Description siloam 2018-06-15 16:34:19 CEST 
When using the rigol-ds driver over an Ethernet connection and selecting multiple channels, data is returned only for CH1. Only one trace displayed in PulseView. Using sigrok-cli to obtain a frame of data from two channels (CH1, CH2) seemed to return data only for CH1.

The problem does not occur when using a USB connection. In this case, data for both channels is returned and two traces are visible in PulseView.

The command used and the response (with -l 5) follow below:

$ sigrok-cli -d rigol-ds:conn=tcp-raw/10.210.210.78/5555 -l 5 --frames 1 -O analog --channels CH1,CH2

Hardware used was a Rigol DS1054Z oscilloscope. A recent report on sigrok-devel suggests that the issue may also be occuring with a Rigol MSO1104Z instrument.

Comment 3 Uwe Hermann 2018-06-15 18:51:22 CEST 
This is a duplicate of the (already fixed) #1018, marking as such.

The bug reporter has confirmed on IRC that the latest git libsigrok does not have the bug indeed.
