Source
When in Sequence Analyzer mode, and Include Source is Yes, an attempt to load a file to ARB
memory will be rejected with an error.
When Include Source is Noand if there is insufficient free ARB memory to load the selected
waveform, an error is generated. .
If you specify a file over SCPI, but the file is not at the specified location, an error is generated.
If you try to load a waveform file but the file contains less than 500 IQ sampes, an error is generated.
If you try to load a Signal Studio waveform “*.wfm” which contains invalid waveform header, an error
is generated.
If the ARB is ON when you load afile 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
will be replayed after the ARB operation is finished.
ARB can be loaded into ARB memory even required licenses do 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”. User can install required licenses according to <required
licenses> string to license it, or multi-pack license it.
Initial S/W Revision A.05.00
Load All To ARB Memory
Allows you to load 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, you can either use Windows File Explorer, or the :MEMory:COPY command.
NOTE: When a waveform file is loaded to ARB memory, burst timing adjustments are made automatically,
based on whether or not a Multiport Adapter is connected to the test set and powered on. If the
connection/power status of the Multiport Adapter is changed after a waveform file has been loaded, it
needs to be loaded again.
Key Path
Source, Modulation Setup, ARB, Select Waveform, Segments on Hard Disk
Remote Command :SOURce:RADio:ARB:LOAD:ALL <string>
Example :SOUR:RAD:ARB:LOAD:ALL “D: varb”
Notes <string> - specifies the directory on the HDD to load the files into ARB memory from.
When in Sequence Analyzer mode, and Include Source is Yes, an attempt to load all files from a
directory to ARB memory is rejected with an error.
When Include Source is No and there is insufficient free ARB memory to load all the waveforms,
when the ARB memory is full, the copy ceases, and an error is generated.
If you specify a directory over SCPI, but the directory does not exist, an error is generated.
If the ARB is ON, a user then loads or deletes file to ARB memory, the playing waveform segment
may not keep phase continuity during the ARB memory operation. The waveform will be replayed
after the ARB operation is finished.
