Loading Data (Load)
You can load waveform data, setup data, waveform zones, polygonal zones, and snapshot waveforms that have
been saved by the instrument.
You can also view information about the saved data files using the File Property menu item.
Loading Waveform Data (Waveform)
You can load waveform data, including Math1 to Math4 waveforms. Waveform data in binary format (files with
.wdf extension) can be loaded.
File Properties (File Property)
You can display the file name (Name), data size (Size), save date (Date), attributes (Attr) and other file properties
regarding the selected file.
Loading Waveform Data into Channels (Load to Channels)
You can load the waveform data of the specified file along with the setup data into the acquisition memory. All
the data in the file is loaded.
This command is used to view or analyze waveform data that has been stored in the past on the instrument.
• You can display computed waveforms by setting the computation mode on the MATH/REF key menu to Math1
to Math4.
• Because setup data is also loaded, the instrument settings change when you load waveform data.
• Loaded data is cleared when you start measurement.
Loading Waveform Data into Reference Waveforms (Load to Ref1(Math1), Load to Ref2(Math2), Load to
Ref3(Math3), Load toRef4(Math4))
You can load the waveform data of the specified file as a reference waveform. Setup data is not loaded.
Reference waveforms are used to compare current waveforms to waveforms saved in the past and to perform
computation.
• You can display reference waveforms by setting the computation mode on the MATH/REF key menu to Ref1
to Ref4.
• If the number of data points exceeds the specified record length, the instrument samples the data so that the
number of points is equal to the specified record length and displays the sampled data.
• You may not be able to load waveform data if the memory size of the model that you used to save the
waveform data with and that of the model that you are trying to load data into are different. If the waveform
data record length is less than or equal to 1.25 Mpoints, the instrument loads the data.
• To load a file saved from the waveform data of multiple channels as a reference waveform, use Load to
Channels to load the waveform into channels, and then load the waveform as a computation
.
• The waveforms that have been acquired at the maximum record length and the waveform data that has
been acquired at the maximum record length and saved to files cannot be loaded as a reference waveform.
