The user may change the default ho_typ=0 setting to either of the

following:

_ All (1) allows idle handoffs to all pilots being scanned regardless

of whether they are Neighbors or not.

_ None (2) suppresses Idle handoffs entirely. In this mode, the

Retriever Pilot Scanner acquires the best serving system, then

stays locked on this system regardless of whether or not an Idle

handoff is possible. This setting is useful for single-sector

coverage area logging without the complication of Idle handoffs

being present in the data. It is often referred to as “Sounder”

mode.

LOG_FMT

The log_fmt parameter controls how the Retriever Pilot Scanner

packages data for remote logging using the external Pilot Scanner

Interface Program. The following logging formats are supported:

_ Standard DM, for interfacing with AXESSTEL and other

vendors’ test gear, displays, and analysis tools

_ Dense-Pack, a special format which overcomes the link

limitations of the Standard format, allowing logging of every

search the Scanner sees

By default, the Retriever Pilot Scanner logs search scans in the

Dense-Pack format (Option 0). If necessary, Dense-Pack format can

be translated into DM format using the scan_trans command

The content of the Dense-Pack scanner log packet includes the time

stamp of the search, Rx power at the end of the search, LNA state

during the search, instantaneous E

c/Io of each of the four largest

energy peaks in the search window of each PN, and each peak’s

position (time delay).

Individual E

c values can be computed from this by adding Rx +

c/Io, where Rx represents an estimate of the total power Io.

Overall, the content of the binary log file using the Pilot Scanner

Interface Tool is the same as data collected by a standard

AXESSTEL Diagnostic Monitor. The only difference between
