Network Testing with the FrameScope Pro 2
N2620A User’s Guide 57
7 For specific settings for the Throughput, Latency, Frame Loss
Rate, and Back-to-Back tests, press Next. For details on the
parameters for each test, refer to the corresponding sections.
• For the throughput setup refer to “The Throughput
Settings screen” on page 57.
• For the latency setup refer to “The Latency Settings
screen” on page 58.
• For the frame loss rate setup refer to “Frame loss rate
settings screen” on page 59.
• For the back-to-back setup refer to “Back-To-Back settings
screen” on page 60.
The Throughput Settings screen
Max Data Rate is used for initial
frame speed and performance
calculation. Enter the maximum
data rate of the
network-under-test. If the
maximum data rate is unknown,
the link speed will be used.
Specify the frame length (a minimum
of 64 bytes to a maximum of 1518
bytes) or select Full Range to collect
all frame lengths (64, 128, 256, 512,
768, 1024, 1280, and 1518 bytes)
.
For full duplex networks, you can
select bidirectional testing and
whether the connection is
symmetrical or asymmetrical.
For half-duplex networks,
upstream and downstream can be
tested sequentially.
Select the frame direction to measure
(If destination is a loopback device,
bidirectional option is available)
Select to measure full range or
specify the upstream and
downstream rates
Network connection speed
Duration is the time taken (in
seconds) to transmit frames that
could be of different length, at
different rates.
For better results, adjust the
duration to load the
device-under-test sufficiently.
