15. Read the waveform frequency. Confirm if the both mean frequencies (write+ and
write−) are 10 MHz ± 100 Hz.
16. Click
Abort to stop the data pattern.
17. Click
Return > Return > Config to return to the configuration page and turn off the
output signal.
18. If the waveform is not observed, check the cable connection. Especially, clean the
E5029K connection board and the connection pads on it.
Step 2. Clock Signal Test at E5037C/D
If the cable connection is OK but the waveform is not observed properly in Step 1, check
the signal on the E5037C/D in accordance to the following procedure.
1. Connect the cables between the ‘Clock Pos’ and ‘Clock Neg’ on the E5037C/D and the
channels 1 and 2 on the oscilloscope.
These connections are shown in Figure 2-21.
