After executing the TARM SGL command, one reading is taken
per sample event until the specified number of readings are
Any completed. The trigger arm event then becomes HOLD. When
using the SYN sample event, the input buffer must be enabled or
you must suppress cr lf when sending the TARM SGL command.
After executing the TARM SGL command followed by a negative
edge transition on the Ext Trig input, one reading is taken per
sample event, until the specified number of readings are
completed. The trigger arm, event then becomes HOLD.

After executing the TARM SGL command followed by the
occurrence of the LEVEL event,
sample event until the specified number of readings are
completed. The trigger arm event then becomes HOLD.

After executing the TARM SGL command followed by the power
line voltage crossing zero volts, one reading is taken per sample
event until the specified number of readings are completed. The
trigger arm event then becomes HOLD.
