Trace Memory Save/Recall
Setup memory
The HP 54620A/C has 16 separate setup memories that allow you to save the
current configuration of the instrument, including time base, threshold,
channel settings, measurement definitions, and labels (but not as 16
independent label lists). These memories are non-volatile. They are best used
for saving instrument configurations that you need later to verify the results
of a change, or need regularly for test and troubleshooting.
For example, suppose that you use the HP 54620A/C in field testing of a
system where ten separate tests are used. You can predefine the test
configurations and save them in setup memories 1-10. You might also record
the expected results as part of field test documentation. Then, a field service
engineer can take the instrument, connect it to a customer system, recall
each setup in turn, and compare the results to the expected results. This will
save test time and will increase accuracy, because preconfiguration
minimizes the chance for error.
