Tektronix 878-1625-XX MDO34/MDO32 Main Board 100 MHz- 1 GHz 2CH-4CH
Original listing includes 4 separate boards.
All board power up into the scope environment.
All boards passes all power up tests, with exception of CPU test which checks that the board serial number matches what is programmed into the scope. This is an expected failure when a board change occurs, and can be ignored.
None of the board includes any software entitlements or options.
One board appears stuck on an old firmware version and cannot be upgraded. Others have more recent firmware
P.S. The same board is used on ALL models, from 100 MHz to 1 GHz. The scope bandwidth is controlled by license key. The number of analog channels on the scope determines whether it is a MDO32 or MDO34. The board was tested in a 2 channel mainframe, hence why it shows MDO32.
Also note that because the serial number is programmed into the board, and the board carries the license, you cannot swap this board into your instrument and achieve the similar setup as before (1 GHz scope with 3 GHz Spec An for example), without a license specific to the serial number of the board you receive.
Hence, this is best used for parts or repair of your instrument.

MEET YOUR SELLER:
I offer a wide selection of Genuine Tech and Electronics Items from some of the leading manufacturers, the majority of which are sourced directly from Tektronix. Every item presented for sale is carefully inspected and examined before listing. Where appropriate, more information is provided, with the information I think you would want to know. With very few exceptions, "Used" items are pulled from working environments (manufacturing areas, engineering, marketing or sales, and occasionally customer upgrades). "New" and "New -Other" items are usually unsold overstock items. My high positive feedback rating (while selling used electronics) is a testament to the work I put in to acquire, verify and sell quality items. Buy with the utmost confidence.
TESTING:
New items are rarely ever tested. Used items are tested to the extent I have the capability. Given the wide variety of items sold, it would be impossible to test everything. I rely on my sourcing methods and provenance to only sell good working units, and any item not working is listed as such. Many items in store are decades old, and will have imperfections. They may also be subject to the hazards of transportation. Electronics also fail, and are sometimes intermittent. In the unlikely event an item differs materially from what is listed I will gladly work with you to resolve any issues. Unless stated, items are never calibrated before sale.
DOMESTIC SHIPPING:
All items will be appropriately packaged and shipped to you using the fastest possible method given what you have paid for shipping. Free shipping items are also shipped with the fastest reasonable method. Most items are shipped the same day from the west coast, ensuring items get to you even faster.
INTERNATIONAL SHIPPING:
I have had the pleasure of selling to customers in all parts of the world. Thank you for your trust over the years. Most items are available to purchase through the eBay Global Shipping Program. I am also able to ship items to most countries directly, using your account. This includes high value items that require export documentation. I do charge for this as it is very time consuming. Please contact me directly before buying if you wish to have items shipped directly to you.
PAYMENTS:
Standard payment methods are accepted. For high value purchases, I can also accept wires. Buyer pays all wire fees, including any charged by my bank. Please contact me directly before to discuss these options.
RETURNS:
In the unfortunate event that you believe the items needs to be returned, please be sure to contact me first. Because of the complexity of international transactions, international returns are not accepted. Please ask all questions before purchasing. Refunds for returned items are promptly processed once item is confirmed to be as it was shipped (unopened/unaltered/quantity).
