Display Menu
The key provides access to the display menu, which enables auxiliary channels 3 and
4, controls the memory math functions, and leads to other menus associated with display
functions.
The analyzer has four available memory traces, one per channel. Memory traces are
channel dependent: channel 1 cannot access the channel 2 memory trace or vice versa.
Memory traces can be saved with
instrument
states: one memory trace can be saved per
channel per saved instrument state. Thirty one save/recall registers are available, so the total
number of memory traces that can be present is 128 including the four active for the current
instrument state. The memory data is stored as full precision, complex data. Memory traces
must be displayed in order to be saved with states.
Note You may not be able to store 31 instrument states if they include a large
amount of calibration data. calibration data contributes considerably to the
size of the instrument state file and therefore the available memory may be full
prior to all 31 registers.
