About LINLIN (Local Interconnect Network) is a serial protocol used in automotive electronics toallow microcontrollers to communicate with low-speed peripherals. The standard wasdefined by the LIN Consortium, a group of five vehicle manufacturers. It uses a singlewire pair with a master-slave topology.The in-table view of the data looks like this:The columns in the data table are as follows:ColumnDescriptionNo.Serial number of the frame (decimal). If Accumulate mode is off,this counts from the start of the selected waveform. If Accumulate mode is on, this counts from the start of the firstwaveform in the waveform buffer.FrameLIN Bus data is divided into frames, each consisting of a number ofbits. A frame can be any of the following types:Unconditional: all subscribers must receive this frame.Event-triggered: multiple slaves may respond to this, but only ifthey have new data.Sporadic: transmitted by the master when it knows that the slavecontains updated data.Diagnostic: contains diagnostic or configuration data.User-Defined: depends on your application.Reserved: should not be used.BreakThe start-of-frame notifier.SyncA fixed value (0x55) used for automatic baud rate detection.Frame IDA six-bit value to identify the type of data carried by the frame.ParityA two-bit value calculated on the data.Data countNumber of bytes of data in the frame.Data bytesThe data content of the message.ChecksumA cyclic redundancy check of the data (hexadecimal).

PicoScope 6 User's Guide205Copyright © 2007-2015 Pico Technology Ltd. All rights reserved.psw.en r399.10Flexible powerThe flexible power system for PicoScope devices provides a choice of power sources. Inmost cases a straightforward USB connection will be enough to power the scope. IfPicoScope needs you to switch to a different powering method, it will display a dialogsimilar to this:The power icons explainedUSB 3.0 port. If this symbol appears, you may power the scope from anyUSB 3.0 port using the USB 3.0 cable provided with your scope.USB charging port. If this symbol appears, you may power the scope fromany USB port capable of supplying 1200 mA of current.Dual USB port power. If this symbol appears, you may power the scopefrom any two powered USB ports using the dual-headed USB 2.0 cablesupplied with your scope.AC adapter. Use the adapter supplied and plug it into the DC IN socket onyour scope. If you power the scope in this way, the Power Options dialogwill automatically close and the scope will start working immediately.

Reference206Copyright © 2007-2015 Pico Technology Ltd. All rights reserved.psw.en r39Insufficient USB powerIf insufficient USB power is available, PicoScope displays this dialog:Connect one of the power sources listed and try again. If you plug in the AC adapter,the dialog will automatically close and you can continue working.

PicoScope 6 User's Guide207Copyright © 2007-2015 Pico Technology Ltd. All rights reserved.psw.en r399.11GlossaryAC coupling. In this mode, the scope device rejects very low signal frequencies belowabout 1 hertz. This allows you to use the full resolution of the scope to measure a.c.signals accurately, ignoring any DC offset. You cannot measure the signal level withrespect to ground in this mode.AWG. An arbitrary waveform generator (AWG) is a circuit that can generate awaveform of almost any shape. It is programmed with a data file, supplied by the user,which defines the output voltage at a number of equally spaced points in time. Thecircuit uses this data to reconstruct the waveform with a specified amplitude andfrequency.Axis. A line marked with measurements. PicoScope shows one vertical axis for eachchannel that is enabled in a view, giving measurements in volts or other units. Eachview also has a single horizontal axis, which is marked in units of time for a scope view,or units of frequency for a spectrum view.Channel.A scope device has one or more channels, each of which can sample onesignal. High-speed scope devices typically have one BNC connector per channel.CSV. Comma-separated values. A text file containing tabulated data, with columnsseparated by commas and rows by line-breaks. CSV format is used for importing andexporting PicoScope arbitrary waveform files. You can also export PicoScope waveformsin CSV format. CSV files can be imported into spreadsheets and other programs.DC coupling. In this mode, the scope device measures the signal level relative to signalground. This shows both DC and AC components.Dead time. The time between the end of one capture and the start of the next. Toobtain the minimum possible dead time, use Rapid trigger mode.Demo mode. If PicoScope is started when no scope device is plugged in, it allows youto select a \"demo device\", a virtual scope unit that you can use to test the software.The program is then in demo (short for demonstration) mode. This mode provides asimulated, configurable signal source for each input channel of the demo device.ETS. Equivalent Time Sampling. A method of increasing the effective sampling rate ofthe scope. In a scope view, the program captures several cycles of a repetitive signal,then combines the results to produce a single waveform with higher time-resolutionthan a single capture. For accurate results, the signal must be perfectly repetitive andthe trigger must be stable.Floating inputs. A feature of the PicoScope 4225 and 4425 oscilloscopes. These areinputs that do not share a common measurement ground. The channels are separatedby high impedances and their measurement grounds can be connected to any voltagewithin the specification range. It is important however that every input in use has botha signal and a ground connection.Graticule. The horizontal and vertical dashed lines in every view. These help youestimate the amplitude and time or frequency of features on the waveform.Grid. The arrangement of viewports. The number of grid rows and the number of gridcolumns can each be either 1, 2, 3 or 4.IEPE. Integrated circuit piezoelectric. A type of sensor, usually built to detectacceleration, vibration or sound, and with a built-in amplifier. IEPE sensors can only beused with special PicoScope oscilloscopes that have IEPE-compatible inputs.

