Hello friends,
I am trying to measure s-parameter of N-path filter with LSSP.  I found there are two ways to use it
1. via hb analysis
2. Tools-RF-LSSP.https://filebox.ece.vt.edu/~symort/rfworkshop/Mixer_workshop_instruction.pdf
I tried the second method and results is little off. I couldnot find any document related to method one. please help me with that.
Or guide me to use LSSP.
