8 Single-Event Transients (SET)
SET are defined as heavy-ion induced transients on the VOUT, CPOUT, VREF, or PG signals of the TPS7H1301-SP. Testing was performed at room temperature (no external temperature control applied). The species used for the SET testing was 169Tm at 19.5MeV/nucleon (KSEE) and 165Ho at 15MeV/nucleon (TAMU) (for more details refer to Table 5-1). Flux of ≈105 ions/cm2/s and a fluence of ≈107 ions/cm2 per run were used for the SET characterization discussed.
Waveform size, sample rate, trigger type, value, and signal for all scopes used is presented on Table 8-1.
Scope Model | Trigger Signal | Trigger Type | Trigger Value | Record Length | Sample Rate |
|---|---|---|---|---|---|
PXIe-5172 (1) | VOUT | Window | ±3% | 10k | 100MS/s |
| PXIe-5172 (2) | CPOUT | Window | ±3% | 10k | 100MS/s |
PXIe-5172 (3) | VREF | Window | ±5% | 10k | 100MS/s |
PXIe-5172 (4) | PG | Edge Negative | 20% | 10k | 100MS/s |
The primary signals monitored during testing were VOUT and CPOUT by using a PXIe-5172 triggering using a window trigger at |3%|. VREF was also monitored using a PXIe-5172 triggering on a window trigger at |5%|. The fourth signal monitored was PG using a PXIe-5172 with a edge-negative trigger at 20% lower than the nominal value of this signal. All of these signals were monitored and triggered on their own independent NI PXIe-5172 cards.
The SET results for 2 production and 4 pre-production devices are shown in Table 8-4. As there were no upsets on PG, there is high confidence that the TPS7H1301-SP is SEFI free and the recorded transient events on the other 3 signals indicate that this device has a very low upper-bound cross-section against SETs, as presented in Table 8-3.
