Hello HP guru's. I bought a HP 8620A sweep generator with the plugin 86222B and the 86250D The 86222B goes from 0.01 to 2.4 GHz and the 86250D from 8 - 12.4 ...

Hi Geoff & Elie, Many thanks for your replies. I had a thought that the crt might be u/s and you have both confirmed it. Thanks Elie for your info re low gain,...

Thanks, David! I've made the change. Someone goofed and put the installation note at the front of this PDF -that must have confused the web entry team. I...

does anyone know how to measure the impedance of long wire antennas using an HP-608A oscillator and a HP410C voltmeter or some other simple methode. David...
Hello Mitch, Sorry, I but I havn't fixed it yet. I've got the manual and schematic, and as I'm not familiar with elaborate scopes ( even those built 30 years...
... The problem is that antenna impedance (indeed impedance in general) is a complex quantity R + jX (or G + jB), so it is very difficult to measure using a...

Dave, That's helpful. But it doesn't contain any schematics, just the calibration and alignment sections. Is there another number I should be using to get the...

no it was different and was made to measure long wires without a receiver, had a built in oscillator and used a seperate analog vom that would dip, sort of a...
Craig: I have a similar question and I'd love to have a real answer to it. I have an HP 8754A network analyzer that is both scalar and vector, and I have both...
... Well, you could do a calibration using shorts, opens, etc out at the end of the coax (by the antenna), and then read the impedance of the antenna directly....
Chuck: Ok, I have the 8754A books, but I don't have a calibration kit or the manual for it. Let's suppose I do have a calibration kit with std. open and short ...
I have also pondered the feasibily of making antenna measurements with a network analyzer. In fact I know it is done quite often although I don't have a lot of...
... Well, in that case, you can't measure the exact impedance at the antenna. In the ideal case, the coax is going to introduce two things: the first is ...
... Well, measuring diverse impedances *is* what a network analyzer is all about. Calibration is a method of measuring the imperfections in the various parts...
Chuck: The application of measuring an antenna at the end of a 500' feed line is to avoid climbing the tower if the antenna is good. And sometimes, we don't...
Gary, ... The vector measurement is not a good choice for this. Even if you climb up and calibrate at the antenna end of the cable, you would need a similarly...
