Sayma SAWG: startup kernel, frequency0 in loop, amplitude modulation

[jbqubit]

• 4.0.dev+1133.g0b086225
• Sayma_AMC s/n -6 (the one I've been using for two weeks now)
  • memtests and locks fail in fewer than 1/50 (I'm keeping scorecard)
• HMC7043 reset pullup applied
• running as startup kernel
• kernel continued to run for 5 minutes before I reset board, but can't ping

I've seen this same behavior loading four times.

[trxw]

For one thing, the amplitude needs to be set between 0-1 and not 100MHz

for sawg in self.sawgs:
            sawg.reset()
            delay(500*us)
            sawg.amplitude1.set(100*MHz)

[jbqubit]

Ah right. With sawg.amplitude1.set(0.5) this works as startup kernel as in the past. Glad this is a typo and not a regression. :)

[trxw]

@sbourdeauducq Shouldn't there be a bound checking for amplitude?
