TRACKING [GRTMM]
The number of scans of graph data between resetting the tracked min and max when in
graph mode. Select SINGLE or INFINITE.
REF LINE [GRFS]
Causes a dotted horizontal line to be drawn at the reference point on the graph screen;
normally OFF.
PRE TRG% [GRPTP]
Percentage of the screen that displays pretrigger information at the best resolution
available. The display shows an ‘x’ marking the trigger point on the time axis.
Data before the actual trigger event is not available. The trigger reference point (x)
indicates the active trigger point after the DELAY setting in the System > Profile
menu. Providing sufficient delay has been set, the PRE TRG% can be used to move this
reference to anywhere on the screen. The amount of valid data displayed before the
trigger reference point is dependent on the System > Profile > DELAY setting.
Secure [SECURE]
Normally OFF. When the system is powered on the ML243xA returns to the state it was in
when it was powered off. This includes all of the offset tables, calibration adjust values, etc.
If Secure is set to Clear memory, non-volatile memory is disabled and all stored values are
reset to the factory defaults when the system is powered on. As long as this selection is set to
Clear memory, the system will load the presets (see Appendix A, Section A-3) every time it is
turned on.
Identity [*IDN, OI]
This selection will display the installed firmware version, the instrument serial number, and
the instrument type (model number).
Note
These options allow either the min/max of each sweep to be displayed (single) or
the conventional method for tracking variation of levels over an extended period of
time (infinite).
