Configurable AD Convertor: Difference between revisions

Revision as of 10:29, 6 October 2016

The Configurable AD Convertor device driver is a AD Converter which is supported by RadiMation^®.

Initialisation and Check[edit]

Reset

The reset code that needs to be send to device. When left blank no command will be send.

Init

The command that is send to initialize the configured device. When left blank no command will be send.

Get Id

The command that is send to retrieve the ID of the device. This is used to check if the device is connected. A common used SCPI command is *IDN?. When left blank no command will be send.

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]

A trigger command can be specified to request a measurement from the device.
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

Trigger

A trigger command can be specified to request a measurement from the device. A common used SCPI is *TRG. When left blank no command will be send.

Read Back

Different devices return different messages with measurement values. The configurable AD converter only need the numeric value of the measurement. There for, a regular expressions can be set in the Read Back.

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

Minimum and maximum value[edit]

Minimum and maximum can be set to limit the measured value. And to calculate the measured value to a specific unit.

Minimum value

The lowest value that can be measured with this device. The value must be the same as filled in the EUT window.

Maximum value

The highest value that can be measured with this device. The value must be the same as filled in the EUT window.

Readback example(s)[edit]

Received information	Regex	RadiMation Readout	Note
U_L_N 325	(-?[0-9.,Ee-]+)	325	Takes the first number.
I_L1;12.34	;(-?[0-9.,Ee-]+)	12.34	Takes the first number after ";".
THD_U_L1;;14,5	;;(-?[0-9.,Ee-]+)	14.5	Takes the first number after ";;".
AC_FREQ;Channel1;1.23E3	;*;(-?[0-9.,Ee-]+)	1230	Takes the first number after the appearance of a second ";".
