Stanford research SR810 dsp lock-in-amplifier 100 khz


This is a refurbished stanford research systems sr810 digital(dsp)lock in amp like the sr844 and sr830 models and also like the sr850 I also have for sale.
it costs 3850$ new and sells for about 60 to 70 percent new price on the used market. the lock in amps are srs' most popular products thus why they sell for so high. and Im expecting this to sell within the week.
I have sold over 30 lock in amps by srs in the last 4 years. this one is tested good with no issues. and guaranteed good for 14 days or your money back!
cosmetically its in excellent condition, near new, with only some microscopic scratches on the casing.
* 1 mHz to 102.4 kHz frequency range
* 0.01 degree phase resolution
* Synthesized reference source
* GPIB and RS-232 interfaces
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.
Pickup is completely fine as well> I am located 50 minutes from Salt Lake City UTAH and Have another house In southern California.
