Configuration of speed test in the DOCSIS analyzer
The speed test (data throughput measurement) works in uplink and downlink directions. The test is
based on transmission of data from or to an FTP server that is connected to the head end. Several
parameters must be stored in the measuring instrument for this test.
You can use
MODE
->
Settings
->
DOCSIS Analyzer
->
Speed Test
to configure the test.
This section offers four profiles which also allow you to store the data for multiple HFC clusters or
head ends.

You can use keys
F1
to
F4
to select a profile. You can edit the selected profile using the steps
described below. At the same time, the parameters of the most recently selected profile are
automatically selected for future speed tests of the DOCSIS analyzer.
You can use the
↑
/
↓
keys to select the desired profile entry field and open the input mask to change
individual parameters by pressing
ENTER
. You can use the measuring instrument’s numerical
keypad to enter not only numbers, but also letters and special characters. The individual keys
include both their numerical value, and a label of the letters they can be used to enter. By pressing
a key multiple times, you can switch between the individual letters, uppercase and lowercase, and
the numerical value. You can enter a space with the
0
key, and the
1
key can be used for various
special characters.
Enter the IP address in the usual format: the username and password of the FTP server and the
name (and path, where applicable) of the download file and the profile name are alphanumeric
character strings.
16 characters are available for the password, 18 for the username and 30 for the file name or file
path. The value range for the downlink file size is 0.1 to 2,048 MByte. The uplink file size is 0.1 to
500 MByte. Even though, for example, a profile is only configured for a downstream test, a valid
figure must be entered for the upstream file size. When you are done entering a value, use the
ENTER
key to skip straight to the next value. The parameters are only saved when you select
APPLY
, you then exit the menu. Using the
APPLY
key, you can permanently store all the
parameters in the measuring instrument’s memory. The name entered for the profile – which can
be no more than 10 characters long – is displayed above the corresponding F key after you reopen
the speed test configurator.
