I've only had the unit for 4 hours, but, once I zero netted it to 10.0000000MHz it has stayed "spot on" every since.Great value for the price.If you need a stable 10MHz reference and can't afford or use a GPS disciplined oscillator, this unit is an extremely good second choice, or backup.

I bought one reference oscillator and tested it on the bench for one week. I found that the stability is excellent when compared against a GPS-locked frequency standard. The OXCO module is sealed and voltage controlled. The oscillator is used, which is good because an aged crystal tends to be much more stable.I liked the first unit so much that I ordered two more. These make very good replacements for older, much larger power-hungry 10 MHz oscillators. The excellent stability and low phase noise make these a winner.

UPDATE: After soldering on the missing 2R2 inductor I was able to get the unit to work. Here are some pictures from my Oscilloscope. The TTL output jack doesn't have quite as nice of a waveform as the sine output.Poor quality. Missing component on the circuit board. My unit was missing a piece on the circuit board. Either the part was never installed or it broke off at some point. It does not output any signal when power on.

Would not calibrate against my rubidium reference standard. Adjustment did not seem to respond and the closest I could get was around 10 Hz high at 10 MHz no where near the claimed accuracy. I purchased two units and sent one back to Amazon in the hope that the problem with the remaining unit could be resolved. thank youBob, KE6F

The first one I received had insufficient voltage swing to bring the OCXO into 10MHz resonance. It was clear the trimmer pot and associated resistor network would not allow sufficient voltage swing within the specs of the CTI OCXO. I considered modifying the one I had to make it work but decided to instead replace it.The second unit locks perfectly fine on 10 MHz, with some fiddling, surprisingly close to a GPSDO locked on 10MHz.So, if you get a good one, it will work as described. There is some drift but this is expected. The second one has been running for three days continuously against a fairly stable GPSDO and the drift (with periodic minute adjustments) has been fairly small. I have not yet quantized the difference, but it is close enough to call the second one a keeper.These units are likely not tested thoroughly before shipment so it will be hit or miss depending upon the quality of the (clearly surplus/salvaged) OCXO.Not impressed with the quality of wire used for the supplied power supply plug but overall this is likely a minor concern for most.

This oscillator provides a sine wave and square wave output. The frequency is very stable. The fourier transform (FFT) shows no harmonics in the sine wave. A great reference oscillator.
