Writes or reads out the array of the isolation calibration
measurement performed between the receiver port <rcvport>
and the source port <srcport>.
The array size is 2N, where N is the number of measurement
points.
For the n–th point, where n from 1 to N:
<numeric 2n–1> real part of the measurement
<numeric 2n> imaginary part of the measurement
(command/query)
<rcvport> the number of the receiver port from 1 to 2 (or 4)
<srcport> the number of the source port from 1 to 2 (or 4)
<numeric list> the isolation measurement data array
