Here's a clearer illustration.
class TestDDSPhase(Experiment, AutoDB):
class DBKeys:
core = Device()
dds_bus = Device()
dds0 = Device()
dds1 = Device()
ttl0 = Device()
ttl1 = Device()
@kernel
def run(self):
self.dds0.set_phase_mode(PHASE_MODE_CONTINUOUS)
self.dds1.set_phase_mode(PHASE_MODE_CONTINUOUS)
for i in range(10):
# force DDSs to be phase synchronized at outset of experiment
# this is a temporary override of the default phase mode
with self.dds_bus.batch:
self.dds0.set(3*MHz, phase_mode=PHASE_MODE_ABSOLUTE, phase_offset=0)
self.dds1.set(3*MHz, phase_mode=PHASE_MODE_ABSOLUTE, phase_offset=0)
# emit experiment start pulse on TTL0
self.ttl0.pulse(1*us)
# demonstrate simple spin-echo type pulse sequence
# self.dds0.set(3*MHz, phase_offset=0, phase_mode=PHASE_MODE_CONTINUOUS)
self.ttl1.pulse(.5*us) # first pi/2 pulse
self.dds0.set(3*MHz, phase_offset=0.25, phase_mode=PHASE_MODE_CONTINUOUS)
delay(1*us) # arm time
self.ttl1.pulse(1*us) # middle pi pulse
self.dds0.set(3*MHz, phase_offset=0, phase_mode=PHASE_MODE_CONTINUOUS)
delay(1*us) # arm time
self.ttl1.pulse(0.5*us) # final pi/2 pulse
# delay to let Core_uP catch up
delay(1*ms)

Quick test to see if this behavior is related to the timing of the FTW.
- reset power on DDS box and reset DDS
- run program above
- look on scope

Do you still have any issue with a board flashed with the latest runtime from the conda packages? I pushed the bugfixes only recently. Do you have this commit: 87ea143

I will try to two suggestions you made. It will be a day or two. We are
back running on the old DDS system at the moment. -Joe

OK. Resolved in today's conda build.

Good. Thanks for the quick re-test!
