1.5 Waveform Display, Automatic Saving of
Measured Data, File Conversion, and Other
Functions
The following functions are common to all measurement modules controlled by the
WE7000 Control Software. For details, see the WE7000 User’s Manual (IM 707001-
01E).
Controlling the Timing of Measurement Start (Arming)
You can control the measurement start timing using the arming signal which is set in the
Trigger Source/Time Base Source/Arming Setting dialog box. When the measurement
module is connected to the arming signal (ARM) bus in the Trigger Source/Time Base
Source/Arming Settings dialog box, the arming signal enters a wait state when the user
clicks the Start button in the operation panel, and measurement starts when the arming
signal becomes True. For information about the settings in the Trigger Source/Time Base
Source/Arming Setting dialog box, see section 4.6, “Setting the Trigger Source/Time
Base Source/Arming” in the WE7000 User’s Manual (IM 707001-01E).
Waveform Display
You can display measured data as a waveform on the WE7231. When measurement is
started on WE7231’s operation panel, waveforms are automatically displayed by default
in the WE7000 Control Software’s waveform monitor.
Automatic Saving
Besides saving the waveform data from those displayed in the waveform monitor,
measured data can also be automatically saved. You can select to save the data to one
file or by specifying the number of data points you may save to multiple files.
File Conversion
Saved measurement data can be converted from ASCII data in CSV format (*.csv) or
physical values in 32-bit floating point format (*.wvf, conforming the IEEE754-1985
standard).
Measured Data Scaling
Set two arbitrary points from the measured values (VP1, VP2) and the physical value
corresponding to those measured values (SP1, SP2). The scale conversion equation
(y=mx+b) is determined based on these four values. The measured values are
converted to physical values according to this equation, and can be displayed in a
waveform or saved as measurement data.
