1. View signal Names,values and more : Key CTRL
Shows all signal values and other properties
-> see "Key CTRL Options", next section below
- Key CTRL: if mouse cursor is close to signals, only from this signals
- Key CTRL: if mouse cursor in free place, all from values
- Key Shift, then key CTRL: to select from desired signals, hold down key shift, move mouse cursor over desired signals, release key shift and press key ctrl (don't move mouse during release key shift and press key ctrl).
- Left mouse button while holding down key CTRL writes signal names
- Right mouse button while holding down key CTRL, centers to vertical position
- "CTRL-Double-key-down" (short release of key CTRL) in 0.5s only shows values (if time info is selected, then time info as well)
2. Key CTRL Options
Holding Key CTRL down and press <ENTER>:
Options window appears for several view options:
- Values
- Unscaled values (no mathematical functions, raw data)
- Signal names and channel numbers
- Math. functions and/or scaling factors
- Time info (duration): how long is a signal not changing (TCV); usefull especially for boolean signals
- X vector value
- Gradient value dy/dx; usefull especially in "separated view" to check the gradient of signals
- Start point for calculation is the mouse position on "Key CTRL down" or on "Mouse click".
- Y step (Jumps,Delta Y)
jump is the value difference to the last value, if value is changing because of mouse moving in horizontal direction
The order of the checkboxes can be changed:
- on checkbox: hold mouse button down and move mouse
- or select checkbox and using Key ALt-ArrowUp, ArrowDown
Others:
"Labels with background color" allows inverted label colors using key Ctrl (probabely better view)
"Text distances" using key Ctrl, the text positions (top,left) can be changed
"Last part of name ..." if checked, it shows only the part of the string after the defined separator (character or string).
Option: If you want to display only the last 25 characters of the signal names, you can write: "=25".
If names are shortened, the beginning of signal names are indicated with the tilde " ~ ".
Example (separator is '.' ):
Original name is: MWT.ZYL_Load_ZYL_Load_Ctrl.ZYL35_Wft_load_Ctrl
Reduced name will be: ~.ZYL35_Wft_load_Ctrl
This helps to reduce long names for better visibility.
3. Key F2
- Move mouse to signal line
- Press F2
- Select signal
-
a) Now you can position signal Name
or
b) You can press right mouse button for more options (see graphic)
Gradients and distances
4. Gradients : Key F3 / F4
Move mouse to desired position, press key F3;
move mouse horizontal or vertical for desired distance measurement then press F3 again or left mouse button
- Alt-F3 or Alt-"left mouse button" takes result value from blue field
F4 shows the cathets of the gradient as well.
Changing between gradient with oor without cathets:
F3 - ESC or F4 - ESC
5. Distances : Key F6
Move mouse to desired position, press key F6;
move mouse horizontal or vertical for desired distance measurement
- then press F6 again or left mouse button
- Alt-F6 or Alt-"left mouse button" shows frequency as well
About distance measurement:
Distances in the x vector direction can be determined in 3 different ways
A: with key F6
Disadvantage: not as accurate, since the pixels are measured, and the scaling factor is used to calculate the distance (pixels, image scaling
and zoom factor) . But in most cases sufficiently precise.
B: If the value panel is active, the distance is taken directly from the data base at the mouse cursor position; precise
value.
C: If the CTRL key is pressed, the distance is taken directly from the data base at x vector position; precise value.
However, this option must be activated (CTRL-ENTER opens the activation panel)
If mouse cursor is close to signal line, press key F7 and select signal and move it to the desired position.
Instead of signal name, the data of the function will be displayed (Date/Time, time constant, asymptote).
In the selected x range, the signal must be a continuous exponential function!
Calculation formula:
Given are then points t0, t1, t2
with the values y0, y1, y2
Condition: t1-t0 = t2-t1 (t1 is in the middle of t2, t0)
z = y1^2 - y2*y0 n = 2*y1 - y2 -y0
Aymptote y = z / n
Time constant = (t0 - t1) / ln((y1-y)/(y0-y))
Statistics of data will be made from the actual x vector zoom range, only with selected signals, and with connections as well.
Right mouse button opens pull down menu with more options.
8. Summary of other important key functions in graphic window
HELP : Key F1
Write search string and click on button "List"
Click on desired entry -> help function jumps to description
Repaint graphic : Key ALT-R
Press key ALT-R or only R to repaint graphic (in case of fragments)
Last Graphic zoom : Key ALT-L (or key L) Very usefull key!
After zoom in or zoom out, you can go back to last zoomed settings.
The last 20 settings are saved.
(Opposite function is "Alt-N")
With this you can multiple zoom out to see details in then graphic and go back with key "ALT-L"
View signal Names,values and more : Key CTRL, Key ALT
Shows all signal values and other properties
-> Key CTRL: if mouse cursor is close to signals, only from this signals
-> Key CTRL: if mouse cursor in free place, all from values
-> Key Shift, then key CTRL: to select from desired signals, hold down key shift, move mouse
cursor over desired signals, release key shift and press key ctrl
(don't move mouse during release key shift and press key ctrl).
-> Left mouse button while holding down key CTRL writes signal names
-> Right mouse button while holding down key CTRL, centers to vertical position
-> "CTRL-Double-key-down" (short release of key CTRL) in 0.5s only shows values
(if time info is selected, then time info as well)
-> ALT-key is pressed and mouse cursor is close to a signal, the value of the
signal will be taken and calculated in the math panel ("RESULT" is signal value
and the output of formula is displayed in the blue field).
-> CTRL-key left/right moves line with values pixel by pixel
usfull for exact positioning and compare values
Signal View Options
Press Key CTRL-ENTER
-> select options and move view positions with holded mouse button down to your desired position
Signal Names : Key F2 for labeling signals
If mouse cursor is close to signal line press key F2 and select signal
- "ALT-F2" -> Only value of signal
- "CTRl-F2" or "CTRL - Right mouse button" -> with additional TCV information
- TCV = TimeConstantValue => Shows how long the signal has the same value at the current x position)
Full Y vector range : Key CTRL-Y
Full protocol in vertical direction (only selected signals)
Full X vector range : Key CTRL-X
Full protocol in horizontal direction (full x vector range)
Full Graphic : Key ALT-F or F (or key F)
Full view in x and y vector directions
Delete Signals from graphic
To select desired signals,
- hold down key shift,
- move mouse cursor over desired signals
- release key shift
- press key DEL (Delete)
(don't move mouse during release key shift and press key DEL).
Binary signals positioning
In normal mode (not separted or grouped), move mouse cursor to y vertical position and press key INS (insert)
Mathematical functions
In mathematical panel (yellow field) you see a technical calculator; it can be used normal as calculator (e.g. 15.3/pi-sin(2*pi*30)
In case of a string "RESULT" in formula, "RESULT" is the value of actual or last measurement (distance (F6),
gradient (F3); the calculation result is in blue field.
In case of ALT key is pressed, value of signal close to the mouse cursor is the result of the calculation you see in blue field.
