Hi, i'm designing an impedance tuner for source pull measurements between 200-600MHz. For this I build different matching networks to transform the 50ohm of my noise source to different impedances which I then connect to the dut(LNA) as shown in the picture below. However as expected the impedance between the tuner and noise source is not matched(as expected). I believe this is will not impact my measurements as the noise source is screwed onto the tuner and the frequency is quite low. Is that correct and if no?
