Waveform Measurement 

To  enable  the  waveforms  to  be  measured,  pairs  of  voltage  and  time  cursors  can  optionally  be 
overlaid on the Waveform display, so the first step is to display these cursors.  

These cursors may be moved using the HORIZ and VERT knobs or by dragging with a mouse. 
The cursor that is moved by the knobs is the one currently shown in  yellow. Pushing the knob 
switches control over to the other cursor.

 

A read-out  showing the current  positions of the cursors and their separation  is  displayed in  the 
top right-hand corner of the screen. 

Control Panel 

Mouse & Keyboard 

To display the cursors: 

 

To select which cursors are displayed, tick the required cursors in the Properties control.

 

 

Toggle between displaying and hiding these cursors either by ticking and clearing the 

Show 

Cursors

 option in the Properties control or by selecting the 

Cursors

 option from the Button 

Bar (highlighted when the cursors are displayed).

 

Shared Waveform Markers 

To  aid  comparisons  across  multiple  waveforms,  the  OTR  allows  you  to  define  one  or  more 
additional  ‘Shared  Waveform  Markers’  that  occupy  the  same  custom  positions  across  all 
waveform displays. 

The  Waveform  Markers  are  set  up  either  through  the  Shared  Waveform  Marker  section  of  the 
View window Properties Control or

, 

where a mouse and keyboard are fitted, through the Right-

click  menu.  Additional  Time  markers  and  Amplitude  markers  can  be  set  up,  positioned  and 
removed both using this section of the Properties Control and from the Right-click menu. 

The display of the markers on any particular Waveform tile is controlled separately through the 
Cursors  section  of  the  Waveform  Properties.  Here  their  display  is  controlled  both  through  a 

Shared markers

 option that needs to be ticked, and the same overall 

Show Cursors

 option used 

to toggle the display of the pairs of measurement cursors.
