Creating and Downloading Waveform Files
Waveform Memory
For more information on default cluster sizes for FAT file structures, refer to Table 5- 3 on page 202
and to http://support.microsoft.com/.
Non-Volatile Memory (ESG/PSG)
The ESG/PSG signal generators allocate non- volatile memory in blocks of 512 bytes. For files less
than or equal to 512 bytes, the file uses only one block of memory. For files larger than 512 bytes,
the signal generator allocates additional memory in multiples of 512 byte blocks. For example, a file
that has 21,538 bytes consumes 43 memory blocks (22,016 bytes).
Memory Size
The amount of available memory, volatile and non- volatile, varies by option and the size of the other
files that share the memory. When we refer to waveform files, we state the memory size in samples
(one sample equals five bytes). The ESG and PSG baseband generator (BBG) options (001, 002, 601,
or 602) and the Agilent MXG baseband generator (BBG) Option (651, 652, and 654) contain the
waveform playback memory. Refer to
Tables 5- 4 on page 203 through Table 5- 6 on page 204 for the
maximum available memory.
