Dedicated A/D Converters per Channel – help you achieve faster

sampling rates per channel, simultaneous sampling, and better

dynamic accuracy for transient or frequency measurements.

200 mV to 42 V Input Ranges – configure each analog input channel

to read from a very wide variety of voltage ranges. The input

impedance is lower for 20 and 42 V ranges, preserving the bandwidth

for signals with high frequencies and large amplitudes.

AC or DC Coupling – configure analog inputs for AC or DC coupling

on a per-channel basis. AC coupling removes the DC offset for

applications only analyzing signals in the frequency domain.

Antialias Filters (NI 6115 and NI 6120) – the antialias filters are turned

on from software on a per-channel basis. NI 6115 devices have 50 or

500 kHz filters for each channel, and NI 6120 devices have 100 kHz

filters for each channel.

Large Onboard Memory (NI 6115 and NI 6120) – NI 6120 devices

feature a 64 MS onboard memory, and NI 6115 devices feature a

64 or 32 MS onboard memory. With the extra memory, which

requires no extra programming, you can capture high-bandwidth

signals over long periods of time, even if multiple devices are sharing

the same PCI or PXI bus.

Hardware-Timed Digital I/O – the digital I/O lines can synchronize

with the analog input, analog output, counter/timer I/O, or an

external clock for mixed-signal measurement applications. Using the

onboard FIFO, you can achieve reliable data transfers to 10 MB/s.

Phase Locking (PXI only) – synchronize multiple devices to a

common PXI backplane clock to preserve the phase between

measurements across multiple device analog input channels.

Professional Analysis and

Presentation Toolkits

There are several analysis and presentation add-on toolkits available

from National Instruments that help make you more productive

when developing custom applications with your S Series devices.

Turn your S Series device into a transient recorder, spectrum

analyzer, or one of several other instruments with these toolkits.
