00h: Stop any received signal to reach the VFRO0 analog output. In order to open the
impedance synthesis feedback it’s necessary to mute the RX analog amplifier, as well.
>00h: Digital gain is inserted in the RX path equal to:
20Log[prog.value/32768]
The prog. value must be expressed in 16 bits signed format: maximum prog. value is
equal to 7FFFh.
00h: Stop any transmit signal, null level is transmitted in the corresponding time slot on
DX output.
>00h: Digital gain is inserted in the TX path equal to:
20Log[prog.value/32768]
The prog. value must be expressed in 16 bits signed format: maximum prog. value is
equal to 7FFFh.
