3) Condition
1. Oscilloscope :Impedance
Min. 1 MW
Input capacitance
Max. 15 pF
Band width
Min. 400 MHz
Impossible to measure both frequency and wave form at the same time.
(In case of using oscilloscope's amplifier output, possible to measure both at the same time.)
2. CL includes probe capacitance.
3. By-pass capacitor (0.01 mF to 0.1 mF) is placed closely between VDD and GND.
4. Use the current meter whose internal impedance value is small.
5. Power Supply
½Start
up time (0 %VDD→90 %VDD) of power source should be more than 150 ms.
½Impedance
of power supply should be as lowest as possible.
6. One point earth of test cirouit is required.

To maintain stable operation, provide a 0.01uF to 0.1uF
by-pass capacitor at a location as near as possible to the
power source terminal of the crystal product (between Vcc
- GND).
