Horizontal Controls

Press Knob

to toggle between
zero delay and new
setting.

Light On

Indicates that the
vertical controls will

Press to turn on
zoom traces in
a separate grid.

Setup

Press to access
the Timebase
Setup menu.

If All Channel Lights are Off

Then the horizontal and vertical controls are “active” for a Math trace
or zoom trace. If the Zoom light is on then the horizontal controls will
adjust the zoom trace. If the Math light is on both the horizontal and
vertical controls will adjust the Math trace.

status bar directly below the waveform grid.

Vertical cursor information is located
in the trace descriptor.

When Time & Amplitude cursors
are used the readout is displayed
for both cursor types.

button to access the Measure
menu and turn the measurement
parameters on. Press it again to
turn the parameters off.

Up to 4 measurements can be

screen capture to a USB memory device.

Set user preferences in the Utilities menu to
select file type, file name, and background
color.

Press the front panel Save/Recall button to access the
Save/Recall Menu.

In this menu save waveforms to USB memory in either
ASCII or binary formats, and save and recall setup files
from internal memory or from USB memory.

The Save/Recall menu is where the selection to recall the
Default Setup is located.

The rear panel USB port allows for printing
screen captures and can also be used for
remote control from a computer.

Using Replay

Stop the trigger, then press the Intensity knob to
turn on Replay mode; the light will turn on.

Once in Replay, rotate the knob to look back at the
history of acquisitions to isolate runts, glitches, or
other abnormalities.

The display shows a runt pulse along
with a lot of variation in overshoot and
undershoot.

Activate Replay to view each acquisition
individually on the display.

Up to 1024 acquisitions can be viewed
with Replay.

Rotate the knob to scroll through each
acquisition.
