Command
:ARM:SENS
Long

Form
Set & Query
Parameter
EDGE | LEVel
*RST value
EDGE
Description
Use this command to select Triggered or Gated mode by choosing
whether the instrument arms on the edge(s) or level of the arming signal.
When sensing edges, the instrument triggers when the arming signal
crosses the selected threshold level (
:ARM:LEV
) in the selected direction
(
:ARM:SLOP
). This corresponds to the Triggered mode selected on the
Mode/Trigger screen when using the front panel.
When sensing levels, the instrument triggers as long as the arming signal
is above (
:ARM:SLOP POS
), or below (
:ARM:SLOP NEG
) the selected
threshold level (
:ARM:LEV
). This corresponds to the Gated mode
selected on the
M
ODE
/T

SCREEN
when using the front panel.
Command
:ARM:SLOP
Long
:ARM[:SEQuence[1]|STARt][:LAYer]:SLOPe
Form
Set & Query
Parameter
POSitive | NEGative | EITHer
*RST value
POS
Description
Use this command to select the trigger slope for the arming signal when
triggering on edges. Use
EITHer
to trigger on both the positive and
negative edges of the arming signal. This allows you to trigger at twice
the frequency of the arming signal.
If you are arming on levels, use this command to select whether the
instrument triggers during the positive or negative cycle of the arming
signal.
