Figure 3.9 Adjusting Parameters of standard signals

Changing the

Frequency and

Sample Clock

The user 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. On the other hand, the sample clock frequency

parameter is valid for arbitrary 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 Sa/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 the specifics of the waveform defined

Use the following command to change the frequency for standard

waveforms:

FREQuency {<frequency> | MINimum | MAXimum}

MIN selects the lowest frequency allowed for the currently active

function. MAX selects the highest frequency allowed for the currently

active function. The default frequency setting is 1 MHz for all

parameters.
