A-10 Specifications
Case II: Auto-Zero enabled and measuring two functions
Trigger Latency: 225µsec max
Source Configuration: 50µsec max
A/D Conversion: [NPLC Setting
× (1 / power line frequency)] + 185µsec
Firmware Overhead: 2.3msec for Source V
2.65msec for Source I
Source On Time
≅ Source Configuration + Source Delay + (4 × A/D Conversion) + Firm-
ware Overhead
Example: Source Delay = 0µsec
NPLC Setting = 0.06 PLC
Power Line Frequency = 60Hz
Source On Time
≅ 50µsec + 0 + [(4 × 0.06 × 1/60) + 185µsec] + 2.6msec
≅ 7.1msec for Source V
≅ 7.45msec for Source I
