Record data and event information to a file
Syntax
record(obj)
record(obj,'switch')
Arguments
obj |
An instrument object. |
'switch' |
Switch recording capabilities on or off. |
Description
record(obj)
toggles the recording state for obj.
record(obj,' initiates or terminates recording for switch')
obj. switch can be on or off. If switch is on, recording is initiated. If switch is off, recording is terminated.
Remarks
Before you can record information to disk, obj must be connected to the instrument with the fopen function. A connected instrument object has a Status property value of open. An error is returned if you attempt to record information while obj is not connected to the instrument. Each instrument object must record information to a separate file. Recording is automatically terminated when obj is disconnected from the instrument with fclose.
The RecordName and RecordMode properties are read-only while obj is recording, and must be configured before using record.
For a detailed description of the record file format and the properties associated with recording data and event information to a file, refer to Debugging: Recording Information to Disk.
Example
This example creates the GPIB object g, connects g to the instrument, and configures g to record detailed information to the disk file MyGPIBFile.txt.
g = gpib('ni',0,1);
fopen(g)
g.RecordDetail = 'verbose';
g.RecordName = 'MyGPIBFile.txt';
Initiate recording, write the *IDN? command to the instrument, and read back the identification information.
record(g,'on') fprintf(g,'*IDN?') out = fscanf(g);
Terminate recording and disconnect g from the instrument.
record(g,'off') fclose(g)
