uW_AMCAD_CST_deembedding - Load-pull measurement de-embedding .
This function read a CST file and de-embed each RF measured wave according the two S2P file located before and after the DUT.
// Split the Test-fixture in two equal parts
// 1. Get the Thru line
filename=tk_getfile("*.s2p");
S_thru=uW_S2P_read(filename);
// 2. Get the Opens
filename=tk_getfile("*.s2p");
S_opens=uW_S2P_read(filename);
// 3. Split the test-fixture
[Sin,Sout,Gamma_open]=uW_S2P_split(S_thru,S_opens);
// Display the results
xset("window",100);
xname("Open @ DUT ref. plane");
uW_S2P_display(Gamma_open);
xset("window",101);
xname("Input,Output and Total Thru S parameters");
uW_S2P_display(Sin,Sout,S_thru);
// 4. LOAD-PULL De-embedding
// The function remove the effect of Sin (S2P with port 1 is the input of the test-fixture and port 2 is the input of the DUT)
// and Sout (S2P : port 1 is the output of the DUT and port 2 is the output of the test-fixture).
// Then, it generate a new IV-CAD file.
filename1=tk_getfile("*.cst"); // File to read (before de-embedding)
filename2=tk_getfile("*.cst"); // File to write (after de-embedding)
uW_AMCAD_CST_deembedding(filename1,filename2,Sin,Sout);
