Horizontal Position/Scale Control Window: Scale
Delay On
To Use
Click the Scale control to map it to a multipurpose knob and use
the knob to change the scale. You can also use the
increment/decrement buttons beneath the control or the pop-up
keypad.
Behavior
Use the Scale control to adjust the time base. This control scales all live displayed waveforms at
the same time.
When horizontal delay is on, the scale expands or contracts around the horizontal reference point
instead of the trigger point.
The scale units depend on the waveform type. In most cases the horizontal units will be time.
However, the horizontal units can also be frequency.
Use the dedicated front-panel HORIZONTAL SCALE knob to change the horizontal scale.
Resolution Control Window
Access this control window from the Horiz/Acq menu Resolution command.
Overview
Use the Resolution control window to select the number of samples per division for all acquired
waveforms.
To Use
Use the multipurpose knob to adjust the Record Length.
Behavior
The Duration, Sample Rate, and Resolution controls are readouts only.
Their settings are impacted by other controls.
Duration specifies the time across the 10-division screen.
Sample Rate specifies the number of samples per second that will be
acquired for each waveform. The faster the sample rate, the more
accurately the instrument can represent fine details in a fast signal.
Resolution is similar to the acquisition interval. It can be thought of as
the time between sample points. In most cases, the acquisition interval is
the same as the resolution.
Record Length specifies the total number of samples in the waveform
acquisition. The maximum record length depends on the amount of
memory in the instrument.
