F.7.10 COAX
F.7.11 J26 - LOG Video Input (RF TEST-IN)
Connector Type: 50 BNC
Description: Baseband detected pulse:
- Analog input range: 0.5 V to 2.5 V, low frequency/DC
- Input Impedance: 90 ohms
- Settling time: Input has a settling time of 7 usec
- Gain: 1 V/V nominal
- Circuit description: Input is treated as a differential input. The circuit
has an active input electronics to isolate signal and signal ground from
the panel and RVP9IFDR ground noise. If the ground reference drifts
from the panel's signal ground, the gain deviates from its nominal
value. Use a well-shielded cable if noise enters the signal or ground
reference; it influences readings.
F.7.12 J27 - Spare Analog Input (SPARE)
Connector Type: 50 ohm BNC
Description: Spare, maybe use instead of or in addition to:
- Analog input range: +/- 3V, low frequency/DC
- Input Impedance: 100 ohms
- Settling time: Input has a settling time of 500 usec
- Gain: 1 V/V
