Debug Designs with the New HD3 Oscilloscope

Mariafaria

HD3 Oscilloscope

Join one of the HD3 oscilloscope launch events below. Register now.

With a new custom ASIC and a 14-bit ADC, the HD3 provides 4x the vertical resolution and 1/2 the noise floor of other general-purpose oscilloscopes, giving you a more accurate representation of the signal you’re measuring.

Learn how the custom chip technology behind our powerful new oscilloscope will help you debug in consumer electronics, power supply testing, and automotive.

Attend for a chance to win!

We’re giving away fun HD3 assembly kits to 178 lucky winners. This means you could be among the first to have an HD3 oscilloscope on your bench — built out of construction bricks!

This promotion is available only in specific countries. Entrants must be 18 years or older. For more information, see the terms and conditions.

    I wrote a Python bode plotter. Currently intended for MXO 4 (which has it's own internal bode plot function, but I wanted practise in programmability with the 'scope when I got it, so it was just an experiment).

    It would be easy to modify for any scope (internal or external signal generator) by changing the SCPI commands. 

    Also since it's in Python, it is easy to customize the chart output. I don't like charts with tiny numbers on the axes for instance.

    Plus there's a list of frequencies in the code, so it will only test at the desired ones.

    The code is not thoroughly tested (I don't know what it will do with very weak output, for instance). Also there's no phase calibration function currently, it is dependent on coax cable lengths for now for that!

    EDIT: Also technically not a 'bode plot'! don't know why it gets referred to as that, and no 'scope can generate that. So I called mine 'audio analyzer'.

    I'm sure it can - but it will be a software option.

    From the prices I've seen for basic serial comms decoders for this scope you'll be looking at an extra £1-2k.

    Mind you, I've looked at Bode plotters on a range of scopes and they range from OK at best to dreadful. The correlation with price charged is not good.

    Built in to the scope is handy but driven by some simple software in Python. VB or whatever will usually be much better.

  • Nice o-scope, enjoyed the EEVblog early preview.
