Check the listing for details. TEKTRONIX P6201 DC-900MHzActive FET probe for oscilloscopes. Condition: Used. Listed at 400.00 USD. At $400 BIN, I shall send you a good used P6201 probe (accessorized as in photo). These cost $1800 new from Tek. Includes manual. A FETprobe enables reduced loading, especially capacitive, at test points, which is vital for high frequency work where even a few pF can act almost like a dead short. Since the dynamic range of the probe (gate of a FET) used directly is only 6V, it comes with a divide by ten and a divide by 100 attenuator. I don't like pay cuts and Ebay already keeps 14% of what you send me. If you offer me less than BIN, you are consenting to getting fewer accessories or and/or an untested probe, so please resist the temptation if you want it all.Please make sure Ebay has your correct ship-to address before you pay. Correcting mistakes after you pay is costly as I cannot offer refunds but only store credit. I ship worldwide. Ebay requires I requires I ship with a carrier that provides tracking & delivery confirmation (to address on file at time of payment), which Airmail cannot provide internationally, and rules them out for outside US. Ebay is now required by many of the 50 States to collect sales tax (may spread to all), and I have no control over that & I do not collect sales tax on my own out-of-California sales. INCENTIVE: after you BIN any item from me, I will offer you a 10% discount on a subsequent item. This means if you plan to buy a scope from me, you will save more by buying the probe first, then the scope.
