pzt2 mod signals matched slider vals for both pitch and yaw
pzt2 yaw mon output = 6
pzt2 pitch mon output = 11.3
From the PZT connector-converter board we determined the following pin-outs:
X=Yaw: red=1, white=14, black=3
Y=Pitch: red=2, white=15, black=16
We believe that red is signal, white/black/shield are all ground. We also believe (although this is from the PMC PZT) that the expected capacitance of the PZTs should be in the 100's of nF range.
Here are the readings from the two PZT dsub connectors:
pin 1:14 PZT1 = ".003" on 2uF scale
PZT2 = ".184"
pin 2:15 PZT1 = ".002" on 2uF scale
PZT2 = ".202"
So we think this means (given this crappy capacitance meter) that PZT2 is showing roughly 200nF, which sounds ok, but that PZT1 is indeed bad.
So next we investigate the PZT2 driver.
