i have some questions hope someone can answer them, how i can connect a crystal oscillator (like the one in the picture) to an oscilloscope to see its output waveform (i mean what is the circuit diagram require for this task)
**broken link removed**
also how i can connect a crystal oscillator to one input multiplier terminal.
The appears to be a crystal, not an oscillator. You need to add some electronics to the crystal for it to become an oscillator.
To connect any signal to a one input multiplier terminal, you connect it between the terminal and circuit common (gnd). The commons of the two circuits must be tied together.
