The NI 9229E/9239E has four 2-terminal detachable  
screw-terminal connectors.  
Note You must use 2-wire ferrules to create a secure  
connection when connecting more than one wire to a  
single terminal on the NI 9229E/9239E.  
You can connect ground-referenced or floating signal sources to  
the NI 9229E/9239E. Connect the positive signal of the signal  
source to the AI+ terminal, and connect the negative signal of the  
signal source to the AI– terminal. If you make a ground-referenced  
connection between the signal source and the NI 9229E/9239E,  
make sure the voltage on the AI+ and AI– connections are in the  
channel-to-earth safety voltage range to ensure proper operation of  
the NI 9229E/9239E. Refer to the Specifications section for more  
information about operating voltages and overvoltage protection.  
Refer to Figures 3 and 4 for illustrations of how to connect  
grounded and floating signal sources to the NI 9229E/9239E.

The NI 9229E/9239E analog input channels are floating with  
respect to earth ground and each other. The incoming analog signal  
on each channel is conditioned, buffered, and then sampled by a  
24-bit Delta-Sigma ADC.  
Each channel provides an independent signal path and ADC,  
enabling you to sample all four channels simultaneously. Refer  
to Figure 5 for an illustration of the circuitry for one channel.

Understanding NI 9229E/9239E Filtering  
The NI 9229E/9239E uses a combination of analog and digital  
filtering to provide an accurate representation of in-band signals  
while rejecting out-of-band signals. The filters discriminate  
between signals based on the frequency range, or bandwidth, of  
the signal. The three important bandwidths to consider are the  
passband, the stopband, and the alias-free bandwidth.  
The NI 9229E/9239E represents signals within the passband, as  
quantified primarily by passband flatness and phase nonlinearity.  
All signals that appear in the alias-free bandwidth are either  
unaliased signals or signals that have been filtered by at least  
the amount of the stopband rejection.  
Passband  
The signals within the passband have frequency-dependent gain or  
attenuation. The small amount of variation in gain with respect to  
frequency is called the passband flatness. The digital filters of the  
NI 9229E/9239E adjust the frequency range of the passband to  
match the data rate. Therefore, the amount of gain or attenuation at  
a given frequency depends on the data rate. Figure 6 shows typical  
passband flatness for the NI 9229E/9239E.

Stopband  
The filter significantly attenuates all signals above the stopband  
frequency. The primary goal of the filter is to prevent aliasing.  
Therefore, the stopband frequency scales precisely with the data  
rate. The stopband rejection is the minimum amount of attenuation  
applied by the filter to all signals with frequencies within the  
stopband.  
Alias-Free Bandwidth  
Any signal that appears in the alias-free bandwidth of the  
NI 9229E/9239E is not an aliased artifact of signals at a higher  
frequency. The alias-free bandwidth is defined by the ability of the  
filter to reject frequencies above the stopband frequency and equals  
the data rate minus the stopband frequency.  
Understanding NI 9229E/9239E Data Rates  
The frequency of a master timebase ( fM) controls the data rate ( fs)  
of the NI 9229E/9239E. The NI 9229E/9239E includes an internal  
master timebase with a frequency of 12.8 MHz, but the module  
also can accept an external master timebase or export its  
own master timebase. To synchronize the data rate of an  
NI 9229E/9239E with other modules that use master timebases  
NI 9229E/9239E  
10  
ni.com  
 
 
to control sampling, all of the modules must share a single master  
timebase source. Refer to the software help for information about  
configuring the master timebase source for the NI 9229E/9239E.  
Visit ni.com/info and enter cseriesdoc for information about  
C Series documentation.  
The following equation provides the available data rates of the  
NI 9229E/9239E:  
f
÷ 256  
n
--M------------------  
fs =  
where n is any integer from 1 to 31.  
However, the data rate must remain within the appropriate data rate  
range. Refer to the Specifications section for more information  
about the data rate range. When using the internal master timebase  
of 12.8 MHz, the result is data rates of 50 kS/s, 25 kS/s, 16.67 kS/s,  
and so on down to 1.613 kS/s, depending on the value of n. When  
using an external timebase with a frequency other than 12.8 MHz,  
the NI 9229E/9239E has a different set of data rates.

Sleep Mode  
This module supports a low-power sleep mode. Support for sleep  
mode at the system level depends on the chassis that the module is  
plugged into. Refer to the chassis manual for information about  
support for sleep mode. If the chassis supports sleep mode, refer to  
the software help for information about enabling sleep mode. Visit  
ni.com/info and enter cseriesdoc for information about  
C Series documentation.  
Typically, when a system is in sleep mode, you cannot  
communicate with the modules. In sleep mode, the system  
consumes minimal power and may dissipate less heat than it does  
in normal mode. Refer to the Specifications section for more  
information about power consumption and thermal dissipation.
