Saving Compare Images - HP 1652B Getting Started Manual

Note f#
When the trace mode is repetitive and Store exception to disk is on, the
following process takes place: data is acquired until the stop criteria is
met, data aquistion will stop, data in the acquisition memory will be
stored on the disk, and data acquisition will resume when the data is
stored. This process continues until the disk is full. The data is stored in
the same file name; however, the last three characters will
automatically be replaced with a numerical serial number. For
example, EXCEPTION will change to EXCEPT001 the second time
memory is stored.
-.
You may also specify a stop measurement based on time between the X
and 0 markers in the Compare or Difference Listing menus. This is
available only when Count is set to Time in the State Trace menu. If the
Stop Measurement is set to run until Compare Equal or Compare Not
Equal in the Compare or Difference Listings, the Stop Measurement
on time X to 0 will change to run until Compare Equal or Compare
Not Equal in the other state display menus (i.e. State Listing).

Saving
Compare
Images
When you save a logic analyzer configuration to a disk, the compare
images for both state analyzers are saved with it. The compare data is
compacted to conserve disk space. Likewise, when you load a
configuration from disk, valid compare data will also be loaded.
