I have an SMT microstrip fixture which uses TRL inserts from intercontinental microwave. I have a 3.5" disk with coefficients but cant figure out how to upload cal constants into 8753ES. So I referred to manual on TRL error correction to manually insert coeff. Using short reflection, zero distance thru, and Line 1, I entered user defined parameters. Modify standards, assign standard class, label class, label kit, save user kit. 3x. I realize I must be doing something wrong. Can anyone give me some ideas or tell me how to upload from 3.5# disk.
