. Use the SAMPLE RATE/SCALE knob to adjust the clock frequency
directly, without having to open the Horizontal menu.
You can open the Horizontal menu by pushing the HORIZONTAL MENU
front-panel button. This is the same as pushing SETUP (front)Horizontal
(bottom).
The HORIZONTAL OFFSET knob on the front-panel is available only for the
Quick Editor. Refer to HORIZONTAL OFFSET knob on page 3–94.
This button lets you set the data sample clock rate used to output a waveform.
Sample rates range from 50.000000 kS/s to 2.6000000 GS/s. The sample rate
controls the frequency of the output waveform frequency, which is calculated as
follows:
Fout = Sample Clock Freq
Samples per Cycle
For example, if the clock rate is 100 MS/s and one cycle has 1000 data points,
then the output frequency is 100 kHz. If you change the clock rate to 550 MS/s,
then the output frequency changes to 550 kHz.
Do the following steps to set the instrument sample clock rate:
1. Push SETUP (front)Horizontal (bottom)Clock (side).
2. Set the value using the general purpose knob, numeric keys, or SAMPLE
RATE/SCALE knob. If you use a knob, you can use the a or ' button to
move the cursor to the numeric character you want to change.
The instrument sets the output clock rate to that specified by the most recently-
loaded waveform or pattern file. In the case of sequence files, the clock rate
defined in the first waveform loaded into the instrument sets the instrument clock
rate. Changing the instrument output clock rate from the front-panel controls
changes the active waveform output frequency but does not change the clock rate
stored with that waveform file.
The instrument also outputs the internal clock signal to the rear panel 1/4
CLOCK OUT connector. Table 3–4 describes the 1/4 CLOCK OUT signal
timing as it relates to the active Run Mode.
