Channel toolbar

Hardware instruments have settings that are divided into two groups: Instrument settings, that affect all channels of the instrument and Channel settings, which only influence a specific channel.

The instrument(s) opened by the Multi Channel oscilloscope software can be controlled in different ways. The most convenient way is to control the instruments and their channels by means of the toolbars, shown at the top of the main window.

Instruments and channels can also be controlled by means of popup menus and many settings are also accessible through hotkeys.

This page describes the channel toolbar. For configuring the instrument, visit the page about the Instrument toolbars.

Using the channel toolbar

A channel toolbar is created for each instrument channel. This convenient toolbar has large, clear, touchscreen friendly buttons for all channel settings, such as input range and coupling. It shows the current settings of the channel and allows to change all settings by clicking on the buttons.

The instrument toolbar is fully configurable through the program settings. You can set the button size, add or remove buttons and change the order of the buttons.

Channel toolbar

In the default setup, the instrument toolbar contains the following items:

Channel identification

Channel ID The channel ID displays the channel number and an icon resembling the input type (BNC or banana). Clicking the Channel ID of a channel that is not yet used in the active graph, will add the channel to the active graph. Clicking the Channel ID of a channel that is used in the active graph, will remove the channel from the active graph. Dragging the Channel ID to a graph and drop it there will add that channel to that graph. Right clicking the channel ID will show a popup menu with all channel settings.

Input coupling button

Coupling button The input coupling button allows to toggle between AC and DC input coupling. The image on the button reflects the current state of the input coupling. Hotkeys A and D can also be used to change the input coupling of a channel.

Auto ranging button

Auto ranging button The auto ranging button switches auto ranging of the input on and off. The image on the button reflects the current state of the auto ranging status. Hotkey R can also be used to toggle the auto ranging of a channel.

Increase/decrease input range

Two buttons are available to increase or decrease the input range:

  • Decrease input range Decrease the input range one step (hotkey F5).
  • Increase input range Increase the input range one step (hotkey F6).

The steps that are taken are the input ranges that are available in the input range menu of the instrument channel.

These buttons are particularly useful on touchscreens.

Input range indicator

Input range indicator This item displays the channel full scale input range. Right clicking the Input range indicator will show a popup menu with all full scale input range settings. Hotkeys F5 and F6 can also be used to change the input range of a channel.

Bandwidth limit

Bandwidth limit The Bandwidth limit button allows to select a bandwidth limit for a channel, or to switch it off (full bandwidth). Clicking it opens a menu with available bandwidth limiter settings.

For instruments without adjustable bandwidth limit, the bandwidth limit button is not available.

SafeGround

The SafeGround button allows to select the state of the input channel:

  • SafeGround active Input is switched to single ended, SafeGround protection is active
  • SafeGround inactive Input is switched to differential, SafeGround protection is inactive

For instruments without SafeGround, the SafeGround button is not available.

Probe

Probe readout The probe readout shows the current probe gain setting of a channel. Clicking it opens a menu with available probe gain settings.

Channel invert

Invert button This button inverts the channel by setting the probe gain to -1.

Other controls that can be placed on the channel toolbar are:

Input coupling AC DC buttons

Two buttons are available to set the input coupling to a specific state:

  • Coupling AC button Set the input coupling of the channel to AC (hotkey A).
  • Coupling DC button Set the input coupling of the channel to DC (hotkey D).

Input range up/down

Input range Up/Down With the input range up/down the required input range of a channel is set. Hotkeys F5 and F6 can also be used to change the input range of a channel.

Input range selector

Input range selector With the input range selector the required full scale input range of a channel is set. Hotkeys F5 and F6 can also be used to change the input range of a channel.

V/div input range indicator

V/div input range indicator This item displays the channel input range as a V/div value.

Increase/decrease trigger level

Two buttons are available to increase or decrease the trigger level for a channel:

  • Decrease trigger level Decrease the trigger level one step (hotkey F7).
  • Increase trigger level Increase the trigger level one step (hotkey F8).

The steps that are taken are 2.5%, where 100% equals the full range between +full scale and -full scale. 50% equals 0 V.

These buttons are particularly useful on touchscreens.

Increase/decrease trigger hysteresis

Two buttons are available to increase or decrease the trigger hysteresis for a channel:

  • Decrease trigger hysteresis Decrease the trigger hysteresis one step (hotkey [).
  • Increase trigger hysteresis Increase the trigger hysteresis one step (hotkey ]).

The steps that are taken are 2.5%, where 100% equals the full range between +full scale and -full scale. One division equals 12.5%.

These buttons are particularly useful on touchscreens.

Trigger source on button

Trigger source on button The trigger source on button sets the trigger source of the instrument to this channel.

Create voltmeter button

Create voltmeter button The create voltmeter button creates a voltmeter display for this channel.

Disconnect all sinks button

Disconnect all sinks button The disconnect all sinks button disconnects all sinks from this channel.

Real-time SureConnect connection test indicator

The image on this button reflects the current state of the real-time SureConnect connection test for a channel:

  • SureConnect connection connection
  • SureConnect no connection no connection

It requires real-time SureConnect connection test to be enabled.

For instruments without SureConnect, the SureConnect connection test indicator is not available.
