Parameters
The Parameters group contains three parameters: Amplitude,
Offset, and Segment. The amplitude and offset values displayed in
this group are the same as in the Main Panel. Whenever you
change amplitude or offset in the Parameters group, the Main panel
is updated automatically. The Segment parameter provides access
to the active segment for each channel.
To access the required parameter, click on the parameter name.
The indicator next to the required parameter is then highlighted.
The digital display shows the value associated with the highlighted

10MHz Ref
The 10 MHz group contains buttons that select the source of the
10 MHz reference for standard waveform. The 10 MHz clock is the
reference that feeds the sample clock and the DDS clock, and
therefore determines accuracy and stability. The internal 10 MHz
source has 1 PPM stability over the operating temperature range,
and time stability of 1 PPM per year. The accuracy of the internal
source is adjustable, but will shift with time and ambient
temperature.
When better accuracy or stability is required, or when clock
synchronization to other devices is necessary, you may select
another source. The 10 MHz source options are:
•
Internal: from the built in source
