INTERVIEW
PULSE
Oscium creates test equipment that utilizes the intuitive
features and touchscreen technology of mobile devices
like the iPad and iPhone. Founded by brothers Matt and
Bryan Lee in January of 2010, Oscium existed for an entire
year before releasing its irst product. During that year, the Oscium
engineering team was developing and ine-tuning its irst product--the iMSO
scope--in its Oklahoma City ofices. The company has since expanded and
has recently won multiple design and engineering awards for their WiPry
family of products.
We spoke with Matt Lee, the Co-founder and Technical Team Lead at
Oscium, about the company’s growth, why they targeted mobile devices for
their test equipment products, and why he believes that Oscium is paving the
way for the future of test equipment.

anywhere. It’s small enough to it in your
pocket making it easy to use in the ield. The
scope uses the battery on the iPad so no
additional charge is needed. We are always
trying to bring our products to the next level
to give our customers exactly what they
need.
Could you give us an overview of
Oscium’s current products?
Oscium’s iMSO-104 was recognized as one of the
100 most technologically signiicant products of
2012 by the editors of R&D Magazine. Oscium’s
mobile-friendly oscilloscope was awarded for
merging the test equipment industry with the
smartphone and tablet industries.
In 2011, we released iMSO-104, our mixed
signal oscilloscope for iOS. The app is
downloaded through the Apple App
Store. You can then plug our hardware into
your iPad, iPhone, iPod and you have an
oscilloscope with one channel of analog
and four digital channels. This product
required us to rethink how test equipment
works so it could function on our platform.
We’ve gone through several iterations of our
software to make it more intuitive. We want
it to be so simple that anyone can pick it up
and understand how it works.
How do you go about making
software improvements?
The platform we have allows us to push
software updates quickly. If you look at the
product, we’ve made three signiicant UI
changes, almost entire rewrites. I think we’ve
honed in on a platform that is user friendly. It
is easy to navigate and allows easy access
to items you want. We’re always looking to
improve our products.
on the whole process. I would rather be hands-off and let creativity
lower instead of trying to drive creativity by minutes and increments.
At the same time it is important to have weekly meetings and
updates on progress to make sure we are goal oriented. Finding the
right balance can be somewhat challenging.
Our other product is a spectrum analyzer and
dynamic power meter, which we call WiPry-
Combo. There are two modes of operation.
One is a spectrum analyzer which gives you
a view of the 2.4-2.5 GHz ISM band. The
other is a dynamic power meter. Our power
meter is very different from the typical power
meters you see in the marketplace. It allows
you to look at the time usage, duty cycle
and on/off times from 100 MHz all the way to
2.7 GHz. The WiPry family is divided into two
products. We have a spectrum analyzer for
the IT professional called WiPry-Spectrum.
LogiScope Logic Analyzer or the iPad
What’s the secret to having an innovative DNA?
How has the shift to the lightning
connector affected your business?
I try to look at products differently than everyone else. I try to ask
myself not just how can it be changed, but how can it be improved.
Sometimes the change is small. Sometimes it is big. It just needs to
be approached from a different perspective. Our team tries to
keep the needs of the customer paramount. This approach is really
important when you are doing product development, and it’s harder
than it looks. There are plenty of people that think they can make a
product but there are many failures out there. Businesses fail all the
time. It’s very important that you have a good understanding of your
customer and what they actually need.
Initially, it was signiicant because there was
no clarity around whether 30-pin accessories
would work with the new connector. But
now we’ve been able to test and verify that
all of our products work with the lightning
adapter. We are fully compatible with all of
the newer iOS products.
With LogiScope, another product, we made
a really big advancement. It contains a
CPLD that does the data capture and also
includes sophisticated triggering options.
What we are ultimately trying to do with
our products is push the limits of low-power
solutions. One of the things we like about our
current platform is portability. You can pull
out your oscilloscope or your logic analyzer
What is your management style?
Originally, I preferred to be a heads-down
engineer, but now my role is to guide the
direction of our team. I’ve learned that
it is important to be able to do both. If
you are only a manager, you can’t really
communicate well with your engineers. And
if you’re only an engineer, you risk missing
the big picture. You need to be a little bit of
both; you need to be well-rounded.
“What we are ultimately trying to do
with our products is push the limits of
low-power solutions. One of the things
we like about our current platform
is portability. You can pull out your
oscilloscope or your logic analyzer
anywhere. It’s small enough to it in
your pocket making it easy to use in
the ield.”
iMSO-104 Mixed Signal Oscilloscope for the iPad
As we started producing more products,
my bandwidth was being decreased so it
made sense for us to hire more people and
to let them run with certain parts of projects.
This shift in thinking has added tremendous
value. We are a highly functioning team.

Bryan Lee, President & Matt Lee
What is your target market for your products?
Our customer is the next generation of inventors. This includes
educators, on-the-go technicians, and hobbyists. For us, education
is the key. As the younger generation comes up, touch is what they
know. A child can learn to use a tablet and smartphone before they
can learn to talk. We try to design products which it this simple and
intuitive model.

Have you had any upside surprises with Oscium?
Optocouplers are the only isolation devices that meet or exceed the IEC 60747-5-5
International Safety Standard for insulation and isolation.
Stringent evaluation tests show Avago’s
optocouplers deliver outstanding performance on essential safety and deliver exceptional High Voltage protection
for your equipment. Alternative isolation technologies such as ADI’s magnetic or TI’s capacitive isolators do not deliver
anywhere near the high voltage insulation protection or noise isolation capabilities that optocouplers deliver.

Even though I thought our mixed signal oscilloscope was a cool
product, I was surprised at how well it was received. The Apple
hardware gave us the ability to do things no one else in the industry
was doing. Multi-touch and pinch-to-zoom make setting up and
capturing the event easy because you are actually looking at the
event.
We did a video with the punch line ‘count the hairs on your bug.’ This
example drives home my own surprise at how these capabilities came
together. Marrying the intuitiveness of the platform transformed the
experience. Once someone has picked up our tool and used it, they
love it. I still have a benchtop scope on my desk, and it’s great when
I need to look at faster signals. But when I want to look at something
quick to verify the signal, our scope works perfectly, and my tablet
is always out for email and messaging. I can just plug it in and go. It
makes the tablet interface universal. We’re adding test equipment
abilities to an already ubiquitous interface.
