To Set a Scan Interval
You can set the instrument’s internal timer to automatically scan at a specific 
interval (e.g., start a new scan sweep every 10 seconds) or when an external TTL 
trigger pulse is received. You can configure the instrument to scan continuously or 
to stop after sweeping through the scan list a specified number of times. 
1 Select the interval scan mode.
For this example, select the Interval Scan mode which allows you to set the 
time from the start of one scan sweep to the start of the next scan sweep. Set 
the interval to any value between 0 and 99 hours
2 Select the scan count. 
You can specify the number of times that the instrument will sweep through 
the scan list (the default is continuous). When the specified number of sweeps 
have occurred, the scan stops. Set the scan count to any number between 1 
and 50,000 scans (or continuous).
