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

1Mbps (0)

Receiver is set to use the LE 1M PHY.

2Mbps (1)

Receiver is set to use the LE 2M PHY.

Coded (2)

Receiver is set to use the Coded PHY.

modulation index specifies the type of modulation index at the generator. The default value is Standard.

Standard (0)

The packets are generated with standard modulation index.

Stable (1)

The packets are generated with stable modulation index.

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 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.

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.

/images/reference/en-XX/help/375699E-01/ii32.gif

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