Field or control Description
Minimum Sample Rate Sets the minimum sample rate for acquisitions. Changing horizontal scale will not reduce the sample
rate below this value. This can result in partial waveform records at lower frequencies, but at the same
time would provide more sample points for a few cycles of the signal.
A
vailable when Horizontal Mode is Automatic.
This setting can be overridden if Allow Horizontal Scale to Override Min Sample Rate is selected.
Allow Horizontal Scale to
Override Min Sample Rate
Select to set the oscilloscope to automatically change the sample rate to acquire a full waveform
record. Changes to the sample rate are shown in the Horizontal badge readout, not in the Minimum
Sample rate field of the menu.
Available when Horizontal Mode is Automatic.
Horizontal Scale Tap to set the Horizontal Scale using the assigned multipurpose knob, double-tap to set the scale
using the virtual keypad, or tap the up and down arrows. You can also use the front-panel Horizontal
Scale knob to change this value.
The horizontal scale determines the size of the acquisition window relative to the waveform. You can
scale the window to contain a single waveform edge, a single cycle, several cycles, or thousands of
cycles.
Delay Delay positions the trigger event to a specified time relative to the center of the waveform record. Use
delay to focus on events that occur before (pre-trigger) or after the trigger point (post-trigger).
Position Tap to set the trigger Position using the assigned multipurpose knob or double-tap to set the Position
using the virtual keypad.
When horizontal Delay is on, the time from the trigger point to the horizontal reference (center of
waveform record) is the horizontal delay. The horizontal position determines the number of pre-trigger
and post-trigger samples in the waveform record.
When horizontal delay is off, the trigger point and the horizontal reference are at the same time in the
middle of the waveform record.
Set to 0 s Tap to set the delay position to 0 s (center of the waveform record.
Available only when Delay is On.
Set to 10% Tap to set the trigger delay to 10% of the waveform record.
Available only when Delay is Off.
Sample Rate Changes Affect Tap to allow changes to the Sample Rate to affect either the Horizontal Scale or the Record Length.
Available only when Horizontal Mode is Manual.
Sample Rate Tap to set the Sample Rate using the assigned multipurpose knob, double-tap to set the rate using the
virtual keypad, or tap the up and down arrows. This keeps the oscilloscope at the specified sample rate
regardless of the horizontal or record length settings. This limits the available horizontal scale settings
to those that can be used with the specified sample rate.
Available only when Horizontal Mode is Manual.
Record Length Tap to set the Record Length using the assigned multipurpose knob, double-tap to set the length using
the virtual keypad, or tap the up and down arrows.
Available only when Horizontal Mode is Manual.
