eBay My asking price includes 30 days guaranty (longer is available, read..). Offered here is a specimen, serial B064724 with less than 9 thousand hours (equivalent to about 4 years’ use). THE GPIB option, hinted at by 3 LEDs in the screntop label and a rear connector, was removed, and is fairly useless on analog scopes. The Tek 2445B is a well designed 4 channel analog 200MHz bandwidth portable package, made from mid-1988 to mid-1996 that would be useful for decades to come (this one was made in late 1994). Its actual measured bandwidth during cal came out as 260MHz (which is normal and easy because a 2445B is really a bandwidth chocked 400MHz 2465B). Should you want the bandwidth upgrade now, or even at some future date, I will do it for $200 (my price difference between the 2). Costs only a tiny 10% fraction of its $7,000 new price, yet for the foreseeable future, well maintained 2445Bs (last scope series Tek made to be component level repairable) by me, will still be serving their owners well, while many newer, less repairable scopes might not be. Will be shipped to you freshly calibrated, with instructions book pdf (I’ll need your email to send it; ebay doesn’t give it to me), power cord, and blue face filter (only at my asking price)… READY TO USE !. 2nd photo shows leading edge of a 1MHz square wave whose risetime (and that of the scope) reads about 1.8nS, consistent with the capability of a 200MHz scope. This is a far more stringent test than others showing a scope can display trace zero signal lines or 1KHz signals. 3rd photo shows response of scope to “autoscale+measure volts” of a 1KHz 2Vpp cal source. Note it tells you it goes positive from ground and that it spends more time on than off since the average is slighly more than 1V. 4th shows dual time base mode in action with faster sweep running 10X faster than main sweep and time difference correctly measured between 2 intensified zones. 5th photo shows a scope on top of calibration sources needed to cal/verify such a scope; sellers who don’t have such equipment are going out on a limb when they claim their scope functions correctly. I choose to work on 2400s because they were the last repairable (to component level) scopes Tek made. 2400s are my specialty, so mine shall arrive working correctly, whether you’re buying just 1 or several to outfit an entire lab or classroom. Others sell them because they need fixing, whether their sellers know it or not, I sell them after I’ve fixed them… and that is reflected in my higher prices. Please make sure Ebay has your current correct ship-to address before paying, as that is where I am required to ship. Mistakes are costly to fix after paying as I cannot offer cash refunds, so please go over details before paying. I ship worldwide. Ebay requires I ship with a carrier that provides tracking & delivery confirmation, which Airmail cannot provide internationally, so that rules Airmail out. Ebay has its own Global Shipping Program that offers decent tracking and reasonable rates to many countries. To countries not in EGSP, FEDEX usually offers me the best alternatives. Please do not offer me less than my asking price (you can buy from others for less; even I have some listed for less but with higher hours). I don’t like pay cuts and Ebay already keeps 14% of what you send. Offering less does not incentivize my best effort on your behalf, and understand that if you offer less, you may get a lesser scope. I’d prefer you offer more to get more… such as… you can offer $100 more to get 6 MONTHS GUARANTY (my parts & labor, your shipping) though I realize for some of you far away, round trips to secure service could get expensive, which is why I leave the choice up to you. By the way, if you are offered a 3rd party guaranty extension at checkout, you should ignore it – I have no idea how they operate or if they are qualified to work on 2445Bs. You can also offer $64 for a P6106 or similar 250MHz probe. If Ebay stops you from offering more, I will still sell you what you want, and for 10% less (and less or no tax) once I know you. Ebay as a large e-commerce site, now has to collect sales tax for many of the 50 States. I have no control over that, and I do not charge sales tax on my own out-of-California sales (I am small). If you are outside California and do not feel like paying a large tax, buy something cheap(er) from me first (eg: a probe) and a workaround will present itself. Also, I cannot offer cash refunds (but only store credit) because of differing definitions of “full refund” between Ebay and its payment platforms. One considers full refund to be all you paid; the other considers full refund to be return of all I got. The difference is the fees, shipping, and sales tax that I never see, and I can’t “go into the hole” for you to return more than what I got. Also money coming into a small business gets spent almost as soon as it lands in. Please buy prudently/ask questions first. DISCOUNT on a 2nd item: If you pay asking price, I will offer you a 10% DISCOUNT on next purchase. If you want the 10% discount on this item, buy any cheaper item from me first (eg: a top pouch, a front cover, or even a spare fuse). This should also save you the state sales tax on the scope if you’re outside my state (California). Once you buy a cheaper item first, let me know which scope you want and I’ll enable the discount for you. If you are outside USA, shipping by public Airmail is not available since it does not satisfy Ebay tracking and delivery confirmation requirements. We can use DHL, FEDEX, or UPS (Fedex usually gives me lowest rates) and Ebay’s calculator is sometimes greatly wrong. Can ask me for a quote (and please include your address), or you can have it travel on your account with any of the 3 by selecting “local pickup” option. If not given this option, ask me for a revised invoice before paying. Also, on non-US Ebay sites, price may look higher because Ebay includes import taxes based on BIN price. They will not help you reduce declared value to save you on tax. If you need declared value and tax lowered, we may have to split purchase in 2 payments… for that you have to ask me how before you buy. LOCAL PICKUP INCENTIVE: if you come to me to pick up the scope, I will add a Tek scope cart FREE (carts are impractical to ship). HURRY INCENTIVE: if you pay my asking price today, I will add a Tek 10:1 250MHz probe. Still you may want to buy 1 first to then get the scope for $630.
