Reference Multimeter and 8 ½ Digit Multimeter
Description
Modifies event detection behaviour. If the system is waiting
for an event in this layer this one-time command bypasses
event detection. Otherwise, the command is ignored and
error -221 issued.
Sets the signal slope that causes the event detector to be
satisfied if Source is Internal. See also LEVel and COUPling.
Default = POSitive
Source of ARM signal
BUS = Receipt of *TRG or GET
EXTernal = Conforming rear panel trigger edge
HOLD = Arming cannot occur unless a TRIGger:IMMediate
or TRIGger:SIGnal command is received
IMMediate = The process does not stop at the event detector
in this layer
INTernal = Trigger from the signal being measured at the
Level on the Slope set by the ARM:LAYer[1|2]:LEVel <nrf>
and ARM:LAYer[1|2]:SLOPe POS|NEG commands. See also
ARM:LAYer[1|2]:COUPling AC|DC
LINE = trigger derived from the mains input. Triggers occur at
the line frequency rate or multiples of that rate if the trigger
system cycle time exceeds the line frequency.
MANual = the TRIG key is pushed
SYNChronous = Initiates an acquisition when the
multimeter's output buffer is empty, and the controller
requests data.
TIMer = at the interval set by ARM:LAYer[1|2]: TIMer <nrf>.
On the first of ARM:LAYer[1|2]:COUNt <nrf> passes, arming
is immediate, subsequent arms occur at TIMer intervals
Returns the source setting
Sets the interval between TIMer events. Only active if Source
= timer. Default 2E-8 (20 ns).
Returns the timer setting
