IEEE-488 Reference
3-153
These action commands are used to bypass the specified control source of the Trigger Model.
They are used when you do not wish to wait for the programmed event. Note from the Trigger
Model (Figure 3-13) that :arm:lay2:imm and :trig:imm also bypass the delay.
The instrument must be waiting for the appropriate event when this command is sent. Other-
wise, an error occurs and the command is ignored. When the command is sent, the bypass
occurs and operation continues on.
PRINT #1, "output 16; :trig:imm" ' Bypass measure control source
:COUNt <n>
:ARM[:SEQuence[1]][:LAYer[1]]:COUNt <n> Set arm layer count
:ARM[:SEQuence[1]]:LAYer2:COUNt <n> Set scan layer count
:TRIGger[:SEQuence[1]]:COUNt <n> Set measure layer count
<n> = 1 to 99999 Specify count
INF Sets count to infinite
DEFault Sets count to 1
MINimum Sets count to 1
MAXimum Sets count to 99999
:COUNt? Queries programmed count
:COUNt? DEFault Queries *RST default count
:COUNt? MINimum Queries lowest allowable count
:COUNt? MAXimum Queries largest allowable count
These commands are used to specify how many times operation loops around in the specified
layer of operation. For example, if the measure count is set to 10, operation continues to loop
around in the measure layer until 10 measurements are performed. After the 10th measurement,
operation proceeds back up to the scan layer.
PRINT #1, "output 16; :trig:coun 10; coun?" ' Set measure layer count
PRINT #1, "enter 16" ' Get response from 2002
:DELay <n>
:ARM[:SEQuence[1]]:LAYer2:DELay <n> Set scan layer delay
:TRIGger[:SEQuence[1]]:DELay <n> Set measure layer delay
<n> = 0 to 999999.999 Specify delay in seconds
DEFault 0 second delay
MINimum 0 second delay
MAXimum 999999.999 second delay
:DELay? Query the programmed delay
:DELay? DEFault Query the *RST default delay
:DELay? MINimum Query the lowest allowable delay
:DELay? MAXimum Query the largest allowable delay
These delay periods are used to delay operation in the specified layer. After the programmed
event occurs, the instrument waits until the delay period expires before proceeding on in the
Trigger Model. Note that the Arm Layer Arm Layer 1) does not use a delay.
PRINT #1, "output 16; :trig:del 1; del?" ' Set delay for measure layer
PRINT #1, "enter 16" ' Get response from 2002
