PDU Payload Setting (LL_DATA, Reference Packet)

When Reference is the selected Packet Type and CTEInfo Present is set to True, the CTE Info Setting properties appear.

Payload Distribution

Choice: Single Packet | Multiple Packet

Default: Single Packet

Double-click or use the drop down menu to select the distribution type of packet payload.

When Single Packet is selected, the software creates a waveform that consists of one Bluetooth packet. When downloaded to the signal source, the waveform is repeatedly played back resulting in a packet sequence comprised of identical packets. When Multi Packet is selected, the software creates a waveform that consists of a multiple packet sequence. A data pattern is distributed into the payload portion of each packet in the sequence. Once downloaded to the instrument, the signal generator repeatedly plays back the entire packet sequence. The net result is the ability to configure longer data sequences for analysis.

Payload Data

Reference Packet:

Choice: PN9 | S11110000 | S10101010 | S11111111 | S00000000 | S00001111| S01010101 | PN15 | User Defined

Default: PN9

Click to set the data type of the packet payload:

When continuous (Data Continuous is set to ON) PN9 or PN15 is selected, the software automatically configures the Length and Repetitions fields. The number of packets required to accommodate the selected continuous PN pattern is also automatically determined and updated the number of bit

When change the payload data type to PN or fixed byte pattern, the payload header byte will update according to the payload content field table below:

Payload Content Field	Payload Description
0000	PRBS9 sequence
0001	Repeated ’11110000’ sequence
0010	Repeated ’10101010’ sequence
0011	PRBS15 sequence – reserved for future use
0100	Repeated ’11111111’ sequence - reserved for future use
0101	Repeated ’00000000’ sequence - reserved for future use
0110	Repeated ’00001111’ sequence - reserved for future use
0111	Repeated ’01010101’ sequence - reserved for future use

If User Defined Bits is selected as the data pattern, the number of bits, shown in the Data Length field, equals s in the user data file, up to the number of bits allowed for that packet type. Any remaining bits in the user data file beyond the maximum amount will be truncated.

LL_DATA:

Choice: PN9 | PN15 | User Defined

Default: PN9

Click to set the data type of the packet payload:

Data Continuous

Choice: On | Off

Default: On

Double-Click or use the drop-down menu to set the continuous state of the packet payload data.

This setting is only available when Payload Distribution is set to Multiple Packet.

Data Repetition

Set the repetition number of the packet payload data.

This setting is only available when Payload Distribution is set to Multiple Packet and Data Continuous is set to Off.

Data Length

Set the number of total bits contained in the payload data.

This setting is only available when Payload Distribution is set to Multiple Packet and Data Continuous is set to Off.

Number Of Full Packets

Display the number of full packet occupied by the packet payload.

Number Of Partial Packets

Display the number of partial packet occupied by the packet payload. Because the payload portion of each packet is filled to capacity if possible, the number of partial packets appended to the end of a packet sequence will always be 0 or 1.

Number Of Padding Packets

Choice: 0 | 1

Default: 0

Sets the number of padding packets occupied by the packet payload.

CTE Info Setting

This property table appears only when Packet Type is set to Reference and CTEInfo Present is set to True.

CTE Time

Range: 2 to 20

Default: 2

Set the CTE Time field of CTE Info Header to indicate the length of the Constant Tone Extension in units of 8 us.

CTE Type

Choice: AoA Constant Tone Extension | AoD Constant Tone Extension with 1 us slots | AoD Constant Tone Extension with 2 us slots

Default: AoA Constant Tone Extension

Coupling: If the CTE Type is set to AoA Constant Tone Extension, the Slot Length will be visible, otherwise will hide

Set the CTE Type field of CTE Info Header to indicate the type of the Constant Tone Extension and duration of the switching slots.

DUT Type

Choice: Receiver | Transmitter

Default: Receiver

Coupling: For the transmitter, the Slot Length, Antenna Number, and Amplitude-Phase parameters are not available.

Set the DUT type to indicate that the IQ sampling is at Receiver or Transmitter.

For the receiver,a continuous wave at the carrier frequency will be sent in the switch slot.

For the transmitter, the switch slot will be idle for AoD, and continuous transmission for AoA.

Slot Length

Choice: 1us | 2us

Default: 1us

Set the slot length for AoA when the packet contains the Constant Tone Extension field.

Antenna Number

Range: 2 to 4

Default: 2

Coupling: It determines the number of rows in the Antenna Configuration dialog

Set the number of antennas the packet contains the Constant Tone Extension field.

Amplitude-Phase

Range:

Amplitude (ratio): 0.5 to 2

Phase: -180 to 180 degree

Default: 1,0;1,0

Coupling: The number of pairs of the Amplitude-Phase is consistent with the value of AntNum

Opens a dialog where you can set the Amplitude-Phase characteristics applied to each antenna.

The amplitude value is expressed as a ratio.

The phase value is expressed in degrees.
