E6706G Functionality Overview (continued)
Protocol logging
The wireless protocol advisor PC software included with the E6706G 1xEV-DO lab
application opens the ability to log and analyze protocol messages sent between the
test set and AT. Besides the ability to capture specific events or messages, the wireless
protocol advisor allows you to build customized filters to capture and analyze just the
information you want. Messages can be examined from the following protocol layers:
forward and reverse SLP-D, forward and reverse TAP, forward and reverse RLP, forward
and reverse PPP, and forward and reverse IP layer. Captured data, as well as any
customized triggers and filters, can be stored for future use. With this powerful protocol
logging capability, you can quickly track down issues in the protocol stack of your
1xEV-DO access terminal.
1xEV-DO test mode support
Receiver test without active call processing is supported in the E6706G 1xEV-DO lab ap-
plication through the IS-856 test mode. In test mode, the E6706G provides an accurate
1xEV-DO Release 0/A/B forward link signal that allows access terminals supporting test
mode operation to achieve time alignment. At this point, the AT can be directed to de-
modulate the forward traffic channel that is continuously transmitted by the test set. The
packet error rate of the AT can then be read from the AT using the AT’s test mode control
software. In addition, AT transmitter measurements such as channel power, Tx spurious
emissions, and time response of open loop power can be made in test mode.
Easy upgrade for existing CDMA-capable 8960 Series 10 test sets
Units that support the CDMA applications, like the E6702G, can easily be upgraded to
support 1xEV-DO test capabilities. Using the latest lab application features on existing
E5515C units may require purchasing hardware upgrade(s).
