In arbitrary waveform file, the voltage values corresponding to each waveform
point are stored in binary data format. In sample rate edit mode, if the points
is set to Sa, the arbitrary waveform file only contains Sa points of which the
voltage all are user-set values. In period edit mode, if the points is set to Sa,
the voltage of the first Sa points are user-set values and the voltage from the
(Sa+1)th point to the 8192th point are low level. The voltage value of each
point takes 2 bytes (16 bits). The lower 14 bits are used to represent voltage
and the higher 2 bits are unused. Therefore the format of binary data is from
0x0000 to 0x3FFF. Wherein, 0x0000 corresponds to the low level of the
arbitrary waveform and 0x3FFF corresponds to the high level of the arbitrary
waveform.
The stored arbitrary waveforms can be read by each model of DG1000Z series.
Besides, the arbitrary waveforms stored in USB storage device can be opened
and edited by data editing tools (such as WinHex or UltraEdit etc.) via
computer.
3. Txt File
Read the Txt files stored in external memory. The data of each line (can not
be longer than 64 characters) is considered as an arbitrary waveform point
and the data of all lines in the file are normalized to form an arbitrary
waveform. The arbitrary waveform is stored in volatile memory. The
instrument will enter the Arb interface automatically when the "Read"
operation is finished.
