SDS1000X-E SCPI commands problem
EDIT: as Veteran68 kindly suggests (see next post) I'll try official support channels and if they answer I'll report on forum.
Hi all, hi Tech Support
I am quite happy of my SDS 1104X-E (purchased 2022), very good value for money.
Recently I begin to use SCPI command (via pyVISA and Ethernet) and I’ve found some small problem or error in documentation…
problem #1 undocumented standard SCPI commands
Some important (IMHO) standard commands (present in previous version of Programming Guide) are not documented in last version, but they seems operational (not full tested, but something is surely working) and I’d like to know if these commands can be considered officially supported or not.
*ESR?
*STB?
*CLS
Problem #2 COMM_HEADER | CHDR
(long form does not work, but workaround is simple...)
>>> DSO.write("CHDR OFF")
short form works, but with OFF parameter does not always work as expected: “header is omitted from the response and units in numbers are suppressed”.
With PAVA? FREQ (don’t know if also other commands are affected) header is not entirely omitted (word FREQ is still present):
>>> DSO.query("C1:PAVA? FREQ")
'FREQ,5.001000E+01'
this makes more difficult to extract value as a number and in a different way than other commands, where header is entirely suppressed:
>>> DSO.query("CYMT?")
'5.00E+01'
Useful info:
