General Oscilloscope Information
Displaying Controller Table Points -
If the oscilloscope is configured for both table and motion parameters, then the
number of points plotted across the display is determined by the time base (and
samples per division). If the number of points to be plotted for the table parame-
ter is greater than the number of points for the motion parameter, the additional
table points are not displayed, but can be viewed by scrolling the table trace
using the horizontal scrollbar. The motion parameter trace does not move.
Data Upload from the controller to the oscilloscope -
If the overall time base is greater than a predefined value, then the data is
retrieved from the controller in blocks, hence the display can be seen to be
updated in sections. The last point plotted in the current section is seen as a
white spot.
If the oscilloscope is configured to record both motion parameters, and also to
plot table data, then the table data is read back in one complete block, and then
the motion parameters are read either continuously or in blocks (depending upon
the time base).
Even if the oscilloscope is in continuous mode, the table data is not re-read, only
the motion parameters are continuously read back from the controller.
Enabling/Disabling of oscilloscope controls -
Whilst the oscilloscope is running all the oscilloscope controls except the trigger
button are disabled. Hence, if it is necessary to change the time base or vertical
scale, the oscilloscope must be halted and re-started.
Display accuracy -
The controller records the parameter values at the required sample rate in the
table, and then passes the information to the oscilloscope. Hence the trace dis-
played is accurate with respect to the selected time base. However, there is a
delay between when the data is recorded by the controller and when it is dis-
played on the oscilloscope due to the time taken to upload the data via the serial
link.
