Spectral Scan Probes Tab
Select and activate the probes under the DUT. You can
activate the probes by either a left click on individual cells or
by left clicking and dragging the mouse and choosing Select
Cells; or clicking on Select All to activate all of the probes.
Green indicates the activated probes.
You can deactivate the probes; either left click on already
selected cells or by left clicking and dragging the mouse and choosing Unselect Cells; or by clicking on

Amplitude Adjustment Tab
You can use an LNA or attenuator with EMxpert to increase
or decrease the power level of the signals coming from the
scanner and going to the spectrum analyzer. To activate
click on Amplification Setting or Attenuator Setting and
then select the value from the drop down menu or type the
value. The displayed value of the signal will be corrected
for the value of the gain or attenuation.
Internal Analyzer Pre-Amp:
This feature provides extra
sensitivity. It is ON by default. Turn this feature OFF if your
spectrum analyzer is not equipped with a Pre-Amp.
