Title RX LOOP BACK
Summary Transmit PRBS9 data on LO Frequency at transmit level and listen for
transmissions in the next slot but one. Sends reports as RXDATA1 back to
the host once per second (configurable). Highside reception is off and
attenuation is set to 0. Default is single-slot packets (configurable with
config_freq). This is designed to be used with a second unit in
LOOP_BACK test mode.
Related Test
Spec Name
None, but note that this test allows transmission to and reception from
Implementation under Test (IUT) in LOOP_BACK test mode with RSSI
and BER calculated from FEC.
Test Arguments
LO Freq (Carrier Frequency MHz)= 2402 to 2480
Power (Ext, Int) = gain of external amplifier (if present) and internal
amplifier. Ext value is specific to the design and Int value is 0 to 63
(Default = 50).
Note With a second unit execute CFG UAP/LAP to set the Bluetooth address.
Execute LOOP BACK then execute CFG UAP/LAP to set the same BT
address on the Equipment under Test (EUT) before executing RX LOOP
BACK.
Return Data NP = Number of packets
NGP = Number of good packets
NCP = Number of corrected packets
RSSI = Received Signal Strength Indication
True = RSSI is reliable, otherwise false
Exit Click on Reset Chip.
