Analog Input Channels• Analog threshold trigger – For the DT9837 module
only, the start trigger event occurs when the signal
attached to analog input channel 0 rises above 1.0 V(the fixed threshold level). Specify the start trigger
source as a positive threshold trigger, and thethreshold trigger channel as channel 0.

The DT9837 Series modules support four, single-ended
analog input channels. All analog input channels are
simultaneously clocked. Software-selectable gains of
1 and 10 provide effective input ranges of ±10 V and±1 V, respectively. The DT9837 Series modules use 24-bit
Delta-Sigma analog-to-digital converters (ADCs) thatprovide anti-aliasing filters based on the clock rate. Thesefilters remove aliasing, which is a condition where highfrequency input components erroneously appear as
lower frequencies after sampling.

For the DT9837A and DT9837B modules, the start
trigger event occurs when the signal attached toanalog input channel 0 rises above a user-specified
threshold value. Using software, specify the start
trigger source as a positive threshold trigger, thethreshold trigger channel as channel 0, and thethreshold level as a value between 0.2 V to 9.8 V.

IEPE Functions

For the DT9837C module, the start trigger event
occurs when the signal attached to a specified
analog input channel in the channel list rises orfalls below a user-specified threshold value. Any of
the analog input channels can be used as the start
trigger. The threshold value is programmable (±10 V
for a gain of 1 or ±1 V for a gain of 10).

Applications that require accelerometer, vibration, noise,or sonar measurements often use IEPE sensors. IEPE
conditioning is built-in to the analog input circuitry of
the DT9837 Series modules. The modules support thefollowing software-programmable IEPE functions foreach of the four analog inputs:• Excitation current source – The DT9837, DT9837A,
and DT9837B modules provide an internal excitation
current source of 4 mA. The DT9837C module
provides an internal excitation current source of
2 mA.
• Coupling type – AC coupling or DC coupling can beselected.
The DT9837C also provides a 1 Hz high-pass filter.

Tachometer Input Features
The DT9837, DT9837A, and DT9837B modules accept
one ±30 V, 32-bit tachometer input signal. (The DT9837C
does not support a tachometer input.) On the DT9837,
this signal has a maximum frequency of 380 kHz and aminimum pulse width of 1.3 μs. On the DT9837A andDT9837B, this signal has a maximum frequency of 1 MHz
and a minimum pulse width of 0.4 μs. The thresholdvoltage is fixed at +2 V with 0.5 V of hysteresis.

Programmable A/D Clock
The DT9837 Series modules support an internal clock,which is derived from the USB clock. Use software to
specify the internal clock source and the frequency atwhich to pace the input and output operations and to
start the sample clock. For the DT9837 and DT9837A, thesampling frequency ranges from 195.3 Hz to 52.734 kHz.
For the DT9837B and DT9837C, the sampling frequency
ranges from 195.3 Hz to 105.469 kHz.

You can measure the frequency or period of thetachometer input signal using tachometer counter 0.
On the DT9837A and DT9837B modules, you can alsomeasure the phase of the tachometer input signal in
relation to the A/D sample using tachometer counter 1.

Frequency or Period Measurements – Tachometer
Counter 0
Use frequency or period measurements to calculate therotation speed for high-level (±30 V) tachometer input
signals. An internal 12 MHz counter (tachometer counter0) is used for the measurement, yielding a resolution of
83 ns (1/12 MHz).

Input Triggers
A trigger is an event that occurs based on a specified setof conditions.
The DT9837 Series modules support the following input
trigger sources for the start trigger:

The following parameters for tachometer counter 0 can
be configured:• Software trigger – A software trigger event occurs
when you start the analog input operation insoftware.
• External digital (TTL) trigger – An external digital(TTL) trigger event occurs when the module detects
a rising-edge transition on the signal connected to
the Ext Trig BNC connector on the module.

(508) 946-5100• The starting edge of the tachometer input signal touse for the measurement (rising or falling edge). On
the DT9837 module, the starting edge is always therising edge.
• The value read between measurements (either zero,the default value, or the previous measurement
value). On the DT9837 module, this value is always
the previous measurement value.

