How can I tell if my AN/PVS-7B is auto gated

I picked up 5 sets of ITT AN/PVS-7B Gen 3 night vision goggles at a government auction.   How can I tell if these are auto gated?

Took this from another site.

What does “autogated” mean?

Auto-Gating constantly operates to improve the quality of the image, not only during day-night-day transition, but also under dynamic lighting conditions.

When the power supply is “auto-gated,” it means the system is turning itself on and off at a very rapid rate.  This, combined with a thin film attached to the microchannel plate (an ion barrier) reduces blooming.  While “blooming” can be noticeably less on systems with a thin film layer, systems with thicker film layers can be perfectly acceptable depending on the end user’s application.  Deciding which night vision goggle is better should not be based solely on blooming.

Maybe you can use the model number if you have one.

Need more details in general about the units.  I’m interested in the whole process.
