :C1, Coupling : DC, Slope: Positive, Trigger Level: 2.5 V Touch or click the Trigger annotation box on the display of the oscilloscope.Using the C1 dialog box of the front panel vertical scale control, set the channel 1 vertical scale to 1 V/division and the vertical offset to -3V.Verify that the input coupling on both channels 1 and 2 is DC 1 M: Touch or click the channel 1 annotation box>touch or click on the coupling field >select DC 1M.Recall the default setup: File pull down > Recall Setup> Recall Default.The Signal Outputs Available from the WS 100 Demonstration Signal Sourceĭisplays shown in the tutorial are based on the following initial setup on a WaveRunner 6 Zi scope: In this tutorial we will use selection S2 (I2C). Table 1 summarizes all the available outputs. There are two sets of duplicate output connections on the WS 100 which are marked Ch1, CH2, and Trig. The WS 100 signal source is a USB powered circuit board which has 6 sets of output waveforms. Note: Although a specialized signal source is used in the following tutorial the explanations of how to set up measurements and interpret the results should be useful to WaveSurfer users who have other signal sources. WaveSource 100 demonstration signal source Equipment Requirements:Ī LeCroy WaveSurfer Xs-B series oscilloscope with the I2C option keycode installed. This tutorial will get you familiar with the LeCroy I2C Decode & Trigger Option. The slave responds with an acknowledge bit (ACK). Data transfer is initiated by the master with a start bit followed by the address of the desired slave and a read/write bit signaling that it wants to read from or write to the slave. Slaves are addressed using unique address codes which can be in a 7 or 10 bit format, multiple masters can be used in a single I 2C system, each with a unique address. I 2C uses two bidirectional lines with clock (SCL) and data (SDA) signals. I 2C is a master/slave synchronous communications system developed by Phillips with rates of up to 3.4 Mb/s. Inter Integrated Circuit (Inter IC or I 2C)
