\w Welcome to LanExpert Help. Help information is provided for each screen to assist in correctly setting
up the LanExpert and understanding the test data. \n
\y ANALYZE NETWORK \n
\w Network tests include Link, Protocols, Vitals, Problems, Top Talkers, Devices, Ping, Trace Route, Generate

\y SELECT PROFILES \n
\w A Profile is a user-defined setup configuration. Profiles allow the user to pre-store setup parameters
that are typical for the network(s) to be tested. There are forty-nine user defined profiles and one factory 
default profile. The default settings cannot be changed. Factory default parameters are set for a DHCP network. 
For devices/networks using static IP addresses create a new profile.
ENDPAGETEXT
STARTPAGETEXT=3,3
\y PROFILE NAME \n
\w Input a profile name using the display keyboard to identify each profile. Press Enter to go back to the SELECT
PROFILE screen. 
ENDPAGETEXT
STARTPAGETEXT=3,4

modes must have both LanExpert ports connected to one device or between two network devices. \n
\y LINK AS \n
\w Link can be conducted in an Auto wire pair select mode or forced to a single mode simulating a network device (LAN)
or a computer (NIC). Auto MDI-X will link at the first compatible mode, which provides faster testing. Auto+Detect will
test for all modes available before linking and displays this configuration for the Link Partner. \n
\y SPEED/DUPLEX \n

ENDPAGETEXT
STARTPAGETEXT=3,132
\y Thorughput \n
\w Throughput defines the maximum number of frames per second that can be transmitted without any error. This test measures 
the rate-limiting capability of an Ethernet switch. The test starts at a maximum frame rate and then compares the number of
transmitted and received frames. If frame loss
occurs, the transmission rate is dropped and the test is restarted until the rate at which there is no frame loss is found.
ENDPAGETEXT
STARTPAGETEXT=3,133
\y Latency \n
\w Latency measures the time required for a frame to travel from the originating device through the network to the destination
device. This test can also be configured to measure the round-trip time, the time for a frame to travel from the originating 
device to the destination device and then back.
Latency uses the throughput test results to ensure the frames are transmitted without being discarded. This measures the worst
case conditions. Next, all transmitted frame are tagged with a time-stamp and when it they are received back at the test 
instrument, the latency is measured.
ENDPAGETEXT
STARTPAGETEXT=3,134
\y Frame Loss \n
\w Frame loss measures the networks response in overload conditions. The LanExpert sends traffic at maximum line rate and 
then measures if the network dropped any frames. If so, the values are
recorded, and the test will restart at a slower rate. This test is repeated until there is no frame loss. The results are 
presented as a percentage of frames that were dropped.
ENDPAGETEXT
STARTPAGETEXT=3,135
\y Back-to-Back \n
\w Back-to-back assesses the buffering capability of a switch. It measures the maximum number of frames received at full 
line rate before a frame is lost. A burst of back-to-back frames is transmitted across the network. If a frame is dropped, 
the burst length is shortened and resent. If there are no errors detected, the burst length will be increased.
ENDPAGETEXT
STARTPAGETEXT=3,136
\y Stress Test Storage \n
\w Stress test can be saved internally in the LanExpert or Externally onto a USB flashdrive. The external filename has an
