Bases: IntFlag

Enum element for SRQ mask bit decoding

property SRQ_mask

Return current SRQ mask, this property can be set,

bit assignment for SRQ:

Bit (dec)	Description
1	SRQ when invalid program
2	SRQ when trigger is ignored
4	SRQ when data ready

check_errors()

As this instrument does not have a error indication bit, this function always returns an empty list.
