Front Panel Operation
2-81
NOTE
The front panel TRIG key is active when EX-
TERNAL, GPIB or TRIGLINK is selected.
GPIB: With this selection, bus triggers control the arm source.
Operation passes immediately into the scan layer when a bus
trigger (GET or *TRG) is received by the Model 6517A. See
Section 3 for detailed information on bus triggers.
NOTE
The front panel TRIG key (see MANU-
AL) is active with bus triggering selected.
Pressing the TRIG key passes operation
into the scan layer.
TRIGLINK: With this selection, the arm source is controlled
by the Trigger Link of the Model 6517A. Trigger Link is an
enhanced trigger system that uses up to six lines to direct
trigger pulses to and from other instruments. Operation pass-
es into the scan layer when the Model 6517A receives a trig-
ger over the Trigger Link. See paragraph 2.15.5 for details on
using the Trigger Link.
NOTE
The front panel TRIG key (see MANU-
AL) is active with the Trigger Link select-
ed. Pressing the TRIG key passes
operation into the scan layer.
After selecting TRIGLINK, you will be prompted to select
an input line and then an output line. Note that you cannot
use the same trigger line for both input and output.
RT-Clock: With this selection, the arm source is controlled by
the real-time clock. When the programmed time and data oc-
curs, the Model 6517A passes operation into the scan layer.
• SET-TIME — Use this selection to set the time (hour,
minute and second) for the arm event. Set the time using
the 12-hour format if “AM” or “PM” is displayed (see
CLOCK in paragraph 2.19.7). Otherwise, set the time
using the 24-hour format.
• SET-DATE — Use this selection to set the date (month,
day and year) for the arm event.
