Acquisition Criteria
These are the criteria according to which the data will be acquired. These include (among
other parameters), the measurement steps and the acquisition rate per step
(measurement point).
Duration of a measurement point = 2.5 milliseconds (ms).
Duration of a complete band = (Number of averaging points)*(Number of steps)*(0.0025).
Example:
( ( ) ( )) ( )
( )
( ) ( )
Maximum number of measured points is 25,000.If the span-to-step ratio exceeds this number, an
error message would be sent to the user.
NOTE:
The bandwidth filters (which effectively function as the

bandwidth) can be set to 50 KHz, 150 KHz and 300 KHz bands, depending on the carrier’s bandwidth.
