Horizontal/Acquisition Menu
Use the Horizontal/Acquisition menu options to set the horizontal and acquisition parameters for
waveforms. This menu also provides access to the Zoom controls, Autoset, FastFrame, and Fast
Acquisitions.
Horizontal/Acquisition Setup Control Window
(Horizontal Tab)
Access this control window from the Horiz/Acq menu Horizontal/Acquisition Setup command, or the
Horiz toolbar button.
Overview
Use the Horizontal/Acquisition Setup control window to set the horizontal and acquisition
parameters of waveforms. The horizontal and acquisition controls are common to all channels.
The Horizontal tab controls manage the horizontal setups such as scale and position. Normally, the
horizontal axis displays time information. However, in some cases, the horizontal axis can
represent frequency rather than time.
Record Length
To Use
Click Rec Length to map it to one of the multipurpose knobs and use the
knob to change the record length. You can also use the
increment/decrement buttons beneath the control, or the pop-up keypad.
The record length specifies the number of sample points that make up the
waveform record.
Behavior
The maximum record length depends on the following:
 The amount of memory
 The ability to combine the memory length of unused channels
 The number of frames selected in FastFrame mode
