Measure frequency from 2pins X-TAL Circuit ( Over 1Mhz X-TAL Device, +5V) Measure frequency from 2pins X-TAL Circuit
( Over 1Mhz X-TAL Device, +5V)
KEY POINTS
1)
CLK Out pin
of X-TAL has to connect
FREQ_IN_A pin
of XTALOS.
2) Frequency Input pins of XTALOS,

Over 1Mhz:

Use single wire wrapping (Un-twist)
3) Frequency Output pin from XTALOS:
Use twist wire wrapping
4) CN1, CN3:
Use single wire. (NO Twist)
5) If input frequency has under 1Mhz,
Insert Jumper JP2
on XTALOS
6) Connect from Test Probe under UUT: CN1, CN3
Connect to ATE Systm (Counter, Short/Open/Analog/XTAL Frequency measure):
CN2
Connect to ATE Systm (Perpin, Short/Open/Analog Test): CN4
7) Check the Power Souces:
If DC Power has over +9V,
Insert J3
and using
J1.1~2 (over +9V),
J1.4~6 (GND)

If DC Power has +5V,
Remove J3
and using
J2.1~J2.3 (+5V),

J1.4~6 (GND)
