7.2 Recall
7.2.14.1 Load Segment to ARB Memory
Loads a single segment to ARB memory. Same as pressing the Recall button with a
single waveform selected.
Remote
Command
:SOURce:RADio:ARB:LOAD <string>
<string> - specifies the path name of the file to load from the HDD into ARB memory. May be a <full
path + filename>, or <“NVWFM” MSUS + colon + filename>
Example
:SOUR:RAD:ARB:LOAD "D:\NVARB\testwaveform.bin"
or
:SOUR:RAD:ARB:LOAD "NVWFM:testwaveform.bin"
Notes Because loading the file involves a delay of unpredictable length, this command should be followed by
*OPC?, which holds off subsequent commands until the loading operating is complete
If you specify a file over SCPI, but the file is not at the specified location, an error is generatedIf you try
to load a waveform file but the file contains less than 500 IQ samples, an error is generated
VXT models M9410A/11A/15A/16A and M9410E/11E/15E/16E:
If you try to load a waveform file but the file contains less than 1024 IQ samples, an error is generated
If you try to load a Signal Studio waveform *.wfm that contains invalid waveform header, an error is
generated
If the ARB is ON when you load a file to ARB memory or delete a file from ARB memory, the playing
waveform segment may not keep phase continuity during the ARB memory operation. The waveform is
replayed after the ARB operation is finished
ARB can be loaded into ARB memory even if required licenses are not present on the instrument. In this
case, a GUI-only warning message -800, “Operation complete; Loaded <filename> successfully, but no
license <required licenses> installed”. You can install required licenses according to <required
licenses> string to license it, or multi-pack license it
When in Sequence Analyzer Mode, and Include Source is Yes, an attempt to load a file to ARB memory
is rejected with an error. When Include Source is No, and if there is insufficient free ARB memory to load
the selected waveform, an error is generated
Remote
Command
:SOURce:RADio:ARB:LOAD:ALL <string>
<string> specifies the directory on the HDD to load the files into ARB memory from
Example
:SOUR:RAD:ARB:LOAD:ALL "D:\nvarb"
Notes Loads all the segment files within the currently selected directory into ARB memory. If a file of the same
name already exists within ARB memory, it is overwritten. If you wish to load two segments of the same
name, you must rename one of the segments before loading it into ARB memory. To rename a segment,
either use Windows File Explorer, or :MEMory:COPY
If you specify a directory over SCPI, but the directory does not exist, an error is generated
If the ARB is ON, and you then load or delete a file to ARB memory, the playing waveform segment may
not keep phase continuity during the ARB memory operation. The waveform is replayed after the ARB
operation is finished
When in Sequence Analyzer Mode, and Include Source is Yes, an attempt to load all files from a
