Description
Product Introduction
The DS3800NGRA1F1F is the nuclear-hardened version of the general-purpose remote adapter—the NGRA built for installations where radiation tolerance is as important as reliability. The suffix tells the story: the first “1” indicates a hardware revision with improved signal conditioning. The “F” specifies extended temperature range components with higher-grade capacitors and oscillators. The second “1” adds enhanced diagnostic features (configuration verification, link quality monitoring). The final “F” is the nuclear-hardened environmental package: radiation-hardened components rated for 1 Mrad total dose, neutron fluence tolerance, and MIL-STD-461G EMP protection. This board was designed for installations where standard boards would fail—nuclear facilities, high-radiation environments, or critical infrastructure where EMP protection is required.
The radiation-hardened components (1 Mrad total dose, neutron fluence tolerance) and EMP protection ensure the board survives in extreme environments. The conformal coating provides protection against humidity and dust. Compare this to the NGRA1F1B (extended temperature, diagnostics, coating, but standard commercial components). The 1F1F is for customers who need the highest possible radiation tolerance.

Compatible Replacement Models
| Model | Compatibility Level | Notes |
|---|---|---|
| DS3800NGRA1F1B | ⚠️ Software Compatible | Same extended temperature range and diagnostics, but standard commercial components (no radiation hardening). If you don’t need radiation tolerance, this is a cost-effective alternative. |
| DS3800NGRA1F | ⚠️ Software Compatible | Extended temperature range without enhanced diagnostics. |
| DS3800NGRA1F1 | ⚠️ Software Compatible | Enhanced diagnostics and extended temperature range, but single-layer coating without radiation hardening. |
| DS3800NGRA | ❌ Functionally Incompatible | Base model. No diagnostics, no coating, standard temperature range. Not suitable for any radiation-prone environment. |
Frequently Asked Questions (FAQ)
What makes the “F” suffix different from the “B”?
The final “F” adds nuclear hardening—radiation-hardened components rated for 1 Mrad total dose, neutron fluence tolerance, and MIL-STD-461G EMP protection. The “B” has standard commercial components. The “F” is designed to survive nuclear and high-radiation environments; the “B” is not.
What’s the difference between the NGRA1F1F and the NGRA1F1B?
The 1F1F has nuclear-hardened components and EMP protection. The 1F1B has standard commercial components. The extended temperature range, enhanced diagnostics, and conformal coating are the same on both boards. The 1F1F is for radiation-prone environments; the 1F1B is for standard industrial environments.
What’s the radiation tolerance of this board?
The board is rated for 1 Mrad total ionizing dose and 10^12 n/cm² neutron fluence. The components are latch-up protected and SEE immune. The board also includes MIL-STD-461G EMP protection.
Do I need to upgrade my DMP firmware for the enhanced diagnostics?
The enhanced diagnostics require DMP firmware v3.0 or later. Older firmware won’t recognize the diagnostic registers. We can provide the firmware EPROMs if you need them.
How is the NGRA configured?
The NGRA is configured via jumpers on the board or through firmware settings. If you’re replacing a failed NGRA, photograph the jumper settings before removing the old board. The Config OK LED will verify that the settings are correct.
Can I hot-swap this board?
No. Mark IV backplanes are not hot-swappable. Power down the cabinet, lock out the breaker, and wait 60 seconds before removing or installing the board.
What’s your warranty and lead time?
We stock the NGRA1F1F in limited quantities. Lead time is 2-3 business days. We offer a 2-year warranty. We test every board with a 48-hour burn-in and a full diagnostic verification. The test report is included.
Is this board compatible with the Mark VIe?
No. This board is for Mark IV systems only. The backplane architecture is different.
