Hi Teles.
Thank you very much.  It is ok now by adding "type+class ".

The command for MSO 4 series doesn't work correctly for MDO 34, It seems only below type could be selected.
Syntax TRIGger:A:TYPe {EDGe|LOGIc|PULSe|BUS|VIDeo}

But below commmand is working fine if we select the timeout type manually.
TRIGger:A:TIMEOut:POLarity
TRIGger:A:TIMEOut:SOUrce
