This section covers sensitivity testing using Calibrator Tool. If Calibrator Tool has not been set up, please navigate to the Getting Started with Calibrator Tool section before continuing. Use the below example flows as references for how to perform a sensitivity test. For further information on Calibrator Tool, navigate to the Calibrator Tool guides for the CC33xx and CC35xx located in the respective SDKs.

VSG:

• Configure at the same frequency selected in Calibrator Tool
• Import a waveform matching the data rate selected in Calibrator Tool
• Set TX power slightly above the datasheet sensitivity value to account for loss

CC33xx example flow on channel 6, in broadcast mode, with 11ax SU preamble type, MCS7 rate:

calibrator wlan0 plt power_mode on
calibrator wlan0 cc33xx_plt tune_channel 6 0 0
calibrator wlan0 cc33xx_plt set_manual_calib -rx 1
calibrator wlan0 cc33xx_plt start_rx -source_mac FF:FF:FF:FF:FF:FF -preamble_type 5 -rate 20
calibrator wlan0 cc33xx_plt get_rx_stats
calibrator wlan0 cc33xx_plt stop_rx

CC35xx example flow on channel 6, in broadcast mode, with 11ax SU preamble type, MCS7 rate:

wlan_start
calibrator power_mode on
calibrator tune_channel 6 0 0
calibrator set_manual_calib -rx 1
calibrator start_rx -source_mac FF:FF:FF:FF:FF:FF -preamble_type 5 -rate 20
calibrator get_rx_stats
calibrator stop_rx

Note: To obtain a fresh set of statistics for each measurement, repeat commands 4-6. Omitting the stop/start cycle causes statistics to accumulate as a running total.

Note: Figure 5-6 provides assistance when tuning the device. The parameters must be typed in the order they appear.

Note: For best results, this test and any other RX Sensitivity test must be performed in an RF Shielded Enclosure. Additionally, make sure to send a specific number of packets from the VSG as a reference to compare with how many packets the DUT receives.

If experiencing poor performance or no packets are being received, reference the Troubleshooting/FAQ section.
