4:00 Automatic brightness control is a function of the tube’s PSU, not the NVG housing. Autogating turns off and on the photocathode voltage rapidly but the effect is not visible to the human eye. The cathode voltage is constantly oscillating, but the image appears as if it were continuous. The autogating circuit reduces the time the voltage is on during each oscillation but keeps the peak voltage level up. By controlling the application of voltage in this manner, the resolution quality remains high. This also helps protect the tube in high light environments. Automatic Brightness Control (ABC): IE autogain. Automatically reduces voltage to the microchannel plate to keep the image intensifier output brightness within optimal limits and to protect both the tube and the user’s eyes. This effect can be seen during rapid changes from low-light to high-light conditions when the image gets brighter and then quickly returns to a consistent level. Manual gain tubes still feature automatic brightness control.
The board that does the work for ABC and the sensor is external to the tube itself. This is all we were trying to convey to folks, nothing more. The sensor that sees the high light for the ABC to function is also in the housing not inside the tube itself. Remove the tube from the housing and ABC does not work or exist. Technically with the tube removed from the housing if you power up the tube Autogating could still occur because its internal to the tube. Technically there is no such thing as AutoGain. There are some manufacturers that call it that but really these are non gain or fixed gain systems they are referring to when they say auto gain. There is no technology that automatically adjusts the gain for you. Automatic Brightness Control simply cuts the power off to the tube very quickly for a spilt second during a bright light flash to protect the tube. All these words are very confusing and misleading at times and we know for a fact there is a bunch of very misleading information in existence on this topic.
@@Arkayne Did you even read the comment?? It is 100% correct. YOU are describing the high light shutoff feature, which every modern nvg since the pvs7 has had, although this one seems a little different. This would be an easy change to the video script or put as a clarification in the comments "Our housing has a high light shutoff feature which will cut power to the tube while a bright light is visible". "Technically there is no such thing as AutoGain" - Autogain is just another name for automatic brightness control. It exists. "There is no technology that automatically adjusts the gain for you" - Yes there is, it's called automatic brightness control, and even some of the later first generation tubes have it. EVERY second and third generation tube has it, regardless of whether it has a "manual" gain feature. "Automatic Brightness Control simply cuts the power off to the tube very quickly for a spilt second during a bright light flash to protect the tube" - No. The BRIGHTNESS of the screen is adjusted proportionally to the brightness of the environment. If the environment becomes lighter, the image is dimmed slightly to give roughly the same brightness instead of just blasting your eyes. "non gain or fixed gain systems" - These simply do not exist anymore. The only true "fixed gain" systems are the ones that use earlier generation 0 and generation 1 tubes, with those, any bright light will just damage the tube instantly. You trashtalk even though it's clear you have no clue what you are talking about. It's crazy that a company that is selling night vision devices doesn't know this and is ready to argue about it. It just makes you as a company look bad imo. "All these words are very confusing and misleading" gaslighting people ON YOUR CHANNEL! is unacceptable.
You are describing the high light cut off of the housing, not the ABC or autogating function of the tube. Automatic brightness control is very much a thing, and is a characteristic of the tube itself. You are describing autogating, not automatic brightness control. ABC adjusts voltage to the micro channel plate, autogating alternates voltage to the photocathode. Neither of these are turning the tube off, they make changes to voltage to certain parts of the tube.
@@go_horse 100% right. Just a small correction. BSP is the Gain voltage part. Auto-gating is the on/off/on/off part. ABC only adjust the phosphor screen brightness! Not the gain :) And then auto shutoff what Arkayne describes 🤣

Personally I would pay to see a more in depth review of both the lower fom and higher fom units. Personally I’m looking to buy my first night vision unit and I am leaning towards binos. I have been holding off on buying a unit because I found your no bs videos. Now I’m questioning if spending 8500+ on binos is really worth it after seeing the Jerry 31 and rnv 31. I don’t want to overspend to “flex” if I can spend a little over half my budget and it fit my use.. and after seeing the 1600 vs 1800 I’m questioning if the extra 2000 is even worth it for what I’m doing
Your on the right track! While the RNV-31 is still technically an entry level unit to us it definitely offers tremendous value for the money. If your going to spend close to 9K on Binos check out the PD-Pro Binos on our site from Photonis Defense. The PD-Pro Bino is a very small very light weight aluminum housing that takes the cake as an advanced set of Binos. Pick your poison we can get you set up. If you have more questions email us CS@ARKAYNE.COM 👊🏽
@@ZroCool_Garage Yes it will, both RNV devices come with the Adaptor to interface with the CE5 without needing the circular ring clamp used on Mil spec PVS-14’s. That feature was NOT lost.
@@CK-jb8qh Those units are not “obsolete” by any stretch, and the more expensive tubes in a RNV-31 rivals other Bino prices so if your going to spend that much looking at all options is always wise.

@@Roamingeast Doesn't have to be better by a huge margin, just in the affordable range with comparable or slightly better features. I've used the NNVT tubes and can't argue that they are decent for the price, but would never want to support a hostile nation's war chest just to be night vision capable. Other countries need to start looking into this market and making an effort to fill in the market gap.

If you post this video on 4chan, the autist will geolocate the exact location in about 20 minutes.
What I’d like to see is the SNR rating on the 1400-1600 FOM tubes, as well as the 1800-2000.
Do they shut off like the jerrys when you flip them up or rotate them out?
Yes

does the auto shut off for the rnv31s flipping off to the side use physical switches or accelerometers

Are you sure the upgraded 2000FOM isn't a NNVT5 Auto-Gated? I didn't know NNVT 6 even existed.
Same tube, new housing. I'll be impressed when a better budget tube is available from anywhere but china.
then you'll wait a long time. anyone else that can make it 'better' will charge significantly more.
