Different scanning agents run on different schedules, currently the following applies;
nmap ping and subsequent arp - every 10 minutes
reverse DNS - every 30 minutes
snmp scanner - every 30 minutes
There is also already a future development item to add a "scanners control panel" to control scanners on a per address range basis.
The overall polling period can be set in the diagnostics section.
