Hello Support,
We need to do PER testing on our device using a signal generator (SG) at various amplitudes. It seems the best way to handle this would be to output a serial stream from a microcontroller into the SG and have it modulated for the receiving DUT. Because there's additional information (CRC, 30/32 sync) appended to the packet by the radio's packetizer, we need some help getting a test packet assembled. Will you please provide a serialized packet, including CRC checksum for the following packet...
preamble (4) + length (8) + sync (MG) + payload (ST_PER) + checksum
The radio settings we are using is as follows...
FSCTRL1 = 0x08; // Frequency Synthesizer Control
FSCTRL0 = 0x00; // Frequency Synthesizer Control
FREQ2 = 0x5C; // Frequency Control Word, High Byte
FREQ1 = 0x5C; // Frequency Control Word, Middle Byte
FREQ0 = 0xEC; // Frequency Control Word, Low Byte
MDMCFG4 = 0x78; // Modem configuration
MDMCFG3 = 0x83; // Modem Configuration
MDMCFG2 = 0x13; // Modem Configuration
MDMCFG1 = 0x23; // Modem Configuration
MDMCFG0 = 0x8A; // Modem Configuration
CHANNR = 0x4A; // Channel Number
DEVIATN = 0x44; // Modem Deviation Setting
FREND1 = 0x56; // Front End RX Configuration
FREND0 = 0x10; // Front End TX Configuration
MCSM0 = 0x14; // Main Radio Control State Machine Configuration
FOCCFG = 0x16; // Frequency Offset Compensation Configuration
BSCFG = 0x6C; // Bit Synchronization Configuration
AGCCTRL2 = 0x43; // AGC Control
AGCCTRL1 = 0x40; // AGC Control
AGCCTRL0 = 0x91; // AGC Control
FSCAL3 = 0xA9; // Frequency Synthesizer Calibration
FSCAL2 = 0x0A; // Frequency Synthesizer Calibration
FSCAL1 = 0x00; // Frequency Synthesizer Calibration
FSCAL0 = 0x11; // Frequency Synthesizer Calibration
TEST2 = 0x88; // Various Test Settings
TEST1 = 0x31; // Various Test Settings
TEST0 = 0x09; // Various Test Settings
PA_TABLE0 = PA_Level; //0xFE; // PA Power Setting
PKTCTRL1 = 0x04; // Packet Automation Control
PKTCTRL0 = 0x05; // Packet Automation Control
ADDR = 0x00; // Device Address
PKTLEN = 0xFF; // Packet Length
Thanks for your help,
