Datalog Waveform Selection Window
If you see the message “No Waveform” as shown in the figure
above, the file does not contain any waveforms that can be
displayed. Possible reasons are:
• The loaded file is not a Datalog file.
• You are not permitted to read the file. Ensure that you have read-
permission.
To use one of the available waveform display areas, activate the
corresponding checkbox S
ELECT WAVEFORM #1, #2, or #3.
Data Selection A Datalog file can contain many waveforms. The Data selection
boxes at the left-hand side provide browsers to make the data
selection easy.
If you choose the name of a test suite from the list, then all
further selections will be restricted to that suite.
If you, for example, select a DAC Distortion suite, the Test Names
will be restricted to “captured waveform”, “processed waveform”,
and “FFT” data, and only defined pins will be available.
T
EST NAME: If you choose the name of a test from the list, then all
further selections will be restricted to that test.
P
IN NAME: If you select a certain pin, only waveforms referring to
that pin will be available.
W
AVEFORM: If you have not made a preselection via Suite Name,
Test Name, or Pin Name, you can choose from all waveforms
contained in the Datalog file.
