6 REMOTE INTERFACE
APS-1102A 6-57
6.7 Programming example
Refer to "Remote Control Programming Example" included in the attached CD-ROM.
6.8 Programming Precautions
a) Arbitrary waveform data
Arbitrary waveform data comprises a block of binary data. The preceding ASCII program message
command field and the binary data block arbitrary waveform data should be transferred at the same
time. Always transfer arbitrary waveform data in 4096-word (8192-byte) batches. If the data count is
insufficient, an error may occur, in which case the correct waveforms cannot be output.
b) Caution concerning commands issued via the USB interface
When transferring commands, LF (0AH) must be appended at the end of the transmitted message
string as the program message terminator. If a command is sent without appending this LF, operation
will be incorrect.
