Note: DG1000Z can only identify files of which filenames consist of Chinese
characters, English letters, number and underscore. If other characters are used to
name the file or folder, the name might be displayed in the store and recall interface
abnormally.
File Type
Press Store  File Type to select the desired file type. The file types available
include State File, Arb File, Txt File, Csv File, Bmp File and All File.
1. State File
Store the instrument state in internal or external memory in “*.RSF” format. At
most 10 instrument states can be stored in internal memory.
The state file stored includes waveforms selected, frequency, amplitude, DC
offset, duty cycle, symmetry, phase and modulation, sweep, burst parameters
used of the two channels and counter parameters as well as utility parameters
and system parameters under the Utility menu.
2. Arb File
Store the user-defined arbitrary waveform in internal or external memory in
“*.RAF” format. At most 10 arbitrary files can be stored in internal memory.
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.
