3) Conditions
1. Oscilloscope: Impedance Min. 1MΩ
Input capacitance Max. 10 pF
Band width Min. 300 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. Load_C includes probe capacitance.
3. A capacitor (By-pass:0.01 to 0.1 μF) is placed between Vcc and GND,and closely to TCXO.
4. Use the current meter whose internal impedance value is small.
5. Power Supply
Impedance of power supply should be as low as possible.
6. GND pin should be connected to low impedance GND.

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