perfectly working fully tested dual mixer. compatibility guaranteed or your money back. 

works on basically any  6 series analyzer by hp that uses dual mixers.  , ive had success swapping these with 8561e, 8562a and 8563a  etc...with no problems .also seems to work for 9 series with no issues as well since all the values are done automatically instead of manually like on 856xx series. you will need to realign your analyzer with the new values after install.d

30 day warranty for exchange as i have about 3. take your pick.

I currently have one thats from an 8563a, one thats from 8561e and maybe another one, 

I accept Paypal ( I prefer E-check funding if possible, Contact me for information on e-check funding thru paypal)

For test equipment I am the largest used Stanford Research Systems dealer in the world. I am also known for my HP / Agilent spectrum analyzer and function generator sales as well.


 For test equipment I am very knowledgeable with SRS  and HP agilent  equipment : pricing , testing,reconditioning,  and fixing basic issues. Every price that is listed is a price that the same unit sold for before at least  a few times. I am not like the other dealers who list for rediculous prices that no one has ever bought it for in hopes they can make themselves rich. All my prices for musical instruments and scientific electronic test instruments are fair going rate prices.

LIQUIDATION SALE!!!! We dropped prices on almost all our listings by $400! until 2018! act fast - These deals wont last!
IMPORTANT! Due to PayPal's new rule that requires sellers to absorb the 3% fee on any returns. We will need to charge a 3 % restocking fee for any and all returns / refunds. 
NEW POLICY READ!!! 
Buyer to pay shipping for  both ways for all returns.We will repair all parts and labor for no out of pocket cost to you except the shipping .For any refunds there is a 3 % restocking fee unless the item is exchanged which is easier for us often  since we have multiples of these in stock usually . Buyer will also accrue another 3% paypal fee having the money returned by using paypal if paid via paypal originally. (this new rule is because of paypal’s new greedy way of not returning the original fee back on returns/refunds and I regrettably have to bring this new policy to you the buyers.)The point is you will save a lot more money doing an exchange over doing a return
