and sending a preset specified signal to the first process so that the first process obtains the information file according to the preset specified signal.
8. A non-transitory computer storage medium storing computer executable instructions executable by a processor to implement:
under the condition that an arbitrary waveform generator is in an un-updated state, acquiring first process information from a state file corresponding to the arbitrary waveform generator;
when a first process is in an operation state, creating an information file and sending the information file to the first process; the information file at least comprises a case number and a slot number corresponding to the arbitrary waveform generator;
the waveform configuration of the arbitrary waveform generator is cleared through the first process, and the state of the arbitrary waveform generator is changed into a state to be updated;
re-writing second process information in the state file, changing the state of the arbitrary waveform generator into an updated state, and loading waveforms corresponding to the second process to the arbitrary waveform generator;
before the information file is sent to the first process, the method further comprises:
acquiring an established information file corresponding to the arbitrary waveform generator;
carrying out clearing treatment on the information in the created information file;
writing the case number and the slot number currently corresponding to the arbitrary waveform generator into the information file;
the creating an information file and sending the information file to the first process specifically includes:
creating an information file corresponding to the arbitrary waveform generator;
writing the machine box number and the slot number corresponding to the arbitrary waveform generator into the information file;
and sending a preset specified signal to the first process so that the first process obtains the information file according to the preset specified signal.
