7.2 Calibration procedures
[5] Select the range 5 µs to 105 µs on the period selection knob. Turn the 10
turns adjustment knob to its last position. Adjust the adjustable capacitor max
105 µs adj (4) in order to obtain a 105 µs long period.
[6] Turn the 10 turns adjustment knob to its first position. Ajust the pot Period
min adj (1) in order to have a period of 5 µs.
[7] Repeat steps 5) and 6) in order to obtain 105±1 µs and 5±0,1 µs for the two
settings of the Period knob.
[8] Choose the range 0.2 µs to 2.2 µs. Turn the 10 turns adjustment knob to its
last position.. Adjust the max 2,2 µs adj capacitor (2) in order to obtain a period
of 2.2 µs.
[9] Turn the 10 turns adjustment knob to its first position. Check that the period
is 200 ns. If this is not the case, re-adjust the pot 50 ns adj (5) in order to obtain
200 +/-20 ns. (In general, it is not possible to go below 210 ns).
[10] Choose the range 0.5 µs to 10.5 µs. Pot 10 turn Period on 10. Adjust
capacitor max 10,5 µs adj (3) in order to have a period of 10,5 µs.
[11] Turn the 10 turns adjustment knob to its first position. Check the that period
is of 0.6 +0/-0.1 µs.
