Thank you Martin for answering.. compiling everything, my pc detects the DSO.

sigrok-cli -d rigol-ds:conn=tcp-raw/192.168.1.21/5555 -l 5 --scan

sr: libsigrok loglevel set to 5.
sr: backend: Sanity-checking all drivers.
sr: backend: Sanity-checking all input modules.
sr: backend: Sanity-checking all output modules.
sr: backend: Sanity-checking all transform modules.
srd: libsigrokdecode loglevel set to 5.
sr: hwdriver: Initializing driver 'rigol-ds'.
sr: hwdriver: sr_config_list(): key 40000 (scan_options) sdi (nil) cg NULL ->

sr: scpi: Opening RAW TCP device tcp-raw/192.168.1.21/5555.
sr: scpi_tcp: Successfully sent SCPI command: '*IDN?'.
sr: scpi: Got response: 'RIGOL

sr: scpi: Got IDN string: 'RIGOL 
TECHNOLOGIES,DS1104Z,DS1ZB163351133,00.04.01.SP2'
sr: hwdriver: Scan of 'rigol-ds' found 1 devices.
The following devices were found:
rigol-ds - Rigol DS1104Z 00.04.01.SP2 with 4 channels: CH1 CH2 CH3 CH4



However if I try this command:

sigrok-cli -d rigol-ds:conn=tcp-raw/192.168.1.21/5555 --frames 1 -O analog
FRAME-BEGIN
sr: rigol-ds: Received invalid data block header 'co'.
sr: rigol-ds: Read error, aborting capture.
FRAME-END


What does it mean?


Other commands I tried:

sigrok-cli -d rigol-ds:conn=tcp-raw/192.168.1.21/5555 --continuous -O analog
This device does not support continuous sampling.



Or:

sigrok-cli -d rigol-ds:conn=tcp-raw/192.168.1.21/5555 --time 3000
This device does not support time limits.


Or:
sigrok-cli -d rigol-ds:conn=tcp-raw/192.168.1.21/5555 --samples 100 -O analog
Failed to configure sample limit.

It's supported in the current git master version. It wasn't supported
yet at the time of the last release,  which is what you have as packaged
by Ubuntu.

If you want to use this scope with sigrok, you should uninstall the
Ubuntu packages and build the whole stack (libsigrok, libsigrokdecode
and sigrok-cli or pulseview) from git.

No, this will make no difference.
