Network Testing with the FrameScope Pro 2

N2620A User’s Guide 57

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.
