:TIMer?
Query programmed timer interval
:TIMer? DEFault
Query *RST default timer interval
:TIMer? MINimum
Query lowest allowable timer interval
:TIMer? MAXimum
Query largest allowable timer interval
These commands are used to set the interval for the scan layer and measure layer timers. Note
that the timer is in effect only if the timer is the selected control source. Also, note that the arm
layer (Arm Layer 1) does not use a timer.
PRINT #1, "output 16; :trig:tim .25; tim?"
' Set timer for Measure Layer
PRINT #1, "enter 16"
' Get response from 2002
:SIGNal
:ARM[:SEQuence[1]][:LAYer[1]]:SIGNal
Bypass arm control source
:ARM[:SEQuence[1]]:LAYer2:SIGNal
Bypass scan control source
:TRIGger[:SEQuence[1]]:SIGNal
Bypass measure control source
These action commands are used to bypass the specified control source and also when you do
not wish to wait for the programmed event. Keep in mind that the instrument must be waiting
for the appropriate event when the command is sent. Otherwise, an error occurs and this com-
mand is ignored.
PRINT #1, "output 16; :trig:sign"
' Bypass measure control source
TCONfigure commands
:PROTocol <name>
:TRIGger[:SEQuence[1]]:TCONfigure:PROTocol <name>
Specify Trigger Link protocol
<name> = ASYNchronous
Asynchronous Trigger Link mode
SSYNchronous
Semi-synchronous Trigger Link mode
:PROTocol?
Query programmed Trigger Link protocol
This command is used to select the protocol for the measure layer Trigger Link. With ASYN-
chronous selected, separate trigger lines are used for input and output triggers. With SSYNchro-
nous selected, a single trigger line is used for both input and output triggers.
Note that the arm and scan layers only use the asynchronous Trigger Link mode and therefore,
do not have to be selected.
PRINT #1, "output 16; :trig:tcon:prot ssyn; prot?"
' Select semi-sync proto-
col
PRINT #1, "enter 16"
' Get response from 2002
:DIRection <name>
