2.2.4 Saving Waveforms And Settings

In the oscilloscope mode there is generally not a known set of data in memory, except

perhaps as the result of a single shot trigger operation. The transient recorder mode handles the

recording to known data sets in memory somewhat like a sophisticated single shot trigger

operation. Therefore, saving of sample data to disk is not supported in oscilloscope mode.

However, there is always a waveform image on the display and saving this image to disk is

supported. Select the menu item Save Image in the File menu. A standard file dialog will ask

for a file name under which to store a bitmap image of the oscilloscope display. This bitmap can

be used in any document such as shown in Figure 2.5 below. When the image is saved to disk,

the Run/Stop control is set to

STOP. If the control was set to RUN, it is returned to RUN when the

file save is complete. This time will be very brief.

Generally, the oscilloscope mode is used to setup the TR122 instrument for transient

recording operations. Some setting can not even be changed once transient recorder mode is

entered. For this reason, if settings are to be saved to disk to preserve a given setup, the

oscilloscope mode would be the right place to do it. The menu items Save Settings and Load

Settings are available in the File menu in the oscilloscope mode. The Save Settings item will

prompt for a file name under which to save the current settings of the user controls. When the

TR122 software is started, default settings are always installed. Stored settings can be retrieved

using the Load Settings menu item.
