VISA resource name specifies the name of the resource to be opened. This parameter also specifies the VISA session and class.

ci32.gif

channel number specifies the Bluetooth transmit channel number of the generated signal. The default value is 0.

ci32.gif

payload length specifies the length, in bytes, of payload data in each packet that the DUT transmits. The default value is 37.

ci32.gif

LE pattern type specifies the type of payload to use for the LE packet. The default value is PRBS9. Payload type values of PRBS9, 11110000, and 10101010 must be supported by the DUT. The remaining payload type values are optional.

PRBS9 (0)

Specifies that the bit sequence is PRBS9.

11110000 (1)

Specifies that the bit sequence is 11110000.

10101010 (2)

Specifies that the bit sequence is 10101010.

PRBS15 (3)

Specifies that the bit sequence is PRBS15.

11111111 (4)

Specifies that the bit sequence is 11111111.

00000000 (5)

Specifies that the bit sequence is 00000000.

00001111 (6)

Specifies that the bit sequence is 00001111.

01010101 (7)

Specifies that the bit sequence is 01010101.

ci32.gif

PHY specifies the type of the packet to be transmitted by the physical layer of the DUT. The default value is 1Mbps.

1Mbps (0)

Transmitter is set to use the LE 1M PHY.

2Mbps (1)

Transmitter is set to use the LE 2M PHY.

Coded 125kbps (2)

Transmitter is set to use the LE Coded PHY with S = 8 data coding.

Coded 500kbps (3)

Transmitter is set to use the LE Coded PHY with S = 2 data coding.

ci32.gif

Direction Finding Mode specifies the mode of direction finding. The default value is Disabled.

Disabled (0)

Specifies that the LE packet does not have fields required for direction finding.

Angle of Arrival (1)

Specifies the LE packets uses the angle of arrival method of direction finding.

Angle of Departure (2)

Specifies the LE packet uses angle of departure method of direction finding.

CTE Length specifies the length of the constant tone extension field in the generated signal. This value is expressed in seconds. This parameter is applicable only when you set the Direction Finding Mode parameter to either Angle of Arrival or Angle of Departure. The default value is 160 microseconds.

cdbl.gif

CTE Slot Duration specifies the length of the antenna switching and sampling slots in the constant tone extension field. This value is expressed in seconds. The default value is 1 us.

1 us (0.000001)

Specifies that length of the antenna switching and sampling slots in the constant tone extension field is 1 microseconds.

2 us (0.000002)

Specifies that length of the antenna switching and sampling slots in the constant tone extension field is 2 microseconds.

c1di32.gif

Antenna IDs specifies the array of Antenna IDs in the antenna switching pattern. The length of Antenna IDs array must be equal to Length Of Switching Pattern. 

ci32.gif

Switching Pattern Length specifies the length of the antenna switching pattern. The default value is 0.

error in describes error conditions that occur before this node runs. This input provides standard error in functionality.

iio.gif

VISA resource name out returns the resource name to which a VISA session is opened and the resource class. The class name matches the VISA resource name parameter.

ii32.gif

status returns the status of the transmitter test command. The DUT receives and executes the transmitter test command if the status parameter returns a 0x00 value. The transmitter test command fails if the status parameter returns a non-zero (0x01-0xFF) value.
