Title: Rigol DG1022Z, selfcreate waveform, not correctly reproduced?
Post by: kosmos on January 18, 2024, 01:12:07 pm

Hello, i try to write wave forms in the .txt format myself, but it only works in part.

Example 1:
16384 (SamplePoints)
16384 (max value)
1 (min value)
1
2
3
4
...
....
16383
16384
empty line

gives me a perfect sawtooth.

But if I try short examples, then the signal generator fills me always always fills the rest to 16384 with 1, so that my waveform are only short impulses.

Example2
8 (SamplePoints)
8 (max value)
1 (min value)
1
2
3
4
4
3
2
1
empty line

What is wrong here how can I prevent this if I want, for example, that these 8 sample points should be repeated directly without a long break 9-16384.

Arb - Arb Mode - SRate - Store - D: - 8_1.txt
csv or raf or Ultra Station+USB or LAN

thanks for the files. Only the .raf file works correctly, meaning that the signal repeats itself permanently. For the other signals, 8192-8 is inserted 8184 times 0, so that there is always a pause in between.

Picture 22+23 srate vs Freq. with big pause
Picture 24 o.k.
Picture 25 fail

Apply the configuration file for the generator 00000.rsf.
Then, open the text file 8_1.txt.
Further, according to the picture...
