This has been fully tested with my signal generator and works with no issues , warranty will be for exchanges within 30 days!. I have thoroughly tested all of the functions and it passes all my freq response ,amplitude accuracy , noise-floor sensitivity,flatness, attenuator, and stability tests flawlessly within spec and is guaranteed to re-calibrate with no issues! .the waveform even at super high frequencies with low spans, on this unit has excellent shape with no spikes at low spans / bandwidths. you may be able to find one cheaper on ebay but not one this thoroughly tested or freshly calibrated and realigned . chances are that they will not be able to calibrate without repairs. even if they are offering warranty, Its good odds that there is an issue or they are hoping you wont send it in for cal because it would fail.

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
