8-6 Command Reference
:ARM :COUNt
8 <Numeric value>|MIN|MAX|INFinity *
No. of Measurements on each Bus arm
This count variable controls the upward exit of the “wait-for-bus-arm” state
(:ARM:STARt:LAY1). The counter loops the trigger subsystem downwards COUNt
number of times before it exits to the idle state.
This means that a COUNt No. of measurements can be done for each Bus arming
or INITiate.
L
The actual number of measurements made on each INIT is equal to:
(:ARM:START:COUNT)*(:TRIG:START:COUNT)
Parameters:
<Numeric value> is an integer between 1 and 2 147 483 647 (2
31
-1). (The integer 1 switches
the function OFF.)
MIN gives 1
MAX gives 2 147 483 647
* CNT-91 only: INFinity makes the arm loop continue indefinitely, or rather until other de-
vice-dependent parameters set limits. In practice, timestamping will probably collapse
after more than 100 days of non-aborted operation. The INFinity parameter is mainly
intended for continuous measurements, i.e. without defined end, where intermediate re-
sults can be fetched on the fly.
