Overview

Product overview

Key product information and technical features.

This OEM version provides the USB-6343 functionality without an enclosure, using board-level connections rather than the enclosed model's terminal arrangement.

  • Selectable analog input ranges of ±0.2, ±1, ±5 and ±10 V.
  • Four 32-bit counters/timers support pulse, encoder and frequency tasks.
  • NI-STC3 provides independent analog and digital timing engines.
  • Five mounting holes support installation in a customer chassis.

FAQ

Product-specific questions

Product-specific answers based on available technical information.

Is this the enclosed USB-6343?

No. The OEM version is a board-only design with generic I/O headers, intended for integration into equipment.

Can all four analog outputs run at 900 kS/s?

No. The 900 kS/s maximum applies to one output channel. With all four channels updating, the maximum is 719 kS/s per channel.

Does the board need external power?

Yes. The OEM guide specifies an external 11–30 V DC, 30 W supply.
