Basic Digital Operation (Option 651/652/654)Storing, Loading, and Playing a Waveform SegmentStoring, Loading, and Playing a Waveform SegmentNOTEThe MXG’s ARB Waveform File Cache is limited to 128 files. Consequently, once the 128 filecache limit has been reached, the waveform switching speed will be much slower foradditional files loaded into the volatile waveform memory (BBG).Before using this information, you should be familiar with the signal generator’s file menus. If youare not, refer to “Working with Files” on page 63 and familiarize yourself with that information.See also: “Waveform Sequences” on page 145.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 8-2Waveform Segment Softkeyspage 155Note: When a sequence is selected, this key namechanges to Show Waveform Sequence Contents.These keys change to indicate the default media.For information on selecting the default media,see page 74.For details on each key, use key helpas described on page 42.Use the arrow keys or knob tohighlight a letter or character.Loading 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.NOTEEach time the instrument powers up, two factory–supplied segments are automaticallycreated in BBG media: RAMP_TEST_WFM and SINE_TEST_WFM.There are additional sample waveforms that are available in the internal storage and thatcan be loaded into memory. Refer to www.agilent.com and search on “Factory DefaultN5182A” and “waveforms”.1.
