Description
:LEVel?
Returns the level setting as a percentage of range.
:SIGNal
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.
:SLOPe POSitive|NEGative
Sets the signal slope that causes the event detector to be
satisfied if Soure is Internal. See also LEVel and COUPling.
Default = POSitive
:SOURce BUS|EXTernal|HOLD
|IMMediate|INTernal|LINE|MANu
al|SYNChronous|TIMer
Source of ARM signal
BUS = Receipt of *TRG or GET
EXTernal = Conforming rear panel trigger edge
HOLD = Arming cannot occur unless a
ARM:LAYer[1|2]:IMMediate or :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 = when the TRIG key is pushed
SYNChronous = Arms 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
:SOURce?
Returns the source setting
:TIMer
<nrf>
Sets the interval between TIMer events. Only active if Source =
timer. Default 2E-8 (20 ns).
:TIMer?
Returns the timer setting
