Example 1

FILENAME the waveform file name as it will appear in the signal generator’s waveform

memory catalog

#3 defines the number of decimal digits to follow in B. This variable is

represented by A in the sample command line.

240 denotes how many bytes of data are to follow. This variable is represented by

B in the sample command line.

(240 bytes of data) the binary waveform data order for each 2-byte sample is defined

as MSB (most significant byte) first and LSB (least significant byte) last.

The waveform must have at least 60 samples of data. Each sample (IQ data)

is represented by 4 bytes, 2 bytes for the I sample and 2 bytes for the Q

sample. In the example above the data, 240 bytes, represents 60 samples of

data.

Example 2

:MMEM:DATA "WFM1:file_name", #1912S407897

file_name the waveform file name as it will appear in the signal generator’s waveform

memory catalog.

#1 defines the number of decimal digits to follow in “B”.

9 denotes how many bytes of data are to follow.

12S407897 the ASCII representation of the data that is downloaded to the signal

generator. This variable is represented by C in the sample command line.
