 Dear
Colleague,
It's very nearly June and you may already be thinking of
taking a summer break! Memories of last season's seemingly endless
snowfall have finally turned to thoughts of the beach and the smell of
sunblock! Our spring lasted about four days and now the trees have
bloomed and flowers are profuse... as are the new products and news at
Saelig, so take a look below.

High-Speed,
High-Capacity Programmable DC Electronic Load Series
|
|
 The PEL-3000 Series of single-channel
programmable DC electronic loads from GWInstek offer high-speed slope
and high power capacity to meet SPS (SMPS), DC - DC power converter,
Hybrid Electric Vehicle and other battery testing needs. With 0.01mA
current resolution and 16A/us current slew rate, power supply
characteristic tests can be performed with accuracy, stability, speed,
and over a wide power range. The PEL-3000 Series Electronic Loads
operate from 1.5V to 150V and have seven operational modes: CV
(constant voltage), CC (constant current), CR (constant resistance), CP
(constant power), CC + CV, CR + CV and CP + CV. In the CC and CR mode,
this versatile test tool can simulate a variety of sequenced dynamic
load characteristics, with specified load currents, up/down slopes,
current levels, durations, and other parameters to suit any load tests
needed. In Constant
Current Mode the load units will sink the amount of
current programmed; regardless of the voltage, the current will stay
the same. In Constant
Resistance Mode, set as resistance conductance, the
unit will maintain a constant resistive load by varying the current. In
Constant Voltage
Mode, the unit will maintain a preset fixed voltage
level. In Constant
Power Mode, the unit will maintain a constant power
level by varying the current. Via sequence editing, arbitrary
test output waveforms from the memory function can be set from the
front panel without connecting with a computer.

Raspberry Pi
Drivers for Pico's DrDAQ Data Logger
|
|
Raspberry Pi® is
the tiny computer that is making a big name for itself. Originally
designed as an inexpensive computer for kids to use to develop their
programming skills, this ARM GNU/Linux-based computer is rapidly becoming
the choice for "kids" of all ages. Pico's USB DrDAQ Raspberry Pi driver allows
you to use the USB DrDAQ Data
Logger with a Raspberry Pi. C++ example code is
included.

Independent reviews of Pico PS6403D
and PS2205A Oscilloscopes
|
|
Electronics blogger Colin O'Flynn has posted a detailed review of the recently-released PicoScope 6403D, with links to even more
detailed information on his YouTube channel. The scope belongs to the PicoScope 6000 Series, a range of
four-channel USB oscilloscopes with bandwidths from 250 to 500 MHz, 5
GS/s sampling, built-in arbitrary waveform generator and USB 3.0
interface.
Here are some of the features covered:
- Equivalent-time
sampling (ETS) mode - how to improve timing resolution to as little
as 20 ps
- How to
evaluate the frequency response of your scope
- Advanced
triggering - including pulse width triggers and the buffer overview;
extremely long but accurate trigger delays
- Serial
decoding with overlay of analog and digital data
- Arbitrary
waveform generator
- Using the
SDK - with an experimental Python interface
- Comparison
with competing scopes
PicoScope 2205A
A new independent review of the PicoScope 2205A by the
RoadTest Group scored it 10/10 in all six categories: performance,
specifications, software quality, ease of use, support materials and
price! This very detailed review answers questions about the scope,
including: understanding the specifications, comparison with other
manufacturers, teardown, PicoScope software, data logging with PicoLog
and tests in time and frequency domains. Read "PicoScope 2205A Review" by Gough Lui.

Versatile USB-I2CI/O Board for Easy Access to I2C
Peripherals
|
|
Ideal for integrating into equipment with your existing or
planned application software (e.g. manufacturing test set-ups) where
you know that only your own software will suit your needs and you must
have a reliable interface board. USB-I2CIO
provides long-life hardware, a simple API, and rock solid firmware, dll,
and driver (this is where most other I2C boards fall down). All for
a very reasonable price, with custom support available too. This
board is used by manufacturers around the world.

Lab Equipment for Universities and
Schools
|
|
Now is the time of year that university lab managers are
planning to upgrade and increase their equipment and capabilities.
Here are some of the products that we support and make available to
schools, colleges, and universities, but may be of interest to all our
colleagues too:
Best Priced Oscilloscopes from Rigol, Owon and GW Instek. We have an extremely broad
scope selection from manufacturers all over the world - from low-end scope-in-a-probe devices, to 6 instruments-in-1 toolbox essentials, to
high-end 16-bit 12GHz TDR units; from standalone,
economical LCD scopes, to sophisticated 4-channel bench-top 'workhorses';
educational starter scopes that include teaching experiments, to high-end
mixed signal scopes with logic analysis capabilities for sophisticated
glitch triggering and deep memory depth searching for rare
events. Our Syscomp Educational Oscilloscopes also
have associated training materials.
RF Test - We sell 3/6GHz Spectrum
Analyzers with tracking generators, 3GHz handheld spectrum analyzers, RF
signal sources and signal quality analyzers, USB RF test modules, as well
as EMI-proof enclosures. We also offer a special educational RF Trainer Bundle.

Troubleshooting on the Move
|
Today's engineers and technicians face increasingly
complex and critical troubleshooting tasks. Designs that work fine in the
lab can sometimes fail in the field, causing customer dissatisfaction,
lost production, expensive repair bills and, sometimes, safety concerns.
With the customer impatient to get their system fixed as rapidly as
possible there is huge pressure to troubleshoot and fix problems quickly
and accurately. A new article on EE Times Europe's Design Center explains
how you can use PicoScope
2200A and 5000 Series oscilloscopes to debug some common
field-failure problems.

 This month marks 50 years since the
invention of BASIC, the simplified programming language that made
computing accessible to everyone. In 1964, John G. Kemeny and Thomas E.
Kurtz designed the original BASIC language at Dartmouth College in New
Hampshire. "People who absolutely never would have engaged with the
computer before were now engaging with computers on campus," Dan
Rockmore, a Dartmouth mathematics and computer science professor, told NPR in a recent interview. Rockmore also recalled
his first encounter with BASIC as a high school student: "I'm almost
sure that I wrote a program to play poker."
