The Horizontal Menu
The Horizontal menu lets you set waveform (analog and markers) horizontal
parameters for all output channels. The horizontal parameters include sample clock
source (internal or external) and clock frequency. The Horizontal menu commands
are Clock and Clock Ref.
The instrument uses only one clock sample frequency rate for all output signals,
regardless of individual waveform settings.
Clock
This button lets you set the data sample clock rate used to output a waveform.
Sample rates range from 50.000000 kS/s to 4.2000000 GS/s (50.000000 kS/s to
4.0000000 GS/s :AWG710). (The sample rate controls the frequency of the output
waveform frequency, which is calculated as follows:
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.
When you load the 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.
NOTE. 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 3-102.
