Note
The picture in the 2074 LCD display is an icon only. The
actual output waveform may look entirely different.
Changing the
Output Frequency
You should be careful not to confuse waveform frequency with
sample clock frequency. The waveform frequency parameter is
valid for standard waveforms only and controls waveform frequency
at the output connector; The sample clock frequency parameter is
valid for arbitrary and sequenced waveforms only and defines the
frequency of which the generator clocks data points.
Standard waveform frequency is measured in units of Hz. Arbitrary
waveform sample clock frequency is measured in units of S/s
(samples per second). The frequency of a given arbitrary waveform
at the output connector is dependant on sample clock frequency,
the number of data points, and other specific waveform definitions.

Figure 3-5, Modifying Output Frequency
The frequency of the output waveform will change only if a standard
waveform is generated. First select a standard waveform as
described earlier and then proceed with frequency modification.
Observe Figure 3-5 and modify frequency using the following
procedure. The index numbers in Figure 3-5 correspond to the
procedure steps in the following description.
1. Press the Frequency soft key to select the frequency parameter
2. Use the numeric keypad to program the new frequency value
