			The RG-214 cable I ordered from Germany to make up some patch leads 
		
		
		
		
		
		
		
		
	
	for my VNA has finally arrived. It was advertised as "high-end audio cable" which is what it's commonly sold as over there (those wacky Germans!) but it *is* the real deal low-loss 50 ohm UHF cable, nevertheless (just as well since it took 3 months to arrive). Now I have to make up these leads with N-type connectors to replace the stock leads that didn't come with the analyzer. These hook up the VNA to the Transmission/Reflection Test Set (which I do have). I see from HP's tech spec that the interconnects I need to copy comprise what was originally sold as the "11851A RF cable kit" and it consists of four cables. Now here's the tricky bit: "Kit includes three 24" 50 ohm cables, phase-matched to 4 degrees @ 1300Mhz and one 34" cable. The 34" cable is used to phase balance the transmission path of the Transmission/Reflection Test Set." So does this mean the cable lengths are critical and if so, how best to go about making them up? thanks, p. -- "What is now proved was once only imagin'd" - William Blake  |
