7.6.3 Setting Clock Rate and Divide Rate
The bit rate can be set by measuring the clock rate from the signal input
to the Trigger Clk In connector of the front panel.
1. Touch [Time].
2. Touch the Tracking button of the Data Clock Rate to set to [Off].
3. Touch the Recalculate Option button to select [Bit Rate].
4. Touch [Acquire Clock Rate].
The frequency is displayed in the Clock Rate text box.
Confirm the waveform and signal level input to the Trigger Clk In
connector when the frequency is not displayed.
5. When the clock frequency is not displayed at Clock Rate or the
displayed frequency is not correct, touch the Clock Rate text box and
input the frequency.
6. Touch the Divide Rate text box and input the divide rate.
The bit rate is calculated by the divide rate and clock rate.
When using the BERTWave Sync Out as an external clock, the divide rate
is set as follows.
