Channels[edit]

AD convertors can have multiple channels on which AD values could be read. For each AD channel, different commands can be set.

Trigger and Reading[edit]

  1. A trigger command can be specified to request a measurement from the device.
  2. A regular expression can be set to parse 1 numeric value from the returned message of the device. The parsed number will be used in RadiMation
ScreenElementDescription.svg Trigger and Readback

The trigger and read back commands are used to receive the measured values into RadiMation

ScreenElementDescription.svg Trigger The command need to trigger the measurement. A common used SCPI is *TRG. When left blank no command will be send.
ScreenElementDescription.svg Read Back In the read back the returned information is defined. This is different for every type of machine there for RadiMation® used regular expressions to understand the format. A good regular expression for finding the first number in scientific notation in a text is:
([+-]?[0-9]*\.?[0-9]+([eE][+-]?[0-9]+)?)

For more possibilities see the example section

Trigger and Reading[edit]

ScreenElementDescription.svg Minimum and maximum value

Minimum and maximum can be set to limit the measured value.

  1. !Minimum value! The minimum on which the measured value will be cut off.
  2. !Maximum value! The maximum on which the measured value will be cut off.
ScreenElementDescription.svg Minimum value The lowest value that can be measured with this device. The value must be the same as filled in the EUT window.
ScreenElementDescription.svg Maximum value The highest value that can be measured with this device. The value must be the same as filled in the EUT window.
