Loopback Test Mode
Title LOOP BACK
Summary
Receives data on LO Frequency for data packets and then retransmits
this data on the same channel at transmit level ‘lvl’. Highside
reception is off and attenuation is set to 0. Expected reception
frequency, txrx_freq (default = 12500 microsecs) with single slot
packets returned lb_offs after receipt (default = 1875 microsecs).
Defaults can be changed. See Configuration Commands section.

Spec Name
None, but note that this test RCV/CA/01/C to RCV/CA/06/C to be
performed in loopback without using the LMP commanded loopback
test mode.
RCV/CA/01/C to RCV/CA/06/C to be performed in loopback, but
without using the LMP commanded loopback test mode.
Test Arguments
LO Freq (Carrier Frequency MHz)= 2402 to 2480 (default =
2432)
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).
Return Data None
