Frequency Divider Board Test Setup
1
Connect CH1 SMA connector to the Device Under Test (DUT).
2
Use BNC to BNC cables to connect both J400 and J403 BNC connectors to
the oscilloscope and the AWG 10 MHz In.
3
Select 4.2 Vpp output voltage by shorting Pin1 and Pin2 of J100 with jumper.
Remark: 10MHz ref input amplitude and frequency specification for every
oscilloscope might be different. Please ensure the oscilloscope that you use
meets the specifications. In the event it doesn't, an attenuator might be
required.
4
Select Normal Running mode by switching switch A1 to OFF.
5
Select Frequency Tracking mode by switching switch A2 to OFF.