When you click a toolbar button, it will usually affect only the view that is infocus. To bring a view into focus, click on it.MSO. Mixed-signal oscilloscope. An instrument that captures and displays analog anddigital signals on the same timebase.PC Data Logger. A measuring instrument consisting of a hardware interface and thePicoLog software running on a PC. You can also use the device with the PicoScopesoftware to create a multi-channel voltage input oscilloscope.PC Oscilloscope. A measuring instrument consisting of a scope device and thePicoScope software running on a PC. A PC Oscilloscope has the same functions as atraditional bench-top oscilloscope but is more flexible and cost-effective. You canimprove its performance by upgrading the PC using standard parts from any computershop, or by purchasing a new scope device, and you can upgrade the software bydownloading an update from Pico Technology.Probe. An accessory that attaches to your oscilloscope and picks up a signal to bemeasured. Probes are available to pick up any form of signal, but they always deliver avoltage signal to the oscilloscope. PicoScope has built-in definitions of standard probes,but also allows you to define custom probes.Progressive mode. Normally, PicoScope redraws the waveform in a scope view manytimes every second. At timebases slower than 200 ms/div, however, it switches toprogressive mode. In this mode, PicoScope updates the scope view continuously aseach capture progresses, rather than waiting for a complete capture before updatingthe view.Resolution enhancement.Collecting samples at a faster rate than requested, thencombining the excess samples by averaging. This technique can increase the effectiveresolution of a scope device when there is a small amount of noise on the signal. (Moredetails).Ruler.A vertical or horizontal dashed line that can be dragged into place on awaveform in a view. PicoScope displays the signal level, time value or frequency valueof all rulers in the Ruler Legend box.Scope device. The box from Pico Technology that you plug into the USB or parallelport of your computer. With the help of the PicoScope software, the scope deviceturns your computer into a PC Oscilloscope.Standard deviation. A statistical measure of the spread of a set of samples. Thestandard deviation of the set is defined as:,whereis the arithmetic mean of all the samples. The units of the standard deviationvalue are the same as those of the original samples.Tool tip. A label that appears when you move the mouse pointer over some parts ofthe PicoScope screen, such as buttons, controls and rulers.Trigger.The part of an oscilloscope that monitors an incoming signal and decides whento begin a capture. Depending on the trigger condition that you set, the scope maytrigger when the signal crosses a threshold, or may wait until a more complex conditionis satisfied.

PicoScope 6 User's Guide209Copyright © 2007-2015 Pico Technology Ltd. All rights reserved.psw.en r39Vertical resolution. The number of bits that the scope device uses to represent thesignal level. This number depends on the design of the device, but can be boosted insome cases by using resolution enhancement.View.A presentation of data from a scope device. A view may be a scope view, an XYviewor a spectrum view.Viewport. The views in the PicoScope window are arranged in a grid, and eachrectangular area in the grid is called a viewport.
