Instrument 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 instrument toolbar. For configuring the channels, visit the page about the Channel toolbar.

Using the instrument toolbar

An instrument toolbar is created for each detected instrument. This convenient toolbar has large, clear, touchscreen friendly buttons for all instrument settings. It shows the current settings of the instrument and allows to change all settings.

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.

Instrument toolbar

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

Start/Stop button

  • Start button The Start button is used to start continuous measurements.
  • Stop button When the measurement is running, it will change into a Stop button to stop the running measurement.

Both actions can also be executed by hotkey S.

One shot button

OneShot button When no measurement is running, the One shot button is enabled. It can be used start a single shot measurement (hotkey O).

Increase/decrease oscilloscope time/div

Two buttons are available to increase or decrease the oscilloscope time/div:

  • Decrease time/div Decrease the time/div one step (hotkey Ctrl + F11).
  • Increase time/div Increase the time/div one step (hotkey Ctrl + F12).

The steps that are taken are the time/div settings that are available in the time/div menu.

These buttons are particularly useful on touchscreens.

Oscilloscope time/div

Time per div The oscilloscope time/div readout shows the current time/div setting as if the instrument is used as oscilloscope. Clicking the readout shows a popup menu with available time/div settings.

Sample frequency

Sample Frequency The sample frequency readout shows the current sampling frequency. Clicking the readout shows a popup menu with available sample frequencies.

Record length

Record length The record length readout shows the current record length. Clicking the readout shows a popup menu with available record lengths.

Increase/decrease pre samples percentage

The total record can be divided in a part before the trigger moment (pre trigger) and a part after the trigger moment (post trigger). The pre trigger part is set as percentage of the total record. Two buttons are available to increase or decrease the pre samples percentage:

  • Decrease presamples Decrease the pre samples percentage with 5% (hotkey Shift + )
  • Increase presamples Increase the pre samples percentage with 5% (hotkey Shift + )

These buttons are particularly useful on touchscreens.

Pre trigger percentage

Pre trigger The pre samples percentage readout shows the current pre samples setting. Clicking the readout shows a popup menu with available pre samples percentages.

Trigger source

Trigger source The trigger source readout shows the currently set trigger source. Clicking the readout shows a popup menu with available trigger sources.

Trigger settings

Trigger settings The trigger settings button opens the trigger settings dialog, that allows to set all trigger related settings of the instrument.

SureConnect connection test window

SureConnect connection test window When using an instrument that supports SureConnect connection test, this button will be available. Clicking it shows a connection status window with an indicator for each channel (hotkey C).

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

Auto setup button

AutoSetup button The Auto setup button can be used to let the software quickly change several instrument settings, to acquire stable measurements. Use it by clicking the button or pressing its hotkey Q (quick auto setup). When the Ctrl key is pressed while starting the auto setup, the instrument will stay in auto setup mode. This can be used to track changing signals. Choose which instrument settings may be changed by auto setup in Settings→Instruments→Auto setup.

Measure mode button

The measure mode button can be used to switch between:

  • Measure mode button the instrument is measuring in block mode
  • Measure mode button the instrument is measuring in streaming mode

Switching the measure mode requires the instrument to be stopped measuring.

Increase/decrease sampling frequency

Two buttons are available to increase or decrease the sample frequency:

  • Decrease sample frequency Decrease the sample frequency one step (hotkey F3).
  • Increase sample frequency Increase the sample frequency one step (hotkey F4).

The steps that are taken are the sample frequencies that are available in the sample frequency menu of the instrument. When a user defined sample frequency was selected, each subsequent click on one of these buttons will double or halve the sample frequency.

These buttons are particularly useful on touchscreens.

Increase/decrease record length

Two buttons are available to increase or decrease the record length:

  • Decrease record length Decrease the record length one step (hotkey F11).
  • Increase record length Increase the record length one step (hotkey F12).

The steps that are taken are the record lengths that are available in the record length menu of the instrument. When a user defined record length was selected, each subsequent click on one of these buttons will double or half the record length.

These buttons are particularly useful on touchscreens.

Increase/decrease oscilloscope time resolution

Two buttons are available to increase or decrease the oscilloscope time resolution:

  • Decrease time resolution Decrease the time resolution one step.
  • Increase time resolution Increase the time/div one step.

An oscilloscope measurement has a record length and a sample frequency. This gives a total measuring time. With each subsequent click on one of these buttons, the record length and sample frequency are respectively halved or doubled. The total measuring time remains equal, but the time resolution will decrease or increase.

These buttons are particularly useful on touchscreens.

Instrument identification

Instrument ID This item displays the instrument name as well as its serial number, which is a unique number in your measuring instrument. By using the serial numbers as the instrument ID, it is clear which of the instruments you are controlling. Clicking the instrument ID will show a popup menu with all instrument settings.

Record length + Sample frequency + Resolution

RecLen-SamplFreq-Resolution In this item, information concerning the current sample frequency, record length and the resolution is shown. Settings can be adjusted through popup menus by clicking on the text labels.

Time base

Time base The time base readout shows the current settings for the sample frequency and record length, that form the current time/div setting. Clicking the readout shows a popup menu that allows to set the sample frequency, the record length and the total measuring time.

Time out + Trigger source

Timeout + Trigger source When using an instrument that supports triggering, the trigger time out and trigger source of the measuring instrument are also shown. Settings can be adjusted through popup menus by clicking on the text labels.

Presamples knob

Presamples knob The pre samples turning knob controls the pre and post samples ratio. By default, no pre samples are used and it is set to 0%. Dragging it up and down adjusts the knob, a hovering readout displays the current setting. Right clicking it shows a popup menu with predefined settings and a user defined setting.

Resolution
