Sets the scanned channel range, loop 
count, and timer length. All channels 
have a common measurement item.

In addition to the above Simple Scan 
settings, the advanced mode has custom 
settings for each channel, such as 
measurement item, range, and rate. 
Timer setting 
Sets the duration between each scan loop (Scan 
operation) or between each scanned channel (Step 
operation). 
Count setting 
Sets the number of scan operations (loop). 
Trigger setting  Internal

The GDM-8261 keeps triggering 
continuously until the scan reaches the 
end of the loop count. Then it goes into 
the idle mode.   
 External 
(Manual) 
The GDM-8261 stays in the idle mode by 
default. The trigger timing is manually 
controlled by the user from the front 
panel using the Trig key.   
Scan operation  Scan 
Measures all specified channel ranges 
(Channel MIN~MAX) for each trigger 
event. Timer settings (page 106) are 
applied between each scan for the whole 
channel range.
