HAM2 Picomotor Test Using Test Setup :

We tested the picomotor 3 (supposedly ISS H1) and 5 (supposedly ISS pickoff) using the picomotor test setup and did not see any signal change in the StripTool window except for the 3X channel. 3X channel showed some increase in signal amplitude but would settle back down after the drive was complete. 

Picometer Cable Capacitance Measurement:

We measured the capacitance across each pair of connector and got the following results:

1X: 209 nF  (J1: 1-14)                         5X: 4.0 nF  (J2: 1-14) 

1Y: 208 nF  (J1: 2-15)                         5Y: 3.9 nF  (J2: 2-15)

2X: 211 nF  (J1: 3-16)                         6X: 3.9 nF  (J2: 3-16)

2Y: 212 nF  (J1: 4-17)                         6Y: 3.9 nF  (J2: 4-17)

3X: 217 nF  (J1: 5-18)                         7X: 3.9 nF  (J2: 5-18)

3Y: 4.3 nF   (J1: 6-19)                         7Y: 3.9 nF  (J2: 6-19)

4X: 201 nF  (J1: 7-20)                        8X: 211 nF  (J2: 7-20)

4Y: 211 nF  (J1: 8-21)                         8Y: 211 nF  (J2: 8-21)

Summary:

           1, 2, 3X, 4 and 8 has picomotor connected

           3Y, 5, 6, 7 are empty
