on Aug 1, 2018I am trying to understand how to use a variable as an index in a measurement expression for use with the data display.
According to the help article on Measurement Expressions, I am trying to use an output variable as the expression list for a sweep index operator.
I have attached an archive of a simple example workspace in ADS 2017 demonstrating the problem (see also the screen capture of schematic and data display). The expression dBm(vout[::,idx]) in the data display window is flagged as invalid even though dB(vout[::,1]), dB(vout[::,2]) and idx are all valid expressions and idx takes on the values 1 and 2.
If the problem is with syntax, I would like to know the correct syntax to perform this operation. If there is an architectural reason why this doesn't work I would like to know why and if there are suggestions for an alternative approach to achieve the same result.
Hi,
the value of idx is probably 1.0 and 2.0 though smart formating doesn't unveil this. Use a what(idx) inside a table display and you can inspect the storage type: real. I'd bet int(idx) is going to solve your problem.
