shown in the top-right corner of the Soft Front
Panel is information about the PXI module being controlled by this
Soft Front Panel. This information cannot be changed through the
Soft Front Panel.
Stop Button
This button is used to stop the Soft Front Panel from
reading and writing to the PXI module; it halts the program and is the
preferred way to exit the program.
IF ATTEN 1 (dB)
This slide control (along with an entry box) is
used to select the level of IF attenuation and may be changed by
pointing to the slide control and dragging it up or down to select
N O T E
System gain is a combination of the settings for IF ATTEN 1 and IF ATTEN 2.
Using both attenuators will result in better system performance. For optimum
performance, the factory recommends that when adjusting the IF attenuators of the
PXI-1420, the adjustment should be made so that no part of the IF chain is overloaded.
To prevent overloading during an adjustment, first adjust IF ATTEN 2 from 0 to 20 dB,
and then adjust IF ATTEN 1 until reaching the desired attenuation.
