Sets or queries the source that will arm the acquisition system. You can specify
only one source at a time and it is shared by all acquired channels. Setting the
arm source to BUS configures the event detector to accept and arm on either the
*TRG or the VXIbus word serial <Trigger> command. The ECLTrg and TTLTrg
sources provide normal and inverted access to the standard ECLT and TTLT
signals on the VXI P2 bus. TTLTrg<n> arms when the TTLT line is low.
ITTLTrg<n> arms when the TTLT line is high. The ECLTrg<n> arms when the
ECLT line is high. IECLTrg<n> arms when the ECLT line is low. EXT arms
when the EXT input is a TTL low.

EXTernal is the front-panel BNC connector labeled Arm Input. Setting the arm
source to IMMediate bypasses event detection and immediately arms the
acquisition system.