By connecting a rotating device to the tachometer input of the DT9837A, you can measure the frequency or period of therotating device. The DT9837A also provides the ability to accurately measure the time between the tachometer edge and thenext A/D sample or between the A/D sample and the next tachometer edge, so that you can precisely correlate A/D data withrotation data. For example, assume that you want to correlate A/D sample X from analog channel 0 to an angular position of
the rotating device. This can be accomplished by using a tachometer signal that always occurs at the top, center position of
the rotating device as a reference and measuring the time between the tachometer signal and the next A/D sample (Y). Since
you know the frequency of the A/D sample clock (50 kHz, in this case), you know when A/D sample X occurred in relation
to A/D sample Y (t2 = 1/50 kHz x num samples from Y to X). By using the Tachometer Counter 1 to measure the time (t1)between the tachometer signal and A/D sample Y, you can calculate exactly where A/D sample X occurred in time from thetachometer signal (result = t1 + t2). Given the rotation speed of Tachometer Counter 0, you can then calculate the angular
position of A/D sample X• A flag (called Stale) indicating whether or not thedata is new. If the Stale flag is set as Used (thedefault value), the most significant bit (MSB) of thevalue is set to 0 to indicate new data; reading thevalue before the measurement is complete returns
an MSB of 1. If the Stale flag is set to Not Used, theMSB is always set to 0. On the DT9837 module, theMSB is always 0 (not used).
When the operation is started, the internal 12 MHz
counter starts incrementing when it detects the firststarting edge of the tachometer input and stops
incrementing when it detects the next starting edgeof the tachometer input. When the measurement iscomplete, the counter/timer remains idle until it is read.
On the next read, either 0 or the current value of thetachometer input (from the previous measurement
operation) is returned depending on the module and theControl Panel settings, described above, and the next
operation is started automatically.

(508) 946-5100

The software automatically synchronizes the value of thetachometer input with the analog input measurements,
so that all measurements are correlated in time.

Phase Measurements – Tachometer Counter 1
On the DT9837A and DT9837B modules, users canmeasure the phase of the tachometer input in relation to
the A/D sample by reading tachometer counter 1.
An internal 48 MHz clock (with 21 ns resolution) is used
to calculate the measurement, which allows you toprecisely correlate tachometer measurements with theanalog input data.

Gate Input Features• Analog threshold trigger – This trigger source issupported on the DT9837A and DT9837C modules.

The DT9837A-OEM module provides a 4-pin gate input
connector for connecting a TTL gate input signal.
The DT9837B module provides a BNC connector forconnecting a gate input signal.

For the DT9837A module, an analog threshold
trigger event occurs when the signal attached toanalog input channel 0 rises above a user-specified
threshold value. Using software, specify the trigger
source as a positive threshold trigger, the threshold
trigger channel as analog input channel 0, and thethreshold level as a value between 0.2 V and 9.8 V.

Users can read the value of gate counter 2 to measure
the time between the following signals:• Completion of the A/D sample to the rising or fallingedge of the gate input signal• Rising or falling edge of the gate input signal to therising or falling edge of the gate input signal, which
you can use to determine the pulse width of thegate signal• Rising or falling edge of the gate input signal to thecompletion of the A/D sample

For the DT9837C module, the analog threshold
trigger event occurs when the signal attached to a
specified analog input channel in the analog input
channel list rises above a user-specified thresholdvalue. Any of the analog input channels can be usedas the trigger. The threshold value is programmable(±10 V for a gain of 1 or ±1 V for a gain of 10).

Analog Output Channels

Triggering Acquisition on Multiple Modules

The DT9837, DT9837A, and DT9837C modules support
one 24-bit analog output channel. Note that on theDT9837A module, you can read back the value of theanalog output channel through the analog input channel
list. The DT9837 and DT9837A modules provide a twopole, 10 kHz Butterworth filter to prevent noise frominterfering with the output signal. The analog output
channel powers up to a value of 0 V ±10 mV.

You can start acquisition on multiple modules byconnecting all modules to a shared external trigger
input. When triggered, the modules start acquiring dataat the same time. Using this connection scheme, themeasurements of one module may not be synchronouswith the measurements of another module due to logic
delays in the clocking and USB circuitry.

The DT9837 and DT9837A can output bipolar output
signals in the range of ±10 V, with a gain of 1. The
DT9837C module can output bipolar output signals in therange of ±3 V, with a gain of 1.

Synchronizing Acquisition on Multiple DT9837A,
DT9837B, or DT9837C Modules
DT9837A, DT9837B, and DT9837C modules provide an
RJ45 (LVDS) synchronization connector that you can use
to connect and synchronize multiple DT9837A, DT9837B,
or DT9837C modules. In this scheme, one module is themaster and the other modules are slaves. You specify
the synchronization mode (master, slave, or none) of the
RJ45 connector using software.
When configured as a master, the RJ45 synchronization
connector outputs trigger and clock signals. Whenconfigured as a slave, the RJ45 connector accepts trigger
and clock signals from the master; you cannot use the Ext
Trig BNC connector or the analog threshold trigger on
the slave module in this configuration. When configured
as none (the default mode), the DT9837A, DT9837B, orDT9837C module uses the USB clock instead of the RJ45
synchronization connector. The synchronization moderemains set until changed or until the application exits.

QuickDAQ with Advanced FFT Analysis Option.

Key Features

When synchronizing multiple modules, start the slave
modules before starting the master module. When themaster module is triggered (using any of the supported
trigger sources), both the master and the slave modules
start acquiring data at the same time (within one A/D
conversion of the clock). Note that you can set the clock
rate to be the same or different on each module. Whenacquisition is stopped on the master module the slaves
continue to run and return data until the analog input
subsystem is stopped on the slave modules.
