The TrueTime XL-DC-602 is a GPS receiver that provides NTP and outputs a highly stable 10 MHz reference. These devices came configured with a large variety of options and it can be difficult to tell exactly what you're going to receive based on just the seller's listing in most cases. My unit outputs 1, 5, and 10 MHz square waves and is not equipped with the sine output option. I'm using a couple of cheap eBay filters to AC couple the output and clean up the signal a bit.
The filtered output level is significantly attenuated but acceptable to drive most of my equipment. Only the Marconi signal generator complains about low reference level when first powered on but the error goes away after a few minutes. Replacing the filters with a Mini-Circuits band pass filter should significantly reduce the attenuation.
For the moment I am using an Extron CVDA 6 MX Dual Composite Video Distribution Amplifier to get the 10 MHz signal out to my test equipment. This device uses an Intersil EL2099 op amp internally. The termination resistors were replaced with 50Ω resistors to give a better match for my cables and test equipment. One drawback of this unit is lack of isolation between ports. At some point in the future I plan to design a distribution amplifier with port isolation.
