2 Displaying Data
40 Agilent 1000B Series Oscilloscopes User’s Guide
When the time/div is set to 50 ms/div or slower, the oscilloscope enters
Slow Scan mode (see “Slow Scan Mode” below).
When the horizontal scale is set to 20 ns or faster, the oscilloscope uses
sine(x)/x interpolation to expand the horizontal time base.
• Push the horizontal scale knob to toggle between the zoomed time base
and the normal time base display (see “To display the zoomed time
base” on page 41).
The time/div setting is displayed in the status bar at the top left of the
screen. Because all channels are displayed in the same time base (except
in the Alternate trigger mode), the oscilloscope displays one time/div
setting for all channels.
Slow Scan Mode
When the horizontal scale is set to 50 ms/div or slower, the oscilloscope
enters Slow Scan mode.
In the Slow Scan mode, peak detect acquisition is used so that no data is
missed (even the though the Acquire menu may show a different
acquisition mode setting). The oscilloscope acquires sufficient data for the
pre- trigger part of the display, then waits for the trigger. When the trigger
occurs, the oscilloscope continues to capture data for the post- trigger part
of the display.
When using the Slow Scan mode to view low frequency signals, the
channel coupling should be set to “DC”.
The Slow Scan mode lets you see dynamic changes (like the adjustment of
a potentiometer) on low frequency waveforms. For example, Slow Scan
mode is often used in applications like transducer monitoring and power
supply testing.
To adjust the horizontal position
• Turn the horizontal position knob to change the position of the trigger
point relative to the center of the screen.
The position knob adjusts the horizontal position of all channels, math
functions, and reference waveforms.
