Arbitrary Waveform Generator Memory

Internal Arbitrary Waveform Generator (AWG)

The Internal AWG has two types of memory - volatile memory and non-volatile memory. You can access signals stored in the AWG outside of the N7620B Pulse Building software.

Volatile Memory

Data stored in volatile memory cannot be recovered if it is overwritten, or if the power is cycled. This memory is partitioned as waveform memory (WFM1) and marker memory (MKR1).

WFM1 data is stored in the signal generator’s /user/bbg1/waveform/ directory.

MKR1 data is stored in the signal generator’s /user/bbg1/markers/ directory.

Non-volatile Memory

Data stored in non-volatile memory remains until you delete it. Unlike volatile memory, non-volatile memory is not partitioned; non-volatile waveform memory (NVWFM) and non-volatile marker memory (NVMKR) share the same space (along with bit, binary, and state directories).

NVWFM data is stored in the signal generator’s /user/waveform/ directory.

NVMKR data is stored in the signal generator’s /user/markers/ directory.

N603xA/M933xA or N824xA Arbitrary Waveform Generator

The N603xA/M933xA or N824xA AWGs only have volatile memory. You can only access stored signals using the N7620B Pulse Building software.

M8190A Arbitrary Waveform Generator

The M8190A AWGs only have volatile memory. You can only access stored signals using the N7620B Pulse Building software.

Volatile Memory

Data stored in volatile memory cannot be recovered if it is overwritten, or if the power is cycled.
