Maybe quasi-simultaneously is adequate, using a switch to sample the 3 pairs in rotation.
The HP59307A can be used for that under GPIB control. I would think the main reason for doing it simultaneously is so that whatever source of error exists (temperature, vibration, etc) will affect the 3 oscillators the same way. The switch won't help with vibration, but it will help with temperature and other slow changing variables, such as time of day.
