Introduction
Sometimes, it is difficult to run LAN wires to a location from which you want to collect data. Placing
a data acquisition system near the location from which you want to collect data may be possible, but
providing wired LAN access may prove to be too difficult. Using a wireless connection to the data
acquisition system solves this problem. The Keysight Technologies, Inc. 34972A data acquisition/
switch unit comes in a compact package that includes LAN capability. If you combine its LAN capabil-
ity with a wireless router, such as the Sapido RB-1632 mobile router, you will have wireless access to
a powerful and flexible data acquisition system. This measurement brief provides the steps you need
to take to turn your 34972A into a wireless data acquisition system with the help of a Sapido RB-1632
mobile router.
Snapshot: Acquire data from a remote, noisy location
Engineers working on the design of new heating, ventilation, and air conditioning (HVAC) systems are
frequently faced with the challenge of collecting data from equipment that is located in a remote part
of an industrial site such as on a rooftop or in a basement. The HVAC systems located in these areas
can also create substantial acoustic noise, making the area surrounding the equipment an undesirable
place to work. Additionally, these locations often do not have wired LAN installed nearby, making it
difficult to remotely access any collected data. The engineers must still evaluate their new designs by
collecting various temperatures, DC voltages, and AC voltages from their HVAC system.
The Keysight 34972A data acquisition/switch unit solves their problem; it is an ideal solution for
making temperature and voltage measurements. When evaluating new HVAC systems, design
engineers can take advantage of the compact size and adequate channel
count. By adding a wireless connection to the 34972A, the engineers can
easily control the data acquisition unit and access their data from a more
environmentally friendly location. The engineers can use a Sapido mobile
router to add wireless capability to the LAN-enabled 34972A and collect
the evaluation data they need without adding wired LAN cables or working
close to the noisy equipment.
