Just an update about the SYN control. I found the information on page 5 of the MkII manual to be helpful. Mixing in a bit of the Y signal by connecting the Y and SYN jacks and operating the SYN control does seem to help considerably in obtaining a stable trace. The scope will display a stable sinewave of up to 1MHz at less than 100mV. It seems that SYN does work as expected. I just now need to understand the reason for the multi-triggering when the SYN input is not used and whether there is anything that can be done about the deflection between X and Y axes being significantly different.
