3.1.3.2 CW

The following table provides the command syntax for CW TX mode.

Table 3-3. Start TX CW: After Initialization
Command Syntax MCHPRT 8 X Y Z A B C D L F
X X refers to TX channel: 1 to 14
  • 1 – Channel 1 (2412 MHz)
  • 6 – Channel 6 (2437 MHz)
  • 14 – Channel 14 (2484 MHz)
Y Z Y refer to Rate, Z refers to Preamble:
Rate = 0 Preamble = 0 11b 1 Mbps
Rate = 1 Preamble = 0 11b 2 Mbps
Rate = 2 Preamble = 0 11b 5.5 Mbps
Rate = 3 Preamble = 0 11b 11 Mbps
Rate = 0 Preamble = 1 11g 6 Mbps
Rate = 1 Preamble = 1 11g 9 Mbps
Rate = 2 Preamble = 1 11g 12 Mbps

Rate = 3

Preamble = 1 11g 18 Mbps
Rate = 4 Preamble = 1 11g 24 Mbps
Rate = 5 Preamble = 1 11g 36 Mbps
Rate = 6 Preamble = 1 11g 48 Mbps
Rate = 7 Preamble = 1 11g 54 Mbps
Rate = 0 Preamble = 2 11n MCS - 0 0x80
Rate = 1 Preamble = 2 11n MCS - 1 0x81
Rate = 2 Preamble = 2 11n MCS - 2 0x82
Rate = 3 Preamble = 2 11n MCS - 3 0x83
Rate = 4 Preamble = 2 11n MCS - 4 0x84
Rate = 5 Preamble = 2 11n MCS - 5 0x85
Rate = 6 Preamble = 2 11n MCS - 6 0x86
Rate = 7 Preamble = 2 11n MCS - 7 0x87
A A refers to bandwidth:

0/1 – 20 MHz

B B refers to Digital Gain (Bypass mode):

Range: -20 to 0

DG: Dynamic Gain

C C refers to PA gain (Bypass mode):
  • ATWILC1000/ATWINC15X0 – 18, 15, 12, 9, 6, 3
  • ATWILC3000/ATWINC3400 – 18, 15, 12, 9, 6, 3
DG: Dynamic Gain
D D refers to PPA gain (Bypass mode):
  • ATWILC1000/ATWINC15X0 – 9, 6, 3, 0
  • ATWILC3000/ATWINC3400 – 20, 18, 15, 12, 6, 0
DG: Dynamic Gain
L L refers to length:

0 – 1500

Maximum limit is 1500

F F mean Frequency offset : -50 to +50 base on Crystal

XO: eFuse XO value

Example MCHPRT 8 1 7 2 0 -10 18 6 1500 0

Channel 1. MCS 7 – 20 MHz, length 1500, 0 ppm offset DG – 10, PPA 6, PA 18 CW mode
