NI 9467 Overview
The NI-9467 is a stationary GPS timing module for C Series platforms. It provides
accurate timing and geographic location information to the C Series host, which
enables synchronization of C Series systems.
Start-Up Behavior
At start-up, the NI-9467 automatically begins determining its location through a
process known as self-survey. During the self-survey, the module computes a
location fix every second and averages the locations at the end to obtain a more
accurate location. Aer the self-survey, the NI 9467 no longer computes new
location fixes; it uses its known location and satellite signals to generate accurate
timing signals.
Like all GPS receivers, the NI-9467 requires GPS satellite ephemeris and almanac
data to compute accurate time and location. The ephemeris is detailed orbital
information about each satellite (where each satellite is expected to be at a given
time). The almanac data describes the general health of each satellite (for example,
the receiver must not use signals from satellites marked as unhealthy) and contains
coarse orbit information. The GPS satellites broadcast the ephemeris and almanac
data every 30 seconds. Therefore, it usually takes approximately 30 seconds for it to
receive the ephemeris and almanac data and start computing location and timing
fixes.
Status LED
The NI-9467 has a front panel LED to indicate status. The following table describes
the meaning of each LED pattern.
Conditions LED State
Normal operation Solid green
Performing survey Blinking green
Not enough or no satellites Blinking yellow

Note Although the module may not detect the presence of very low-
power GPS antennas, it can still function correctly. Note that the LED and
soware may report antenna error under these conditions, and if the
current consumed is close to the detection threshold the LED may flicker.
Refer to the Specifications section for more details.
Connecting the NI 9467
The NI-9467 has one SMA female connector on its front panel for a GPS active
antenna. The connector provides a DC voltage to power the antenna and also serves
as input for the GPS RF signal.
Installing the Antenna
Caution National Instruments recommends using a lightning arrester in
line with the GPS antenna installation to protect the NI-9467 and the C
Series system from possible damage and operators from injury in the
event of lightning.
The embedded GPS receiver in the NI-9467 requires signals from several satellites to
compute accurate timing and location. The more satellites available to the receiver,
the more accurately it can determine time and location. Therefore, the antenna
location should be such that it receives signals from the greatest number of
satellites possible. As the number of satellites visible to the antenna decreases, the
synchronization performance may also decrease. Choose the antenna location so
that the antenna has a clear view of the sky. There is no strict definition for a clear
view of the sky, but a suitable guideline is that the GPS antenna should have a
straight line of sight to the sky in all directions (360°) down to an imaginary line
making a 30° angle with the ground. Locations far from trees and tall buildings that
could block or reflect GPS satellite signals are best.
Maximum Cable Length
Maximum cable length depends on the GPS antenna gain and the cable’s loss per
unit of distance. National Instruments recommends a GPS signal strength of
© National Instruments 7
NI-9467 Getting Started

between -135 dBm and -120 dBm at the NI-9467 SMA input. GPS signal strength on
the Earth’s surface is typically -130 dBm. Targeting a signal strength of -125 dBm at
the SMA input, you can compute the maximum cable length as:
■Max_cable_loss = -130 dBm + antenna_gain - (-125 dBm)
■Max_cable_length = Max_cable_loss / (loss_per_unit_of_distance)
For example, if you use an active antenna with gain of 28 dB and RG-58 cable, which
has a rated loss at 1.5 GHz of about 0.8 dB/m (24.5 dB/100 ), the maximum cable
length you could use is:
■Max_cable_loss = -130 dBm + 28 dB - (-125 dBm) = 23 dB
■Max_cable_length = 23 dB / (0.8 dB/m) ≈ 29 m
Sleep Mode
This module supports a low-power sleep mode. Support for sleep mode at the
system level depends on the chassis 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 soware 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.
Notice that when the NI-9467 is in sleep mode, the GPS receiver is not powered and
stops tracking satellites. When the module exits sleep mode and power to the GPS
receiver is restored, the module goes through the normal power-up process, which
includes the ephemeris/almanac data acquisition and self-survey process.
Therefore, it can take approximately 30 seconds before usable timing and location
signaling can be generated. Refer to Start-Up Behavior for more information.
