Congratulations - you have now created an arbitrary
waveform.
Setting the Repetition Rate
The next step is to set up the repetition frequency.
Press the FREQ key.
This time, the display shows the frequency of the arbitrary
waveform, initially in terms of the sample rate. Set this to
1 MHz:

The solid diamonds indicate that the display is in fact the
sample frequency.
You can select period, which will change the display to
the sample period (1.000 µs), and you can select
waveform, which will change the display to show the
waveform repetition period (100.0 µs). If you then select
freq again you will see the waveform repetition
frequency, 10 kHz.
You might wish to experiment with the wave insert...
function to see how arbitrary waveforms can be built from
sine waves and other shapes.
