7-10 Triggering Model 6485 Picoammeter Instruction Manual
A) ABORt
If operation has been started by the INITiate command, ABORt will cancel all operations
and immediately return to the instrument to the idle state. If operation has been started by
READ? (or MEASure?), ABORt has no affect.
B) INITiate
1. After sending this command to take the instrument out of idle, the instrument will
perform one or more measurements and then return to idle. The FETCh? command
can then be used to read the last reading that was measured.
2. If INITiate is sent while the instrument is operating within the trigger model it will
not execute until the operation returns to the idle state.
3. One alternative to using INITiate is to use the READ? command. When READ? is
sent, the instrument is taken out of idle and all readings that are taken are returned
(See Section 13 for details on READ?).
C) ARM:SOURce <name>
With the TIMer control source selected, use the ARM:TIMer command to set the timer
interval.
D) ARM:DIRection <name>
The source bypass can only be used if the TLINk control source is selected.
E) ARM:ILINe <NRf> and ARM:OLINe <NRf>
Input trigger and output trigger cannot share the same trigger link line. Defaults set line 1
as the input and line 2 as the output.
F) :TRIGger:CLEar
When this action command is sent, any pending (latched) input triggers are cleared imme-
diately. When the picoammeter is being latched by another instrument, it may inadvert-
ently receive and latch input triggers that do not get executed. These pending triggers
could adversely affect subsequent operation.
When using external triggering, it is recommended that TRIGger:CLEar be sent after
sending the ABORt commend and at the beginning of a program before sending a initiate
command (See “INITiate” command.)
