Parameters for ES930: Analog Channels Tab

Shows a consecutive number for each entry in the hardware configuration table.

You cannot edit this field.

Use this checkbox to enable or disable this signal for further configuration steps.

Disabled signals will not be available in the Experiment Environment.

You can also use the context menu commands Enable All Channels and Disable All Channels to enable or disable all channels at once that are displayed on the selected tab.

Shows the name of the measurement variable assigned to this channel. The name can be edited. It must be unique for the whole configuration.

Enter the unit according to the signal to be measured.

The selected unit appears in the corresponding measure windows.

Defines the default acquisition rate necessary for your measurement task.

The acquisition rate can be selected separately for each channel of a device. It is used as default rate within the measuring environment (e.g. INCA Experiment Environment), but you can overwrite it (e.g. in INCA's Configure Variables dialog).

Enables or disables the internal hardware anti-aliasing filter.

When the filter is turned off, the field turns red to indicate that aliasing effects might occur, i.e. that signals can be distorted. Disable the AA filter only if an external low pass filter is used instead.

Defines whether the digital filter is switched on or off.

When the digital filter is turned off, the field turns red to indicate that aliasing effects might occur, i.e. that signals can be distorted. In the Filter Frequency column the string --- is displayed to indicate that no filter frequency is selected.

Defines the -3 dB cutoff frequency of the digital filter for the signal conditioning of the channel. Which settings are possible depends on the current acquisition rate.

You can either manually select the desired corner frequency or select FIR Auto for the Filter Frequency:

• FIR Auto (recommended):

  The software calculates the corner frequency as follows:

  fc=0.4*fS,SW

  where fc: corner frequency, fS,SW: sampling rate as selected in the Rate field of the configuration software

Enter the lower physical value according to the sensor used.

You can find this value in the datasheet of your sensor.

Enter the upper physical value according to the sensor used.

You can find this value in the datasheet of your sensor.

Enter the value of the lower sensor signal according to the lower physical value.

Enter the value of the upper sensor signal according to the upper physical value.

When you click into this field, an editor opens where you can create special conversion formulae.

Enter the lower limit of the expected physical measurement range.

This value is used together with the values of the Phys bottom, Sensor bottom and Formula parameters to calculate the amplification factor.

The highest amplification factor possible is selected to ensure that none of the connected channels is overloaded.

Enter the upper limit of the expected physical measurement range.

This value is used together with the values of the Phys top, Sensor top and Formula parameters to calculate the amplification factor.

The highest amplification factor possible is selected to ensure that none of the connected channels is overloaded.

Shows the lower physical limit of the measurement range actually possible for this channel.

This value is determined by the values of the Phys bottom, Sensor bottom and Formula parameters as well as by the actual measurement range of the module.

You cannot edit this field.

Shows the upper physical limit of the measurement range actually possible for this channel.

This value is determined by the values of the Phys top, Sensor top and Formula parameters as well as by the actual measurement range of the module.

You cannot edit this field.

Enter any comment for that signal. The comment may be displayed along with the signal in some dialogs in the rapid prototyping or measurement and calibration tool used.
