5000D Series oscilloscopes
Mask limit testing
Mask limit testing allows you to
compare live signals against known
good signals, and is designed for
production and debugging environments.
Simply capture a known good signal,
generate a mask around it and then use
the alarms to automatically save any
waveform (complete with a time stamp)
that violates the mask. PicoScope will
capture any intermittent glitches and show a failure count in the Measurements window
(which you can still use for other measurements). You can also set the waveform buffer
navigator to show only mask fails, enabling you to nd any glitches quickly.
Mask les are easy to edit (numerically or graphically), import and export, and you can
simultaneously run mask limit tests on multiple channels and in multiple viewports.
Math channels and lters
With PicoScope 6 you can perform a variety
of mathematical calculations on your input
signals and reference waveforms. Select
simple functions such as addition and
inversion, or open the equation editor to
create complex functions involving lters
(lowpass, highpass, bandpass and bandstop
lters), trigonometry, exponentials, logarithms,
statistics, integrals and derivatives.
Display up to eight real or calculated channels
in each scope view. If you run out of space,
just open another scope view and add more.
You can also use math channels to reveal new
details in complex signals, for example graphing the changing duty cycle or frequency of
your signal over time.
Custom probes
The custom probes feature allows you to correct for gain, attenuation, offsets and
nonlinearities in probes, transducers and other sensors, and to measure quantities other
than voltages (such as current, power or temperature). Denitions for standard Pico-
supplied probes are built in, but you can also create your own using linear scaling or
even an interpolated data table, and save them for later use.
Alarms
You can program PicoScope to execute actions when certain events occur.
The events that can trigger an alarm include mask limit fails, trigger events and buffers
full.
PicoScope’s actions include saving a le, playing a sound, executing a program and
triggering the arbitrary waveform generator.
Alarms, coupled with
mask limit testing,
help create a powerful
and time-saving
waveform monitoring
tool. Capture a known
good signal, generate
a mask around it and
then use the alarms to
automatically save any
waveform (complete
with a timestamp) that
does not meet your
specications.
