ATP Configuration Wizard

The Acceptance Test Plan (ATP) defines a few procedures, under which several test cases are defined. The input parameters and format are different from the DOCSIS 3.1 carrier node. As a result, this ATP configuration wizard is provided on the toolbar under DOCSIS 3.1 node to allow you to easily configure the ATP test cases or customized cases.

Procedure

Choices: 1.1 Single DS OFDM | Customized

Default: 1.1 Single DS OFDM

Select the procedure for the test case configuration.

When changing to 1.1 Single DS OFDM, all the parameters below will be updated to the correct values defined in the ATP specification.

Test Case

Range: 1 to 30

Default: 1

Enter the ID for the preset of the ATP test case.

This is only configurable when Procedure is set to 1.1 Single DS OFDM. When changing to a new value, all the parameters below will be updated to the correct values defined in the ATP specification.

ModulationDefault

Choices: 16 QAM | 32 QAM | 64QAM | 128 QAM | 256 QAM | 512 QAM | 1024 QAM | 2048 QAM | 4096 QAM | 8192 QAM | 16384 QAM

Default: 4096 QAM

Enter the default modulation scheme of the test case.

The input format can be (1024-QAM as an example): 1024, 1024-QAM, or 1024QAM. Input values that are not the power of 2 are rounded to the largest power of 2 value that is less than the input.

SubcarrierSpacing (kHz)

Choices: 25 | 50

Default: 25

Enter the subcarrier spacing of the test case.

SubCarrierZero (MHz)

Range: 200 to 2000

Default: 250.6

Enter the subcarrier zero of the test case.

LowerEdgeFreq (MHz)

Range: 200 to 2000

Default: 258

Enter the lower edge frequency of the test case.

UpperEdgeFreq (MHz)

Range: 200 to 2000

Default: 280

Enter the upper edge frequency of the test case.

CyclicPrefix (Ncp)

Range: 64 to 2048

Default: 192

Enter the cyclic prefix of the test case.

RolloffPeriod (Nrp)

Range: 0 to 512

Default: 0

Enter the rolloff period of the test case.

Power at CM Input (dBmV/24 MHz)

Range: -30 to 30

Default: 0

Enter the power at CM input of the test case.

Exclusion Bands (MHz or individual subcarriers)

Enter the exclusion bands of the test case.

This is only configurable when Procedure is set to Customized. The exclusion bands can be input as follows:

• by frequency range (in MHz), for example [871 - 897]

• by individual subcarrier index, for example 348,349

• by a combination of the two methods above, using a comma as separator (see example below)
