power#

uint16_t sl_si91x_request_tx_test_info_t::power

Range : 2 - 18 dBm. Note

• 1. User can configure the maximum power level allowed for the given frequncey in the configured region by providing 127 as power level.

• 2. User should configure a minimum delay (approx. 10 milliseconds) before and after sl_si91x_transmit_test_start API to observe a stable output at requested dBm level.

rate#

Data Rates#

length#

uint16_t sl_si91x_request_tx_test_info_t::length

mode#

uint16_t sl_si91x_request_tx_test_info_t::mode

TX test mode mode.

0 - Burst Mode.

1 - Continuous Mode.

2 - Continuous wave Mode (non modulation) in DC mode.

3 - Continuous wave Mode (non modulation) in single tone mode (center frequency -2.5 MHz).

4 - Continuous wave Mode (non modulation) in single tone mode (center frequency +5 MHz). Burst mode: DUT transmits a burst of packets with the given power, rate, length in the channel configured. The burst size will be determined by the number of packets and if its zero, then DUT keeps transmitting till a sl_si91x_transmit_test_stop API is called.

Continuous Mode: The DUT transmits a unmodulated waveform continuously

Continuous Wave Mode (Non-Modulation) in DC Mode: The DUT transmits a spectrum only at the center frequency of the channel. A basic signal with no modulation is that of a sine wave and is usually referred to as a continuous wave (CW) signal. A basic signal source produces sine waves. Ideally, the sine wave is perfect. In the frequency domain, it is viewed as a single line at some specified frequency.

Continuous Wave Mode (Non-Modulation) in single tone Mode (Center frequency -2.5 MHz): The DUT transmits a spectrum that is generated at -2.5MHz from the center frequency of the channel selected. Some amount of carrier leakage will be seen at Center Frequency. For example, for 2412 MHz, the output would be seen at 2409.5 MHz.

Continuous Wave Mode (Non-Modulation) in single tone Mode (Center frequency +5 MHz): The DUT transmits a spectrum that is generated at 5MHz from the center frequency of the channel selected. Some amount of carrier leakage will be seen at Center Frequency. For example, for 2412MHz, the output would be seen at 2417 MHz.
