Using the Trigger Menu
Managing Memory
To set the memory length
The 1670G-series logic analyzer’s memory length can be adjusted. The
table on the following page shows the amount of memory available for
different modes of operation.
Typically you will want to use small amounts of memory at the
beginning of troubleshooting, when you are first looking for a problem,
and use deep memory when you are searching for the root cause.
Shallower memory provides faster acquisitions, but might not have
sufficient context. Deep memory provides more context, but takes
longer to fill, more time to display, and more time for you to analyze.
The Memory Length field allows you to configure the acquisition
memory to suit your needs.
1 In the Analyzer Trigger menu, select Acquisition Control.
The Acquisition Control menu pops up. If the acquisition mode is set to
Automatic, the menu contains two fields and an explanation. If
Acquisition has been customized, it has four or five fields and a picture
showing the amount of memory and where the trigger is currently
placed in memory.
2 Select the Memory Length field.
Use the knob to select the memory length. Memory size can be set in
powers of 2 from 4096 to the maximum. The table below shows the
maximum memory for various modes of operation.
