Translate Smith-Chart statement to English?
I recently bought an automatic tuner (I know, I know; I wasted my
money since manual tuners are so easy to build) which could supposedly tune "8-1000" ohms resistance. I first asked the manufacturer if maybe they meant "impedance", and they replied "Yes, thanks for the correction". That lead to a followup question: ( NOTE: My keyboard doesn't have keys for "plus or minus" or "square root" so I'll use "#" and "SQRT()", respectively.) "Does '8-1000 ohms impedance' include ALL COMBINATIONS of #X#jY SUCH THAT SQRT (Xsquare + Ysquare) is in the range of 8 to 1000 (such as #8+j0 to #1000+j0 and 0#j8 to 0#j1000), or are there some "holes" in coverage?" Their response was: " We use the polar coordinate system and it covers all phase angles at 14 MHz. Obviously, plotted on a smith chart you would see the range decrease as you depart from 14 MHz." I haven't used a Smith Chart since I was first introduced to them in college (1963!-() Could someone please translate their response to simple English that I can understand. In particular, what range of impedances might their tuner cover on 80 meters? 40 meters? 15 meters? 10 meters? |
