H.P. Calib.

Home position detector adjustment utility:

1. Bring carriage to Home position (fast motion).
   
2. Read micro steps offset.
   
3. Adjustment is ok for 125 < offset < 375.

*) Can be run in the loop.

RF Driver

RF Driver gain adjustment utility:

1. Set modulator to value = 10V.
   
2. Displays Rf Level Or Light Intensity.
   
3. Displays Rf Level Graph for 0 to 4096 values (step 15).

Cri PLL

Cri Pll phase adjustment utility:

1. Adjust P101 on CRI Board for getting 4.5V between U101-3 and GND.
   
2. Connect Oscilloscope Ch1 to TS301-4.
   
3. Connect Oscilloscope Ch2 to TS301-5.
   
4. Adjust P102 on CRI Board for all frequencies 25ns < PHASE < 45ns.
   
5. Manual frequency swap and verify phase and frequency.

Strobe5 VCO

Strobe VCO adjustment utility:

1. Adjust L3 or L4 coil for High or Low frequency range.
   
2. Connect Oscilloscope to PLL_OUT.
   
3. Connect TP6 to GND.
   
4. Connect TP7 (and OMC Diag Analog input) to external voltage supply (0-10 Volt).
   
5. Verify that the PLL_OUT frequency is in range for 3 voltages inputs for both PLL ranges.

*) In future Measure DATA_EXPOSE clocks by OMC, multiply the result by 10 and display the result as PLL_OUT frequency.

Strobe5 Phase

Strobe Phase adjustment utility (for Low PLL range):

1. Connect Oscilloscope Ch1 to TP1.
   
2. Connect Oscilloscope Ch2 to TP2.
   
3. Adjust P1 for 50-70 nsec between TP1 and TP2.

*) PLL is been locked for resolution 100 (low range).
