Hi guys.
Looks like there is a bug (yet another one, right) in the Rigol DS1000D firmware. My scope is DS1052D, revision 00.02.06.
It turned out that sampling mode (Equ-Time vs Real-time) can be queried via SCPI, but unlike other acquisition parameters, it cannot be changed.
Since I am making a tool for automated signal analysis, I would like to know whether this bug is present in other revisions and product versions (100 MHz version and/or version without Logic Analyzer).
Please, try to reproduce and tell if it worked with your scope (specify your model, revision).
:ACQUIRE:MODE? <----- gives REAL_TIME
:ACQUIRE:MODE EQUAL_TIME
:ACQUIRE:MODE? <------ still gives REAL_TIME
If I manually change sampling mode via menus,
:ACQUIRE:MODE? <----- gives EQUAL_TIME
:ACQUIRE:MODE REAL_TIME
:ACQUIRE:MODE? <------ still gives EQUAL_TIME
