Old analog oscilloscope (Advance - Gould OS 240) front panel output

Hi I can't find the exact manual for this pretty simple old oscilloscope (pretty good functionally) - I 've found some pretty similar ones, for other models - so I have a couple of questions regarding the front panel.

There is a small pin labeled Gate o/p. Is this something like a probe callibration output? Next to it there is a "banana plug" socket input for external trigger (obvious) and ground. What this ground is used for (since there is a mains ground similar socket at the back panel).

Here's a photo

Thanks in advance
