This sets the display sources for image grabbing:
Display S ource 1, 2, 3, 4
Selec t the signal for the image to display on the Display Window. In ordinary image
grab bing, the scanning image appear
Whe n grabbing images using 2 Inputs or 4 Inputs, the source signals (display sources)
are a ssigned as follows:
BW
U sually, the source signal that is obtained by performing the forward scan (left-to-right
scan) on the specimen is used to display the image. However, if you have checked the
BW check box, the source signal will be obtained by performing the backward scan
(right-to-left scan) on the specimen.
If you select Topography for Display Source 1 and 2 for measurement, for example, and
you check the BW check box (backward scan) to a display source, and you do not check
it (forward scan) to the other display source, then you can obtain the forward scan image
and the backward scan image at the same time.
You can set a bias voltage for the backward scan on the Bias Voltage tab window in
the Detailed Setting window. However, be careful that this bias voltage is only
applied for the backward scan in the Mirror scan and is not applied for measuring
the backward scan signals.
