IMD and gain measurement using PSG analog ramp sweep

I would like to do the following measurement using the analog PSG with the ramp sweep option.

1. swept IMD measurements using two PSGs by generating two tones that are 1MHz apart and doing an analog ramp sweep. I connect the o/p of the PSG to my device and measure the output of the device on a sectrum analyzer. The frequencies are at 6GHz and 14GHz

How do I synchronise the two PSGs to start the sweep at the same time and end at the same time? I also need to trigger the spectrum analyzer for the measurement.

I find that on the PSG, the sweep times are not exactly the same for different units.
