Preset Limits
Time preset can be
Seconds
,
Minutes
,
Hours
, or
Days
. Preset time can be in effect
while other preset conditions (i.e. Comp Preset) are active. Fractional values for the
respective unit range are accepted. Effective preset time can range from 0.1s to
42,948,000s.
Comp Preset
Computational preset can be enabled for PHA, MSS, and DLFC. Selecting
None
disables Comp Preset.
If
Integral
is selected then the
Comp Limit
value represents the integral (or sum of all
counts) within the specified channels’ range for Input 1 that will terminate
acquisition.
The comp window is specified in channel numbers (
Start and End
) whose values are
based on the current Input Size setting.
Latch
Available for LIST and TLIST modes. For LIST selects the
Fast Discriminator
or
Peak Detect
as the latch time when the energy event is sampled; for TLIST, selects
the source for the timestamp of the energy event,
Fast Discriminator
or
Peak Detect
.
Timebase
Available for LIST and TLIST. Selects the resolution of the list mode clock which is
used for the sampling rate and, for TLIST, selects the source for the timestamp of the
energy event. Can be set to 100 nSec or 1.0 µSec.
Clock Source
Available for LIST and TLIST. Clock source for time tagging List data.
Internal
selects the Lynx built-in 1 MHz clock.
External
selects an external source supplied
through the External Sync input. This field is available when the External
Synchronization status is set to “Independent”.
