HDO6000 High Definition Oscilloscope

Vertical

Vertical, also called Channel, settings usually relate to voltage level and control the trace along the Y axis.

NOTE:While Digital settings can be accessed through the Vertical menu on -MS model oscilloscopes,

they are handled quite differently. See Digital Overview.

The amount of voltage displayed by one vertical division of the grid, or Vertical Scale (V/div), is most

quickly adjusted by using the Front Panel Vertical knob. The Channel descriptor box (Cx) always shows

the current Vertical Scale setting.

More extensive Vertical settings are made on the Channel dialog, which will be labeled Cx after the

corresponding channel. To access the Channel dialog, choose Vertical > Channel <#> Setup from the

menu bar, or touch the Channel descriptor box.

The Channel dialog contains:

l Vertical Controls for vertical scale, offset, coupling, bandwidth, and probe settings.

l Pre-Processing Controls to set up pre-acquisition processes that will affect the waveform, such as

noise filtering and interpolation.

If a probe is connected to the channel, the Channel dialog also contains a tab for the Probe dialog.

Vertical Settings

Vertical Scale - Set the vertical scale or sensitivity, and choose fixed or variable gain adjustment.

Vertical Offset - Select between zero vertical offset or to set the offset to a specific value.

Coupling - Select from DC 50 Ω, DC1M, AC1M and GROUND.

CAUTION. The maximum input voltage depends on the input used. Limits are displayed on the

front of the oscilloscope. Whenever the voltage exceeds this limit, the coupling mode

automatically switches to GROUND. You then have to manually reset the coupling to its

previous state. While the unit does provide this protection, damage can still occur if extreme

voltages are applied.

Bandwidth - Bandwidth filters are available at a variety of fixed bandwidth settings. The exact settings

vary by model.

Probe Attenuation -Enables you to set probe attenuation manually if using a third-party probe. The

oscilloscope's inputs automatically sense Teledyne LeCroy probes and sets probe attenuation and

Vertical units for you.

Vertical Unit Override - Allows the units of the selected channel to be changed from Volts (V) to Amperes

(A). This is useful when using a third party current probe that is not auto-detected or when probing across

a current sense resistor.
