7.3 Crystal Sensor Emulator
IPN 760-601-G2
NOTE: 760-601-G2 is fully compatible with all Thin Film Deposition Controllers.
The Crystal Sensor Emulator option is used in conjunction with the Thin Film
Deposition Controller to rapidly diagnose problems with the Deposition Controller's
measurement system. See
Figure 7-7 .
Figure 7-7 Crystal Sensor Emulator
The Crystal Sensor Emulator may be attached at various points in the
measurement system, from the oscillator to the sensor head. It provides a known
good monitor crystal with known good electrical connections. Using the emulator
and the controller in a systematic manner provides a fast means of isolating
measurement system, cable, or sensor problems. See
Figure 7-8 .
