6.1 RF Source
Query the waveform on the hard disk by MSUS:
:MMEM:HEAD:ID? "NVWFM:test.wfm"
Notes The queried waveform file can be in ARB memory, or on hard disk. If want to query ARB in ARB memory,
then give out the file name directly. If want to query ARB on the hard disk, then absolute file path or
MSUS should be given along with the file name. The valid MSUS is NVWFM, which is mapped to
D:\NVARB on the hard disk
If the file cannot be found in ARB memory or on hard disk, an error is generated and value -1 is returned
Query Selected Waveform Header info (Remote Query Only)
Returns a listing of the current selected ARB header info. If no ARB selected, then
empty string is returned.

Command
:SOURce:RADio:ARB:HEADer:INFormation?
Example
:SOUR:RAD:ARB:HEAD:INF?
Notes After each colon of field title string, related header info string is appended
The field title string in “Range” part cannot change, for Sequence Studio needs to accurately match
those string character to know which header info field it is
