To set the external trigger signal as the arm source:
ARM:SOUR EXT
The trigger counter controls how many trigger events will be allowed to
start a measurement scan. When the number of trigger events set with the
command is reached, the module returns to the trigger idle
TRIGger:COUNt
state (needs to be
INITiated
the trigger idle state after each scan). If
the trigger counter is disabled and the module will accept an unlimited
number of trigger events.
To set the trigger counter to 100:
TRIG:COUN 100
The format of the readings stored in the FIFO buffer and CVT never
changes. They are always stored as IEEE 32-bit floating point numbers.
The format
FORMat:DATA <
whether and how the readings will be converted as they are transferred from
the CVT and FIFO.

The <format>[,<length>] parameters can specify:
PACKED
REAL,32
REAL
REAL,64
ASCii,7
ASCii
To specify that readings are to remain in IEEE 32-bit floating point format
for fastest transfer rate:
FORM:DATA REAL,32
To specify that readings are to be converted to 7-bit ASCII and returned as a
15 character per reading comma separated list:
FORM:DATA ASC,7
or
FORM:DATA ASC
again). The default trigger count is 1 (returns to
TRIGger:COUNt
Can trigger 100 times after a
single INITiate command.
