Introducing the TSR AIR
The TSR AIR is a small high-performance, low power, data logger that can autonomously
recognize and capture long and short duration events via built-in sensors.
The primary use for the TSR AIR is to collect data in various scenarios while mounted to the
interior or exterior of a test article. Captured events can be started by crossing sensor
thresholds, or by an external trigger. The device can also collect events based on a date
and time or time interval. The device will stay in a low power state when not in use. The
units can be daisy chained to share DTS bus signals and synchronization information.
•Shock rated to 500 g for dynamic testing environments.
•Sample rates up to 20,000 sps on 12 channels simultaneously (record in place or
data streaming).
•Real-time data streaming up to 20,000 sps per channel.
•3-channels of low g acceleration, 3-channels of high g acceleration, 3-channels of
angular rate, temperature, pressure, and humidity.
•Ethernet PTPv2 communications (IEEE1588) easily supports synchronization of
hundreds of channels.
•LED indicators for system and power status.
Embedded Sensors
The TSR AIR contains independent embedded sensors for low g acceleration, high g
acceleration, angular rate, temperature, pressure, and humidity.
Sensor Sample Rates
The TSR AIR uses the sample clocks on the embedded sensors to collect data at their native
rates and then sub- or super-samples that data to match the TSR AIR system rate when
storing in flash memory. At a given rate, each individual three axis sensor will record at its
own independent rate. For example, with the TSR AIR set to sample at 10,000 sps, the low
g sensor will record at 25,600 sps, the high g sensor will record at 5,120 sps, and the ARS
will record at 6,400 sps. See the table below for more details.

Sensor Bandwidths
Like the sample rate considerations in the section above, each individual embedded sensor
has its own bandwidth configuration at a given TSR AIR system sample rate. For example,
with the TSR AIR set to sample at 10,000 sps, the low g sensor will have a bandwidth of
1 kHz, the high g sensor will have a bandwidth of 640 Hz, and the ARS will have a bandwidth
of 178 Hz. See the table below for more details.

Sensor Ranges
Each embedded sensor has its own measurement range capability.
Low G Acceleration
Can be configured to collect data at a range of 50 g, 25 g, 12 g and 6 g.
High G Acceleration
Can collect data at a range of 400 g.
Angular Rate Sensor (ARS)
Can be configured to collect data at a range of 2,000 deg/s or 250 deg/s.
System Connector All communications, control signals and input power are
provided via the 25-pin, micro-D system connector. Using a
TSR AIR Chain Module or other interface, multiple units can
be connected (daisy-chained) for hundreds of test channels.
Ethernet signals must be connected in series with a maximum cable length of ~10 m. (Cable
quality may affect maximum length and performance.) Control signals must be connected in
parallel. See Appendix A for pin assignments.
Time Synchronization
The TSR AIR supports Ethernet Precision Timing Protocol version 2 (PTPv2)
communications (IEEE1588). PTP (Precision Timing Protocol) provides standards for
precision clock synchronization for measurement and control systems via Ethernet network

TSR AIR User’s Manual March 2023

communications. Timing information is extracted from the network’s master clock and used
by the TSR AIR to adjust their internal (local) clock, providing precision timing for high
channel-count systems with a sampling synchronization better than 10 µs. Communication
is enabled after the initialization sequence has completed (~15 s after sufficient power and
ON signal is applied). (Note network congestion may slow IP address acquisition.)
Power Management
A good power source is of paramount importance. The TSR AIR should be powered from a
high-quality power supply.

The TSR AIR does contain an internal battery. Without external power applied, the TSR AIR
is in a hibernate state when not armed. When the unit is on (sufficient power and ON signal
applied), power consumption depends largely on whether the unit is armed.
Battery
The TSR AIR battery performance is dependent on its recording state. Please refer to the
table below for complete details.

Power-up and Power-down Procedures
When sufficient power is applied, the TSR AIR will reboot (on, idle and communication
enabled) if an ON signal is present. With power applied but the ON signal absent, the unit is
in an idle state. Power up (ON state) occurs in ~15 s, after which communication is enabled.
Power down of the unit is immediate upon removal of either the ON signal or external power.
Wait ~30 s before reinitialization.
LEDs
The TSR AIR has two LED indicators that show system and power status.

•When not armed, the LED will blink green when handling a command from the PC.
•For Active mode:
-When armed, the LED will go solid blue to indicate that it is waiting for an EVENT
signal or level trigger to occur.
-When the EVENT signal is received, the LED will turn red to indicate that it is
actively recording data.
-The LED will turn off when data collection has completed.

Data Memory Size
With 8 GB for 13000-60401 and 16 GB for 13000-60404 of flash memory available for data
storage, the TSR AIR can record ~277 minutes and ~555 minutes of data, respectively, at
the maximum sampling rate (12 channels at 20,000 sps). Since the recording capacity is
very large, it is generally best to limit sampling rates and event durations to the minimum
necessary to avoid large and cumbersome data files. Large files take longer to download
and may also be time-consuming to post-process or difficult to share. Use of the Region of
Interest (ROI) download can save a great deal of time if implemented properly.
Sampling Rates
User-selectable sampling rates are available from 100 sps to 20,000 sps.

With 8 GB for 13000-60401 and 16 GB for 13000-60404 available for data storage, there are
4,000 M samples for 13000-60401 and 8,000 M samples for 13000-60404 available
(1 sample = 2 bytes). To determine the maximum recording time, divide the number of
samples by the product of the sampling rate and the number of channels.

Basic Care and Handling
TSR AIR systems are precision devices designed to operate reliably in dynamic testing
environments. Though resistant to many environmental conditions, care should be taken not
to subject the units to harsh chemicals, submerge it in water, or drop it onto any hard surface.
WARNING:
Electronic equipment dropped from desk height onto a solid
floor may experience up to 10,000 g. Under these conditions,
damage to the exterior and/or interior of the unit is likely.
Your TSR AIR module is supplied with calibration data from the factory. DTS recommends
annual recalibration to ensure that the unit is performing within factory specifications. The
TSR AIR is not user-serviceable and should be returned to the factory for service or repair.
Shock Rating
The TSR AIR is rated for 500 g, 4 ms half-sine duration, in all axes.
Mounting Considerations
TSR AIR equipment should be bolted securely to the test article or dynamic testing device to
provide the best shock protection. Mounting methods and hardware selection should be
calculated to withstand expected shock loading and facilitate proper grounding. Check bolt
tightness periodically to ensure that the unit is securely fastened to the testing platform.
DTS strongly recommends that all equipment be properly grounded to minimize any risk of
data noise due to high-current transients. The test article or dynamic testing device should
be connected to earth ground. TSR AIR equipment should be grounded to each other and
bolted to the test article. DTS recommends checking continuity between the enclosures of
each unit to confirm resistance readings of <1 ohm.
Thermal Considerations
The TSR AIR is a low power device, and it is unlikely that self-heating will be an issue in real-
world testing if proper mounting methods are observed. Never mount the unit to a thermally
non-conductive surface like wood or plastic. ALWAYS use the TSR AIR with a heat sink if
you are not mounting the system to a structure that will serve this purpose. Should you have
any questions about using the TSR AIR in your environment, please contact DTS.
Environmental Rating
The TSR AIR is IP67 rated.
•6 (solid ingress) = totally protected against dust.
•7 (liquid ingress) = Protected against the effects of temporary immersion between
15 cm and 1 m. Duration of test 30 minutes.
