WERA HF Radar Software - Header Mode Bits

The following table describes the mode bits which can be set in the header:

MD:
[11] [10] [9] [8]
[7] [6] [5] [4]
[3] [2] [1] [0]

Bit Position Value Function
[0] 0 Line power for power amplifier is switched OFF
  1 Line power for power amplifier is switched ON
[1] 0 Internal calibration mode is switched OFF
  1 Internal calibration mode is switched ON
[2] 0 IfM internal use (jitter)
  1 IfM internal use (jitter)
[3] 0 90.742153846154 MHz system clock
  1 90.000000000000 Mhz system clock
[4] 0 Leave TX DDS at DC
  1 Set TX DDS to WERA working frequency
[5] 0 Leave RX DDS at DC
  1 Set RX DDS to WERA working frequency
[6] 0 IfM internal use (LAH)
  1 IfM internal use (LAH)
[7] 0 Master (chirp up)
  1 Slave (chirp down)
[10] 0 Disable FMICW
  1 Enable FMICW
[9] [8] 0 0 FMICW sequence #0
  0 1 FMICW sequence #1
  1 0 FMICW sequence #2
  1 1 FMICW sequence #3
[11] 0 Chirps up or down
  1 Triangular Chirps

The header mode bits are encoded using three Hexadecimal Digits, e.g.:

1110 0011 0001 is encoded as MD:E31
