Is a bug in your circuit design giving you the slip? Try this Keysight Technologies oscilloscope. It lets you see how voltage changes over time by analysing its waveform and bandwidth, making it a cinch to test your electrical circuit quickly. An integrated touchscreen means you can simply draw a box around a signal with your finger, and the oscilloscope will trigger on it in an instant. The instrument's update rate of one million waveforms per second keeps your signal behaviour in the picture so you can identify glitches at once.
