"Well, i am going to write a calibration procedure for directional bridges. More specifically the 85020A/B and 85027A/B/C/D."
"hey Dave, I still have one of those calculators. Its called a reflectometer calculator. You say that the sliding load should be a flush fit. With the 905A sliding load you can ensure a flush fit. But with the 911 series sliding load how do you ensure a flush fit? You extend and connect the center conductor, then screw the nut on, then snap the center conductor in the locked position. You don't know if you have a flush fit or not. We also did 2 directional bridges lately (85020A, 85027C) the way Joel described and we got good results with just using a termination. We did correct the bridge directivity number to account for the terminations rho."
"Say Dave, Could we take this conversation offline. The subject has changed to scalar network analyzer bridges and there are many questions concerning the HP performance tests in the tech manual concerning these bridges that I have. So if you give me your email address so that I could send you a email to continue this conversation. Thanks, Larry H."
"hey Dave, Did you get the private messages I sent to you? If not, then how do you send a private message.. larry"
