multiple modular transmitters where the certification is based on testing each of them in
a stand-alone configuration.It is important to note that host product manufactures should
not assume that because the modular transmitter is certified that they do not have any
responsibility for final product compliance.
c) If the investigation indicates acompliance concern the host product manufacture is
obligated to mitigate the issue.Host products using a modular transmitter are subject to
all the applicable individual technical rules as well as to the general conditions of
operation in Sections 15.5,15.15,and 15.29 to not cause interference.The operator of
the host product will be obligated to stop operating the device until the interference has
been corrected.
Below are steps for on test mode:

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-f <float> Tx RF frequency in MHz [800:1000]
-r <int> Radio type (SX1255:1255, SX1257:1257)
--dig <uint> Digital gain trim, [0:3]
0:1, 1:7/8, 2:3/4, 3:1/2
--mix <uint> Radio Tx mixer gain trim, [0:15]
15 corresponds to maximum gain, 1 LSB corresponds to 2dB step
--pa <uint> PA gain trim, [0:3]
--mod <char> Modulation type ['LORA','FSK','CW']
--sf <uint> LoRa Spreading Factor, [7:12]
--bw <uint> LoRa bandwidth in kHz, [125,250,500]
8. Additional testing,Part 15 subpart B disclaimer
The final host/module combination need to be evaluated against the FCC Part 15B
criteria for unintentional radiators in order to be properly authorized for operation as a
Part 15 digital device.
The host integrator installing this module into their product must ensure that the final
composite product complies with the FCC requirements by a technical assessment or
evaluation to the FCC rules,including the transmitter operation and should refer to
guidance in KDB 996369.
