Using the Instrument
Generating Sequenced Waveforms
3-41
Alternately, after you display the edit field, you may use the dial
and/or the arrow keys to modify the field then, press Enter to lock in
the new value. If you did not make programming errors and did not
make any mistake while downloading your waveform segment(s),
then the output should generate your desired waveform. There are
seven parameters that are available for programming in this
window:
View Table
– Provides access to a sequence table. If no table was
yet defined, you can define the sequence table from this menu. You
can also edit an existing sequence table from this command.
Information on editing the sequence table is given later.
Advance Mode
– Defines the advance mode for the sequence.
There are four advance mode options you can select from:
Automatic, Stepped, Single and Mixed. A description of the various
advance modes is given later. Note that advance mode depends on
run mode and therefore, if you selected continuous run mode for
the 2074, you will not see the Single advance mode in the advance
mode options list. Similarly, if you selected triggered run mode,
Stepped and Mixed will be omitted from the list.
Advance Source
– Defines which of the triggers inputs will
advance the sequence. The advance source has no effect on
Automatic advance source.
Sample Clock
– Programs the sample clock frequency for the
sequenced waveform. The final period of the complete sequence
can be extracted from the following relationship:
Sequence Duration = 1 / (SCLK / n)
n = the number of waveform points in the sequence, including
looped waveforms.
Amplitude
– Defines the amplitude of the sequenced waveform.
Offset
– Defines the offset of the sequenced waveform.
Active segment
– Programs the active segment in a sequence.
The SYNC will be placed on the active segment. There is no other
purpose for this parameter in the sequence.
Tip
Use the arrow keys or the dial to scroll through the
sequence parameters. The View Table will remain at the
top while the others may be accessed selectively.
