Channel Scanner Setup
To customized the channel scan process, you can 
press  [Meas] > {Channel Scanner} > {Setup} to set the 
measurement interval and rule in the submenu.
The  Meas Interval is a value of time/distance during 
which the every two scan process is triggered. 
When it is set to off, the channel will be scanned 
with default settings. 
The  Interval Type is toggled between time and 
distance. When it is set to Time, the minimum 
interval time is 100 ms. When it is set to Distance, 
it allows you to measure the channel with the 
specific distance on the road test. The minimum 
interval distance is 1 meter. Please refer to the 
Figure 3- 31 on page 80 for the distance interval 
channel scan.
The  Measure Rule and Search Rule is toggled between 
Speed and Accuracy.
For each scan process, the analyzer will first 
search and find out the available channels 
according to the selected scan mode. Then, a 
precise measurement will perform to get the scan 
result.
The accuracy mode in measurement rule is set as 
default to get the precise measurement for the 
searching- out channels.
The speed mode will speed the measurement but 
reduce the measurement accuracy. It is set to 
default in search rule to search out the available 
channels approximately.
The  Top  Cyc le number is the searching times for 
each measurement. It allows you to measure the 
specific searching- out channels continuously.
NOTE
The option GPS is required to set the Interval Type to 
Distance. Press [System] > {More} > {GPS} > {GPS On}
