Overview

Product overview

Key product information and technical features.

The PXI-6120 combines simultaneous analog acquisition with analog generation, digital I/O and counter functions in a PXI module. NI identifies synchronized stimulus/response measurements as a product-relevant application.

Its four analog inputs are pseudodifferential and support AC or DC coupling. Selectable input ranges extend from ±0.2 V to ±42 V; observe the separate working-voltage limits for positive and negative input terminals.

Simultaneous sampling across four 16-bit analog input channels.
Selectable bipolar analog input ranges from ±0.2 V through ±42 V.
AC and DC input coupling.
Two 16-bit voltage outputs with a ±10 V output range.
Eight digital I/O lines, two 24-bit counters and digital triggering.

FAQ

Product-specific questions

Product-specific answers based on available technical information.

Does the PXI-6120 sample its analog inputs simultaneously?

Yes. Its four analog input channels sample simultaneously with 16-bit resolution at a documented maximum of 800 kS/s per channel.

Does it provide analog outputs?

Yes. The specifications list two 16-bit voltage outputs with a ±10 V range. Maximum update rates are system dependent: 4 MS/s for one channel or 2.5 MS/s for two channels.

Which signal cable does NI recommend?

NI lists the SH68-68-EPM as the recommended shielded cable for the 6115/6120 group. The PXI-6120 uses a 68-pin SCSI 0.050 D-Type front connector.
