Memory Allocation
Volatile Memory
The signal generator allocates volatile memory in blocks of 1024 bytes. For example, a waveform file
with 60 samples (the minimum number of samples) has 300 bytes (5 bytes per sample
× 60 samples),
but the signal generator allocates 1024 bytes of memory. If a waveform is too large to fit into 1024
bytes, the signal generator allocates additional memory in multiples of 1024 bytes. For example, the
signal generator allocates 3072 bytes of memory for a waveform with 500 samples (2500 bytes).
3 x 1024 bytes = 3072 bytes of memory

The Agilent MXG uses an optional “USB media” to store non-volatile waveform data.
3 The Agilent MXG internal non-volatile memory is referred to as “internal storage”.
4 This NONVOLATILE directory shows the files with the same extensions as the USB media and is useful with ftp.
