DL Test Model

The Cell ID is assigned based on the current carrier index, i.e. Carrier 1 use Cell ID 1, Carrier 2 use Cell ID 2.

Bandwidth

Choices:

Downlink: Based on the Table 5.3.2-1 and 5.3.2-2 in 38.104

Uplink: Based on the Table 5.3.2-1 in 38.101-1 and 38.101-2

Selects the bandwidth configuration for the carrier.

Numerology

Selects the numerology of the test model. The choices are related to the selected bandwidth.

Duplex Type

Choices: TDD | FDD

Default: TDD

Selects the duplex type of the test model.

Transmission Periodicity

Sets the periodicity of DL-UL pattern. The choices are related to numerology.

Read-only.

Number of Downlink Slots

Sets the number of consecutive full DL slots at the beginning of each DL-UL pattern. The range is related to the numerology and slot configuration period.

Read-only.

Number of Downlink Symbols

Range: 0 ~ 14 for Normal CP; 0 ~ 12 for Extended CP

Sets the number of consecutive DL symbols in the beginning of the slot following the last full DL slot.

Read-only.

Number of Uplink Slots

Sets the number of consecutive full UL slots at the end of each DL-UL pattern. The range is related to the numerology and slot configuration period.

Read-only.

Number of Uplink Symbols

Range: 0 ~ 14 for Normal CP; 0 ~ 12 for Extended CP

Sets the number of consecutive UL symbols in the end of the slot preceding the first full UL slot.

Read-only.

Number of Special Slots

Displays the number of special slots.

Read-only.

TDD Slot Allocation

Displays the TDD slot allocation for one period.

Test Model

Choices: NR-FR1-TM1.1 | NR-FR1-TM1.2 | NR-FR1-TM2 | NR-FR1-TM2a | NR-FR1-TM3.1 | NR-FR1-TM3.1a | NR-FR1-TM3.2 | NR-FR1-TM3.3 | NR-FR2-TM1.1 | NR-FR2-TM2 | NR-FR2-TM2a | NR-FR2-TM3.1 | NR-FR2-TM3.1a

Default: NR-FR1-TM1.1

Selects the Test Model to configure. The choices are defined in the section 4.9.2 of 38.141. A description of the currently selected test model appears in the hint window directly below.

Modulation

Choices: QPSK | 16QAM | 64QAM

Default: 64QAM

Set the Modulation Type for NR-FR2-TM2 or NR-FR2-TM3.1.

Number of Layers

Choices: 1 | 2

Sets the Number of Layers (Rank) for Test Model 1.1, two layers MIMO transmission is used for TAE requirement, single layer is used for others.

Phase Compensation

For waveform playback mode:

Choices: Auto | Auto (Real-time) | Manual | Manual (Real-time) | Off

For real-time uplink mode:

Choices: Auto | Manual | Off

Default: Auto

Sets the phase compensation mode on baseband signal before upconversion.

Auto | Auto (Real-time): Use the RF frequency from the instrument node.

Manual | Manual (Real-time): Enter the RF frequency manually.

Off: Disable phase compensation on baseband signal.

(Real-time) means the phase compensation is done using FPGA inside the instrument.

DCI/DLSCH Payload Data

Choices: PN9 | PN23

Default: PN23

Select the PN type for Downlink Test Model.
