The new PicoScope 4226
and 4227 represent
the sixth generation
Powered from the
USB port and
including a built-in
generator, these scopes contain everything you need to
make accurate high-speed measurements. Just plug one
into a laptop or desktop computer, run the software
supplied, and get to work.
The latest PicoScope 4000 Series oscilloscopes have
two 12-bit input channels with a bandwidth of 50 MHz or
100 MHz, allowing them to capture detailed waveforms
for production testing, scientific analysis, and electronic
design and debugging. The third input is a dedicated
external trigger. The fourth connector is the output of the
signal generator which allows you to load an arbitrary test
signal, draw your own waveform using the graphical
editor, or use one of the six preset waveforms.
The PicoScope 4227 can sample at rates up to 250
MS/s, and the PicoScope 4226 up to 125 MS/s. Both
models have a deep 32 megasample buffer memory that
continued from page 26
enables the maximum sampling rate to be used even on
slow timebases. The buffer can hold up to 10,000
waveforms which are displayed in a pop-up navigator
window for easy access.
A fully enabled version of the PicoScope oscilloscope
software is included in the price. PicoScope for Windows
offers a wide range of advanced functions such as mask
limit testing, alarms, serial data decoding, programmable
low-pass filtering, math channels, reference waveforms,
Digital Color and Analog Persistence display modes, and
XY mode. The advanced trigger types include pulse width,
window, interval, dropout, and runt pulse.
The units include probes and a carrying case. Along
with all of the features listed above, unlimited free
software updates are available from their website, along
with free technical support. There is a free five-year parts
and labor warranty against manufacturing faults.

The model 5491B multimeter is unsurpassed for
applications in education, service and repair,
manufacturing, or any application where affordable,
accurate, and reliable measurements are needed.
The 5491B offers an accuracy of 0.02%, a digital dual
display for viewing two measurements simultaneously, a
fast measurement rate of up to 25 readings per second,
threshold settings for quick Pass/Fail testing, plus the
ability to download measurement values to a computer
via USB or RS-232 interfaces using the SCPI protocol.
The unit’s AC+DC capability captures any DC effects
within the measured voltage or current for the most
accurate results. Housed in a rugged case for easy
stacking, the front panel of the 5491B has a bright display
and tactile pushbutton control with easy-to-follow second
This workhorse instrument provides all expected
measurements of AC and DC voltage to 750V and
1,000V, respectively, AC and DC current to 20A,
resistance, frequency, and continuity test. There are also
built-in math functions of REL (relative) for offset
measuring, Max/Min for capturing highest and lowest
values, dB, dBm, Data Hold, and Compare.
