Analyzing Wavef
orms
Different window functions produce different filter response shapes in the spectrum and result in different resolution
bandwidths.
The resolution
bandwidth directly controls the gate w idth. Therefore, the time domain gate markers move as you
adjust the RBW control.
You can display the linear magnitude of the real data or the imaginary data in the spectrum. This is useful if y ou process
the spectrum off line and transform it back into a time domain trace.
Using Mask Tes
ting
Serial Mask Testing (Option SM) allows you to compare your signal to a predefined template or mask. For the signal to
pass the test, it must fall outside the segments defined by the mask. Generally, standards committees such as ANSI
define the masks. To perform mask testing do the following:
1. Select Masks > Source....
2. Select the signal source.
3. Click the Masks tab.
4. Select the Type and Standard.
