Заглавие:  Покупка / избор на осцилоскоп?

Иска ми се да си подновя малко техниката че много ретро ми е осцилоскопчето, поразгледах и си харесах този - GOS-622G осцилоскоп аналогов 2x20MHz Instek - http://www.electroninvest.com/shop/item ... =100037651. Към 750лв. ама в Електронинвест го нямат в наличност. Някой ако го е ползвал този модел да сподели отзиви и евентулно дали да си взема нещо друго за около тези пари, не ми се дават повече, рядко ползвам осцилоскоп но искам да имам приличен като ми се наложи?

За този модел няма никакви наблюдения. И аз искам да си купувам скоро време, ама ще се върна първо в България, после и работа трябва да си намеря, че чак тогава. Но от сега съм си се спрял вече на модел. Теktronix TDS1000B Series • TDS2000B Series - TDS1002B. Цената на новия модел TDS1001B е 765 евро, а на този който съм харесал е 918.

Но смятам да си го взема refurbished от тях директно. Дават го с 25% намаление така че си е на далавера :)
Цени за България на чисто новите.

Според мен @GTN правилно насочва фокуса към DSO. Докато се рових из нета за проекти, попаднах на доста готови тип "кит" (е не маркови, но изглеждащи добре) с прилични параметри и на що годе прилични цени. В рамките на парите които си приготвил има много и с по-добри показатели от този който си харесал. Обаче са без екран - само към PC.

Аз ли съм смотан, щото нещо не мога да ги намеря тия добрите осцилоскопи за PC?

А в Tektronix отдавна не бях надничал, и тия цени ме изненадаха приятно. GTN, какъв е номерът с намалението, ако не е тайна?

Заглавие: 

Идеята е от различни презентаци демонстрации и/или върнати осцилоскопи, малко ги доуправят ако има проблем и ги продават наново. Калибрирани са си, имат си нормалната гаранция. Само е възможно да има някакви драскотини или други подобни цапаници които само външния вид загрозяват.

More About TekSelect

Now you can buy direct from the factory at great savings. We understand that your budget constraints might affect your ability to buy new. We provide products that will do the job, at a price that won't break your budget.

When you have a special project with tight deadlines and waiting for an instrument simply won't do, TekSelect may offer a solution for you. In many cases, products have been reconditioned in advance and are available for immediate delivery. For those products not reconditioned in advance, or for products requiring reconfiguration, some lead-time is required for us to properly recondition your TekSelect product or install the added options you purchased. Your CSS will help you understand the required lead-time for delivery.

Frequently Asked Questions

Q: Where do TekSelect products originate?
A: TekSelect inventory comes from various sources

* Former demonstration units
* Special events such as the Olympics or trade shows
* Excess factory inventory
* Customer returns

Q: What warranty is included on a TekSelect product?
A: TekSelect products are sold with the same warranty as our new products. Extended service options are also available on most products.

Q: What performance can be expected from a TekSelect product?
A: TekSelect products are reconditioned to factory specifications and meet the same high standards of quality that you've come to expect from Tektronix. You never sacrifice performance when purchasing a TekSelect product.

Q: Are TekSelect products the same configuration as what is currently being produced as new products?
A: All products are reconditioned to the configuration they were in when originally manufactured. Tektronix does not represent that TekSelect products will match the current option configuration offered in new products.

Q: What operating system and firmware is included?
A: Unless otherwise noted, the operating system and firmware is the same that is currently shipping with a new product.

Q: What is the appearance and condition of a TekSelect product?
A: Because these most likely are used products, you'll probably notice normal wear and tear on them. What you sacrifice in aesthetics, however, you make up for in price and functionality. Remember that while the TekSelect products may have a few dings and scratches, they come with a standard product warranty at substantial savings from the list price. We stand behind our TekSelect products.

Q: Can a unit be reserved?
A: Reconditioned products are subject to availability upon receipt of a purchase order. A unit cannot be reserved without a purchase order.

Q: Can options be added to a TekSelect product?
A: In most cases an option can be added to a TekSelect product. If there is an upgrade kit available to add the desired option, we can add it.

Q: Will the option being added get the same discount as the main unit?
A: Yes, for soft options activated by a keycode or dongle as long as the unit has not already been reconditioned (those with a 1 week or less delivery). Eligible soft options are outlined in a note on the TekSelect availability list. The option must be ordered as an option to the main unit not as a separate upgrade kit. Hardware option upgrades are ordered as an upgrade kit on a separate line at list price.

Q: When are installation charges applied to option additions?
A: Installations charges will normally apply for option additions to units that have already been reconditioned (units that show a 1 week or less delivery). Installation charges will not be incurred if we install the option during the reconditioning process.

Q: Can options be removed from a TekSelect product?
A: Yes, but only if it is a soft option activated by a keycode or dongle or if the option being removed is a separate model (e.g. probe, cart, etc.) and the unit does not have a delivery of 1 week or less.

Q: Can power cord or manual language options be changed?
A: Power cord options (A0-A99) or manual language options (L0-L9) can be modified to match your local language and power source. We will make these changes regardless of the delivery lead-time advertised.

Q: What delivery can be expected for a TekSelect product?
A: Our delivery estimate is shown on the availability list. The total lead-time for a product getting a hardware option installed will be the lead-time of the upgrade kit plus 5 weeks. Allow 2 additional weeks when ordering a product from outside the geographic region that you reside.

Q: What other terms and conditions apply?
A: Except as noted above, Tektronix General Terms and Conditions of Sale apply. For the United States or Canada region, pricing is exclusive of taxes, shipping and insurance.

И за другите модели си има отстъпки но тези лично за мене като за първи осцилоскоп си заслужава най-много

Благодаря!

На 2022/2024 даже е 35%

Сега си спомням, че преди 3-4 години Ню Тек ми споменаваха за тази програма, но тогава разговорът ни беше за логически анализатор.

@ JoroS Напълно си прав :) В последствие може да се появи и по-голяма отстъпка. Иначе има отстъпка за всички тяхни продукти.

Ето едно полезно четиво за избор на осцилоскоп.

Хм, оказва се че моделите с отстъпката са от старата серия - без B отзад. Тоест без интерфейсите. А да си ги купиш допълнително е почти толкова, като да вземеш от новите на нормалната цена.

Мдаааа не бях видял разликата. Но все пак положението не е толкова лошо. Няма USB но си има RS232. По него може да го управляваш и сваляш данни, а за запис на картинки използваш CF карта, която е от най-евтините.
