The Engineering Science Laboratories are named as Cerent Engineering Science Complex to honor the engineers from 'Cerent' (now part of Cisco) whose contributions were instrumental in founding the MS-CES program. The Cerent Engineering Science Complex consists of eight well-equipped state-of-the-art laboratories in the areas of communications, networking, photonics, microanalysis, electronics, computer-controlled instrumentation and software engineering.
These labs are part of the Electrical Engineering and MS-CES Programs and supported by many local industries and private funds. The goals and objectives of these labs are to (i) enrich classroom instructions with hands-on experience in the laboratories, (ii) provide cutting edge research and development facilities to the students and faculty of SST to do state-of-the art projects, applied research and fundamental research, and, (iii) act as incubators to develop new technology and applications. For a list of equipment in the labs, visit Equipment and Instruments in Laboratories. An overview of these labs is given below.

William Keck Microanalysis Laboratory (Salazar Hall 2009B)
The Microanalysis Laboratory consists of four major instruments at the present time:
- Hitachi Scanning Electron Microscope (SEM) (Salazar Hall 2009C)
The SEM instrument is configured to allow imaging of inorganic objects as well as the more difficult to prepare and analyze biological specimens. Magnification up to 300,000X is well within the range of the instrument. A sample holder allows us to maintain the sample temperature from -20C to +85C. In addition, to the traditional SEM functionality, this instrument is equipped with Energy Dispersive X-ray Analysis (EDX). We are able to collect full atomic elemental analysis on a per pixel basis of the entire SEM image. As such we obtain extremely magnified images while simultaneously measuring the elemental content of any portion of the image.
- Olympus confocal imaging system (Salazar Hall 2009D)
The confocal imaging facility is equipped with an Olympus FV300 laser scanning system attached to an Olympus BX61 upright microscope. This system has three lasers: Argon (488 nm), Red HeNe (633 nm) and Green HeNe (543 nm) allowing the utilization of a wide range of fluorescent probes for specimen analysis. The unique feature of this instrument is its ability to generate 3D confocal images of a variety of living and non-living biological materials. With the help of an SIS Biological Suite Imaging Software, the digital camera attached to the above microscope system allows researchers to gather and analyze high quality bright-field, dark-field, phase and Nomarski-DIC images of specimens.
- Pacific Nanotechnology Scanning Probe Microscope (SPM)(Salazar Hall 2009B)
The Pacific Nanotechnology SPM is a tool that allows us to measure the properties of atomic surfaces. Sometimes the SPM is referred to as an Atomic Force Microscope (AFM). The SPM or AFM is comprised of a very small and sharp tip, the point of which is only a few atoms in diameters. This tip is connected to a cantilever and is moved in a systematic way over the surface of the sample. The repulsive Van der Waals force between the tip and the sample results in the movement of the cantilever. That movement is imaged via a secondary laser system built into the instrument. Typical scan areas can vary from 100 nanometers(nm) X 100 nanometers up to 100 microns X 100 microns. A nanometer is 10-9 meters, while a micron is 10-6 meters. The height profile ranges from 0.1 nm to 100 nm. An instrument similar to this instrument recently certified the average roughness of the mirrors used in the new NASA x-ray telescope EXAFS.
- PHI Auger spectrometer (Salazar Hall 2009B)
The PHI Auger spectrometer is an instrument that allows us to measure the strengths of various atomic bonds in a particular specimen. The EDX instrument mentioned above allows us to determine the presence of a particular atomic element in a specimen. The Auger spectrometer then allows us to probe the chemical nature of the specimen more deeply.
Each of the above instrument probes a different aspect of a particular sample. Therefore, combination of these instruments is actually more important than any one instrument. In combination, we can learn/deduce key mechanism in the formation of the sample. For example, we can determine whether a thin film was evaporated or sputter deposited. We can deduce the ability of a thin film sample to withstand abrasion and predict how well it will withstand harsh chemical environments.
Networking Laboratory (Salazar Hall 2006)
This laboratory provides facilities for instruction and experimentation in computer networking. There are six identically equipped work areas containing hubs, switches, routers and computers that can be connected and configured for a wide range of networking experiments, such as, LAN, VLAN and WAN designs. Every computer can run a choice of operating systems, either Windows or Ubuntu, and each contains a variety of programming and networking tools for network analysis. There are easily reconfigured interconnections that connect the work areas to each other, to dedicated servers and to the Internet.
Senior Design Laboratory (Salazar Hall 2007)
The facilities in this laboratory support undergraduate engineering students in order to complete their capstone senior design experiments. Students enrolled in the Senior Design Project Planning/Implementation (EE492/493) have 24/7 access to the lab. A wide range of hardware and software development tools are available upon request to the students in this laboratory, including high-speed oscilloscopes, logic analyzers, function generators, pattern generators, power supplies, digital multimeters, spectrum analyzers, network analyzers, signal generators, wireless testing instruments, STE series Shielded Test Enclosures, and more.

In addition to the above items, the room has a small refrigerator, microwave and a kettle for highly motivated students!
Software Engineering Laboratory (Salazar Hall 2008)
This laboratory provides computers and software that support a range of software projects as well as undergraduate and graduate instruction in software engineering. For each computer there is a choice of standard operating systems and a selection of software including compilers, databases, and tools for graphics. The lab is configured to be used either for projects or for classroom instruction. One computer is connected to a large screen data projector and wireless keyboard and mouse for convenient instruction. All computers are networked to the Internet.
Electronics Laboratory (Salazar Hall 2003)
The electronics laboratory is equipped with function generators, oscilloscopes, logic analyzers, multimeters, power supplies, networked computers, soldering stations and necessary breadboards and electronic components. In addition, it is equipped with Cadence, Keysight, Matlab and NI software packages.
The lab is used to provide fundamental as well as advanced instruction to undergraduate and graduate students in digital and analog electronics, VLSI design, embedded systems and computer architecture. In addition, students use these facilities to carry out their design projects and research.
This facility is not part of Cerent Engineering Science Complex but is available to all students. The SSU Makerspace is a place to dream, make, and innovate. SSU students, faculty, and staff are invited to explore digital fabrication, prototyping, and a wide range of technology to transform idea to reality. All disciplines and skill sets can experience new technologies through workshops, experimentation, and free-play. By providing the tools and ingredients the hope is to encourage creativity and inquiry, and to facilitate cross-disciplinary collaboration.
