Example
Disable BODE.MODETIMER:
-->BODE.MODETIMER //
Set to 0 to disable the watchdog
0
-->BODE.MODE // Observe starting state of the Bode mode
0
-->BODE.MODE 1 // Set Bode mode to PRB
-->BODE.MODE // Observe Bode mode state is the same after 0.5 seconds
1
-->BODE.MODE // Observe Bode mode state is the same after 10 seconds
1
Enable BODE.MODETIMER:
-->BODE.MODETIMER 1000 // Set watchdog to 1 second
-->BODE.MODE 1 // Set Bode mode to PRB
-->BODE.MODE // Observe Bode mode state is the same after 0.5 seconds
1
-->BODE.MODE // Observe Bode mode state has been set to zero after 1.0 seconds
0
Enable and reenable BODE.MODETIMER:
-->BODE.MODETIMER 2500 // Set watchdog to 2.5 seconds
-->BODE.MODE 1 // Set Bode mode to PRB
-->BODE.MODE // Observe Bode mode state is the same after 1.5 seconds
1
-->BODE.MODE 1 // Set Bode mode to PRB, resetting the watchdog timer to the original 2.5 second
value
set above.
-->BODE.MODE // Observe Bode mode state is the same after 3.0 seconds after the original enabling
of BODE.MODE 1
-->BODE.MODE // Observe Bode mode state has been set to zero after 4.0 seconds after the original
enabling
of BODE.MODE

BODE.MODE is left at the value you set it to.
Uses pseudo random binary (PRB) excitation. PRB is a signal that is always
+/- peak amplitude, varying only in phase.
PRB excitation results in a flat excitation frequency spectrum. PRB also
results in a high peak excitation amplitude, which can help minimize friction
in a frequency response test.
PRB excitation repeats every (2^BODE.PRBDEPTH)/BODE.EXCITEGAP
drive samples. This repetition can be used to reveal the effects of friction.
