Description
Transmitter gain settings for TXLO output
Transmitter gain settings for TXHI output
Tx ramp-up delay programming: 00–1 s, 01–2 s, 10–3 s, 11–4 s. Ramp-up time always 1 s.
Tx carrier leakage calibration:
Write: with test mode, these bits set the offset.
Read: in normal mode, automatically controlled settings can be read out here (sign plus three bits).
Code: {txosXon,txosXval} = ‘0xxxx’
{txosXon,txosXval} = ‘11000’
Tx offset correction, I channel, value (sign plus three bits)
Tx offset correction, I channel ON
Tx offset correction, Q channel, value (sign plus three bits)
Tx offset correction, Q channel ON
Description
VCO band.
Write: with test mode, these bits set the VCO band.
Read: in normal mode, the result ot the calibration (VCOCAL) can be read out here (0000 = highest frequencies).
VCO calibration error flag (no band with low enough frequency could be found).

Description
Write: In RXMGC mode, this sets the receiver gain.
Read: In other modes, the AGC controlled gain is available for readout here.
Bit positions: 0–plus1dB; 1–vga2dB; 2–vga4dB; 3–vga8dB; 4–vga16dB; 5–vga10dB; 6–filter6dB2; 7–filter10dB;
8–filter6dB1; 9–lna16dB
DC offset cancellation cornerpoint select.
Write: In RXMGC mode, this sets the cornerpoint.
Read: In other modes, the cornerpoint as controlled by the AGC is available for readout here.
Code: 00–10 kHz, 01–100 kHz, 10–1 MHz, 11–10 MHz
Use 10 MHz offset cancellation cornerpoint for brief period after each gain change
Receiver output driver manual offset adjustment. Code: {rxosXon,rxosXval} = ‘0xxxx’
{rxosXon,rxosXval} = ‘10000’
{rxosXon,rxosXval} = ‘10001’
Rx offset correction, I channel, value (sign plus three bits)
Rx offset correction, I channel, ON
Rx offset correction, Q channel, value (sign plus three bits)
Rx offset correction, Q channel, ON
AGC with high Signal-to-Noise (switch LNA at step 52 instead of step 60).
Recommended to set to ‘1’.
