Channel Configuration

• 32-channel fully differential analog input (single-ended input not supported)
• Channel-to-ground basic noise suppression without channel-to-channel isolation
• All channels multiplexed to one DAQ analog input channel

Programmable Input Parameters

• Input voltage range: ±50 V maximum differential input
• Programmable gain multiples: ×1, ×2, ×5, ×10, ×20, ×50, ×100
• Input coupling: DC-only coupling (no AC coupling option)

On-board Low-pass Filter Parameters

• Fixed 10 kHz 4th-order low-pass filter: Maximum scan rate 12 kS/s
• No optional bypass or low-frequency filter gears
• Unable to suppress 50/60Hz power frequency interference without external filtering

Key Electrical Specifications
