**9.1 Diagram for TR Imaging — SanjCONTROLLER PLUS™ signals:**
- **A. VI EXT**: Input for fixed DC voltage up to +60V.
- **B. VO EXT**: Pulsed output of the DC voltage applied to VI EXT.
- **C. AUX INT**: Up to ±10V DC for secondary DUT bias.
- **D. VO INT**: Up to ±10V pulse for DUT pulsed bias.
- **E. TRIG**: Internal-mode output, 5V TTL pulse, syncs an external DUT bias supply.
