6.4.3 Oscilloscope Functionality
Overview
The Oscilloscope in the IMST is a Java applet designed to detect user-defined control or drive signals and to display them in a scaled grid. These signals are configured using the options available to the right and below the grid.
The oscilloscope is available only if the relevant Internet Explorer settings are made (refer to chapter 5.2 "Browser Settings" on page 39 for details). The current user has to have viewing and modifica‐
tion rights as well to use the oscilloscope.
The oscilloscope applet window contains the following areas:
● Main graphical display area with x-y grid
● Signal details on detected recordings just below the x-y grid
● Tabs to configure the measurement and for signal triggers
Using the IndraMotion Service Tool
● Tabs for scaling and color selection
● Active measurement to configure signals
Fig.6-15: Initial applet for the oscilloscope function
Increase the viewing area of the oscilloscope by hiding the naviga‐
tion tree structure. Click the "Tree icon" to hide the naviga‐
tion tree structure. Click the "Tree icon" again to display the tree structure.
Graphical Display Area
The signal display area contains a x-y grid with the following properties:
● The x-scale (horizontal) and the y-scale (vertical) are calculated dynami‐
cally based on the minimum and maximum values of the signals and the time period intended for measurement
● The y-measurement is displayed from minimum to maximum signal value.
Resizing the Explorer window dynamically scales the detected recordings and increments the x-y units
● Signal scaling can be increased or decreased using the scaling options
● Signal units are displayed in the upper left and lower right of the display area

Configuring Measurement and Signal Trigger
Configuring measurement
The "Confg Measurement" tab is used to configure the number of measure‐
ments to be taken and the recording period in ms. The actual recording period is write-protected and is calculated by multiplying the "Number of Samples" with the "Time Period".
Using the IndraMotion Service Tool
Fig.6-19: Configuring measurement Signal Trigger/Manual Trigger
The "Signal Trigger" tab is used to configure the settings for a "signal trigger"
or a "manual trigger". The Configure button is used to select the trigger type, pretrigger and source parameter to be analyzed.
A. Tab changes to "Signal Trigger" when the trigger type is set by pressing the Configure.
B. Tab changes to "Manual Trigger" when the trigger type is set by pressing the Configure.
Fig.6-20: Signal and manual trigger configuration
Click on the Configure button proceed as follows to configure a trigger:
1. Select either the Manual Trigger or the Signal Trigger button.
A signal trigger requires additional configuration starting at step 3.
2. Enter a value in percent for the Pre Trigger and Post Trigger fields.
3. Click on the Select button and select the parameter to be used as trigger.
4. Select the Trigger Edge to be used for the selected parameter.
5. Enter a value in the Trigger Value field that is used to start the Oscillo‐
scope.
The fields in the "Trigger Value" section change based on the selected parameter in step 3.

6. Click OK to complete the trigger configuration.
Numerical parameters The selection of a numerical parameter (float or integer) displays the current value, units and trigger value. The trigger value is defined in the "Trigger Val‐
ue" field.
Binary or hexadecimal parameters Selecting a binary or hexadecimal parameter allows the setting of a binary trig‐
ger by defining a trigger mask. Selecting the Bit Trigger checkbox allows to define the transition of a single bit. The value is determined by selecting the relevant checkboxes or radio buttons.

Detecting Recording with the Oscilloscope
Once all relevant signals and triggers are configured, the signals are ready for detection. Proceed as follows to detect the recordings from the selection sig‐
nals.
Using the IndraMotion Service Tool
1. Click on Start in the "Active Measurement" tab.
If the signal trigger is set to "Manual Trigger", click on the Trigger Man‐
ually button to detect and display the recordings.
A signal trigger detects the recordings when the conditions configured in the "Signal Trigger" tab are met.
2. Once all recordings are detected and displayed, the recordings can now be edited using the tools available on the "Scaling/Color" tabs and the measured signals specified just below the recordings.
Editing Oscilloscope Signals
Overview
Once all oscilloscope recordings are detected and displayed, the recordings can be edited as follows:
● Display and hide recordings
● Scale and shift the recordings to the x-axis
● Zoom in the x-axis using an incremental zoom function or selecting a spe‐
cific area using the cursor function
● Display the recordings using the following options:
– Interpolated measuring points – Real measuring curve
– Single measuring points
● Change color of each recording
Measured Signals (Displaying Recordings)
Detected signal recordings are shown or hidden by enabling or disabling the checkbox on the left next to each signal. The currently selected signal is high‐
lighted in the table and displayed with a recording printed in bold. The recording of the remaining visible signals is more detailed. The measuring units on the y-axis is adjusted to the selected recording. The x-y-axis always measures time in ms.
Fig.6-23: Displaying measured signals
Number of supported channels The number of signals that can be measured at a time depends on the selected device. IndraMotion MLC and IndraLogic XLC always support 16 channels.
IndraDrive drives support four channels.
Recording Color Each recording along with its measuring unit is assigned to a matching color that can be modified by selecting the "Color" tab on the right next to the graph‐
ical display area. Ensure that each recording has a unique color assigned.
Additional columns when using os‐
cilloscope cursor function The measured signal table displays additional columns when using the cursor function of the oscilloscope available in the "Scaling" tab. If this cursor function is used, the "Y Cursor Diff" and "X Cursor Diff" columns appear in the table.
Using the IndraMotion Service Tool
Fig.6-24: Additional columns when using the cursor function Y-Scaling
The oscilloscope recordings are scaled sing the options available on the "Scal‐
ing" tab. Only the currently selected recording in the "Signal" table is scaled.
Fig.6-25: Scaling on the y-axis
Clicking the minus button ( - ) decreases the increment of the y-axis causing the current signal to extend in y-direction.
Clicking the plus button ( + ) decreases the increment of the y-axis causing the current signal to reduce in y-direction.
Clicking the up arrows (↑) shifts the active signal up by 10 %.
Clicking the down arrow (↓) shifts the active signal down by 10 %.
The last two buttons with a curve image are used to change the amplitude of all signals as follows:
● The first amplitude button from the left changes the amplitude of all signals to use the full range of the display (i.e. the signals are stretched along the y-axis)
● The second amplitude button changes the amplitude of all the signals based on the largest signal (i.e. the signals are compressed along the y-axis)
Zoom
The buttons in the "Zoom" section of the "Scaling" tab are used to zoom in and out and affect all the recordings in the display at once.
Using the IndraMotion Service Tool
Fig.6-26: Zoom function for recordings in the x-Axis
Zoom out Clicking the minus button (-) decreases the increment of the x-axis causing all the recordings to extend in x-direction.
Switching off zoom The one-to-one button (1:1) becomes active when a zoom button (+/-) is clicked.
This returns the recordings to their original size.
Zoom in Clicking the plus button ( + ) increases the increment of the x-axis causing all recordings to be decreased in x-direction.
Showing cursor
The Show cursor button is used to select a specific curve segment by creating a frame around the segment with two sets of perpendicular lines. The cross section of all four lines is the important point. Each line can be positioned by clicking and dragging each line to the desired position until a box is created around the relevant area. The mouse pointer changes to a two-headed arrow line (↕) when positioned on a line.
