4 - 60 HOW TO USE THE INSTRUMENT
DIGITAL DISPLAY VERT MAGNIFY
In the digital mode, the displayed signal can be expanded vertically after it has
been captured. This allows you to look to signal details. Please note that the
magnified representation of the signal has the same resolution as the originally
acquired signal.
- Press the ANALOG key to select the digital mode.
-Press AUTOSET.
- Remove the probe tip from the Probe Adjust output.
- Turn the TRIGGER POSITION control to mid screen (counterclockwise).
- Press the SINGLE key to prepare the scope for a single acquisition.
- Touch the probe tip to the Probe Adjust output.
The scope ’runs’ once and a signal appears on the screen.
- Press the DISPLAY key.
- Press the VERT MAGNIFY softkey to turn it on.
- Turn the TRACK control clockwise.
The signal magnifies a maximum of 32 times. The magnification factor is
displayed in the DISPLAY menu. At the same time the vertical deflection in the
bottom text area reflects the expanded deflection factor.
- Use the TRACK control to adjust VERT MAGNIFY to 8.
Observe that you can observe
the signal in more detail. It has
the same vertical resolution as
when captured. Notice the adc
noise being displayed.
Vertical magnify is very useful
when you want to observe a
signal detail with very high
resolution. You can use it in
combination with the horizontal
MAGNIFY function.
Note: If you want to adjust the displayed position of the magnified trace, you
must enter the Recall menu, and use the
∆
control to make any
adjustments to the Y position.
