PC Card Evaluation
This chapter describes several software programs supplied
with the kit. It also details some diagnostic test points that
may be accessed on the card.
Using the PRISM Test Utility (PTU) Software
The PTU permits continuous operation of the transmitter. It is
therefore convenient for performing RF measurements such
as Transmitter Power. It also provides a handy method of
changing channels within the ISM band, Use of the PRISM
Transmitter Test Utility is basically self explanatory. An icon
was automatically created on the desktop when the PTU
installation was performed. It may be run by double-clicking
on this icon.
Using the LANEVAL Software
LANEVAL provides a convenient method of analyzing
Packet Error Rate (PER) and Receiver Sensitivity. An icon
for starting LANEVAL was automatically placed on the
desktop when the PTU installation was performed. In order
for LANEVAL to form a successful link, the same packet
parameters (e.g., Packet Length, Packet Pad Words, etc.)
most be programmed at each end of the link.
LANEVAL runs in conjunction with the NDC Driver. The
Driver permits selection of Data Rate and Channel. It is
normally run in the Pseudo IBSS mode as this provides a
simple wireless Ad Hoc link between two computers. The
NDC Driver may be easily accessed by double-clicking on its
icon (looks like a computer with an antenna on top) located
in the System Tray area on the desktop.
