De AA-1500 beschikt tevens over een geïntegreerde Time Domain Reflectometer-modus, die helpt bij het opsporen van storingen in het systeem. Dankzij de Bluetooth Low Energy module kan de analyzer draadloos verbinding maken met een PC, laptop, tablet of smartphone. Met de AA-1500 ZOOM analyzer kunnen uiteenlopende antenne- en kabelanalyses worden uitgevoerd, waardoor hij een essentieel instrument is voor zowel radioamateurs als communicatieprofessionals.

    Het controleren van een antenne

    • Een antenne afstemmen op resonantie
    • Vergelijking van kenmerken van een antenne voor en na een specifieke gebeurtenis (regen, orkaan, enz.)
    • Coaxiale stubs* maken of hun parameters meten
    • Kabeltesten en foutlocatie, meten van kabelverlies en karakteristieke impedantie
    • Meten van capaciteit of inductantie van reactieve belastingen

    *In microgolf- en radio frequentietechniek is een stub of resonant stub een stuk kabel of golfgeleider dat slechts aan één uiteinde is aangesloten. Stubs worden vaak gebruikt in circuits voor het afstemmen van antenne-impedanties, frequentieselectieve filters en resonantiecircuits voor UHF-elektronische oscillatoren en RF-versterkers. Een elektronische oscillator is een elektronisch circuit dat een periodiek, oscillerend elektronisch signaal produceert, vaak een sinusgolf of een blokgolf of een driehoeksgolf. Oscillatoren zetten gelijkstroom (DC) van een voeding om in een wisselstroom (AC) signaal.

    Type connector: 
    Vorm uitgangssignaal: vierkant, 0,1 tot 200 MHz. Voor hogere frequenties worden harmonischen van het hoofdsignaal gebruikt.
    Uitgangsvermogen: -10 dBm (bij 50 Ohm belasting)

    Voeding

    Drie 1,2V, 1800…3000 mAh, Ni-MH-batterijen, type AA
    Maximaal 3 uur continu meten, max. 2 dagen in stand-bymodus wanneer volledig opgeladen batterijen worden gebruikt
    Wanneer de analyzer is aangesloten op een PC of een DC-adapter met een USB-aansluiting, krijgt hij stroom van deze bronnen

    Forged Knives at a Stamped-Knife Price
    Size: 18-Piece, Style: Traditional Handle Design
    Purchased as a gift for a friend suffering with an old, rusted, chipped set of cheap big-box knives. As far as I can tell, these are one-piece forged/milled knives with a full tang... no idea how Amazon gets them so cheap. I have a set of J.A. Henckels Four-Star that were 5x the price, and these knives are almost as nice in fitment and quality. Some of the grinds at the bolster aren't quite symmetrical, but nothing that functionally affects the knife. Not show-dogs, just old reliable mutts that get you where you need to be. Knives have a good weight and balance, not too heavy but sit well in the hand and have a nice action. The edge out of the box is only average, and the chef's knife had a decent roll to the edge out of the box. However, they sharpen easily and can take a fine edge with a little work with the steel (no word on edge longevity yet, they don't cook that often). The shears come apart for cleaning (which is nice), although I found it a little too unstable when opening them wide, the rivet is at 90* so when taking a big bite they have a tendency to come apart rather than scissor. Changing to a design that doesn't separate until they're fully open would make them much better. The woodblock is pine, and had a distinct pine scent out of the box (I suppose this is an area where they saved money, I would pay a premium to get a bamboo block instead). The exterior was well-finished, but the interiors of the knife slots did have some rough spots and/or splinters from the milling. Nothing that stops it from working as intended, a little back and forth solved the majority of problems. Friend hand washed them after receiving them, but left them damp. Water spots, but no rust on any of the blades, the steel had light surface rust that came off with a scrubby sponge and soap. Overall I remain optimistic they will stand up to the abuse of a forgetful cook. Having bought expensive German steel, and now these, I daresay I would probably be unable to tell the difference between the two in the kitchen.

    This is an inexpensive quality knife set!
    Size: 18-Piece, Style: Traditional Handle Design, Size: 18-Piece, Style: Traditional Handle Design
    I have been a Chef for 17 yrs. and from experience know you don't get quality in an inexpensive knife set. This AmazonBasics Premium set really impressed me. The knives I use and have at home are mixed matched because I like good hefty knives. My wife always rags on me that the knives look crappy, so I got on here and started reading reviews. I was not gonna spend alot of money on a set knowing that I have good knives already. Then I saw this set, and looked at the video. I got them in TWO days, and when I opened the package I was expecting the block to be split, chipped, or have saw marks. As you can see the one I got was flawless. I then took out the chefs knife and smiled. Easily comparable to a 8" Zwilling JA Henckels Pro Traditional Chefs Knife. It has the same quality, heft, and balance. TRUST ME I KNOW!!!! Beautiful knife. The thickness of the blade is equal to my Victorinox Fibrox Chefs Knife and I paid $45. for that knife alone!!! This here is a quality product at a good price. Treat them with respect and they will last for YEARS. If your looking for a good complete set, a nice wedding gift, of just looking to replace the "crappy" set you have look no further.

    Amazing for the price
    Size: 9-Piece, Style: Traditional Handle Design
    At a higher price they would have been 4 or 3 stars, but for $50 this is an insane deal. The steel is pretty good quality. It almost seems like it's hardened VG-10 but I think they would advertise that if it were so I'm guessing it's a cheaper stainless steel that just comes harder without being treated though I'm just speculating based on price. Anyways they're flat ground, take an edge easily, and hold it reasonably well. Nicer knives would certainly hold an edge longer but I'm pretty happy with them. The flat ground shape of the blade is actually ever so slightly convex as well, it's not too apparent in use but you can certainly see it in the reflection. The serration on the bread knife is the inverse of what I would prefer, rounded metal with points cut into it vs points extending from the blade with the rounded parts cut out. When the rounded parts are cut out it's easy to sharpen. When the points are cut out it's almost impossible to sharpen. The handles are the downfall of the knives. They're not smoothly finished and while they look alright they feel like a cheaply cut (although very solid) piece of plastic which is exactly what they are. A little bit better finishing on the handles would really improve the knives. The holding block serves it's purpose well. The sharpener is ok but below average, though the rough steel rod sharpeners just aren't great to begin with. Diamond coated rods are much better, though ceramic rod sharpeners are the best. Overall I love the knives and I'm glad I bought them. For the price they're the best deal I've ever found, no question. I love that there is no logo on them, but I just don't like to see branding in general even if it's a premium brand. If you're buying this for the bread knife or the sharpener, don't, they're not good. If you want the look and feel of a $300+ knife set, don't buy this, you'll be disappointed. If you want a good quality knife set but aren't willing to spend $300+ then absolutely buy these, they're great.
