The Frequency control lets you program the output frequency of the
selected waveform shape. The frequency parameter may be
modified when the LED illuminates. You can use the dial, keyboard,
or the [

you modify the reading, press Execute to update the 5251 with the
new reading.
Arbitrary/Sequence
The Arbitrary & Sequence panel, as shown in Figure 3-7, is invoked
by pressing the Arb/Seq button on the Panels bar. Note that if you
invoke the Arbitrary & Sequence Panel from the Panels menu, the
5251 will not change its output type. On the other hand, if you select
the arbitrary, or the sequenced options from the Main Panel, the
5251 will immediately change its output to the selected waveform
type. The functional groups in the Arbitrary Waveforms Panel are
described below.
Parameters
The Parameters group contains three parameters: Amplitude,
Offset and Segment. Actually, the amplitude and offset values
exhibited in this group are exactly the same as in the Main Panel,
so every time you change amplitude and offset in the Parameters
group, the other panels are updated automatically. The segment
parameter provides access to the active segment for each channel.
By selecting a segment as active, the sync pulse is attached to this
specific segment number.
To access the required parameter, click on the parameter name.
The LED next to the required parameter turns on. The value that is
associated with the lit LED is displayed on the digital display. You
can use the dial, keyboard, or the [

to the required setting. After you modify the reading, press Execute
to update the 5251 with the new reading.
