2. Acquire the Signal 58 Physical Layer Bus Activity Oscilloscope waveform traces from analog channels 1 to 4 digital channels D15 to DO and the traces you see when you choose to display a bus always show the physical layer bus activi In the physical layer display bits that were transmitted earlier are to the left and bits that were transmitted later are to the right E 12C and CAN buses transmit the MSB most significant bit frst m SPI buses do nol specify a bit arder m RS 232 and LIN buses transmit the LSB least significant b frst NOTE The osciloscope displays the decode races and event tables Tor ail buses wih the MSB on the left and LSB on the right For example an RS 232 signal after the start bi might be high high high ow high low low and high Since the RS 232 protocol uses high for zero and low for one this value would be 0001 0110 Since the decode displays the MSB first the osclloscope reverses the order of the bits and displays 0110 1000 If the bus display is set to hex the value displays as 68 Ifthe bus display is sel to ASCII the value displays as h RS 232 If you defined an end of packet character lo use for RS 232 decoding the stream of bytes wil be displayed as packets When decoding an RS 282 bus in ASCII Bae O z mode a large dot indicates that the value represents a character outside the printable ASCII range MSO20008 and DPO2000B Series Oscilloscopes User Manual A
3. Use the Filet low pass filer to remove aliases from he source waveform To do this set the fiter frequency to is minimum value while zoom is off and acquisiians are running Alased frequencies are reduced to no more than 1 of their original amplitude Using a fiter frequency above the minimum can reduce but not eliminate aliasing Recognize and ignore the aliased frequencies NOTE The Nyquist frequency is one half the sample rate When the FFT is taken from a reduced resolution waveform the Nyquist requency wil be half of the reduced sample rate of the waveform not half of the full sample rate of the oscloscope Quick Tips 7 if desired use the zoom feature along with the horizontal Position and Scale controls to magnify and position the FFT waveform 7 Use the default BV RMS scale to see a detailed view of multiple frequencies even if they have very different amplitudes Use the linear RMS scale to see an overall view of how all frequencies compare to each other E The FFT feature provides four windows Each is a trade off between frequency resolution and magnitude accuracy What you want to measure and your source signal characteristics help determine which window to use Use the following guidelines to select the best window Description Window Hanning This is a very good window for measuring amplitude accuracy but less so for resolving frequencies Use Hanning for measuring sine periodic and narrow band rando
