Keysight EXG and MXG X-Series Signal Generators User’s Guide 189Basic Digital Operation (Option 653/655/656/657)Storing, Loading, and Playing a Waveform SegmentStoring, Loading, and Playing a Waveform SegmentBefore using this information, you should be familiar with the signal generator’s file menus. If youare not, refer to “Working with Files” on page 56 and familiarize yourself with that information.See also: “Waveform Sequences” on page 192.The signal generator has two types of waveform media: non–volatile (internal or USB), and volatile(BBG). BBG media is also called “working” media, because before you can play, edit, or include awaveform file in a sequence, the waveform file must be loaded into BBG media.Figure 9-2 Waveform Segment SoftkeysLoading a Waveform Segment into BBG MediaWaveforms must reside in BBG media before they can be played, edited, or included in a sequence.Cycling power or rebooting the signal generator deletes the files in BBG media.1. Press Mode > Dual ARB > Select Waveform > Waveform Segments.2. Press Load Store to highlight Load, then use the arrow keys to highlight the desired waveformsegment.he MXG/EXG’s ARB Waveform File Cache is limited to 128 files.Consequently, once the 128 file cache limit has been reached, thewaveform switching speed will be much slower for additional files loadedinto the volatile waveform memory (BBG).Each time the instrument powers up, two factory–supplied segments areautomatically created in BBG media: RAMP_TEST_WFM andSINE_TEST_WFM.page 203For details on each key, use key helpas described on page 40.Note: When a sequence is selected, this key namechanges to Show Waveform Sequence Contents.Use the arrow keys or knob tohighlight a letter or character.These keys change to indicate the default media.For information on selecting the default media,see page 67.
