The Picoscope 4424 and 4224 offer both a high resolution (12 bits) and a high DC accuracy (1%) making them an excellent choice for noise, vibration, precision electronics and mechanical analysis.
The optional IEPE interface (see below) allows for the direct connection and powering of industry standard accelerometers and microphones.
The PicoScope 4224 and 4424 are 12-bit oscilloscopes that offer 16 times more vertical resolution than traditional 8-bit oscilloscopes (4096 vertical levels vs 256). The example shows how with a 12-bit oscilloscope (blue trace) you can zoom in to reveal details of the signal that are not visible on an 8-bit oscilloscope (black trace).
As well as the high vertical resolution, the 32 million sample buffer memory ensures a high horizontal resolution as well. You can collect long detailed captures without the sampling rate dropping.
Once you have seen high-resolution waveforms on a high-resolution PC monitor you will never want to use a traditional benchtop oscilloscope with its small display again.
As well as improved oscilloscope traces, high resolution offers big benefits when performing spectrum analysis offering an additional 20 dB dynamic range on the spectrum over 8-bit oscilloscopes. Signals that were previously hidden in the noise floor are now clearly visible and the spectrum becomes a powerful tool to track down the causes of noise.
The PicoScope 4224 is available with an optional internal IEPE (integrated circuit piezoelectric) interface allowing for the direct connection and powering of industry standard accelerometers and microphones.
When disabled the channels can be used as normal oscilloscope inputs. When IEPE is enabled (each channel has independent control via software) the input is AC coupled and a 24 V, 4 mA signal is output to power external sensors.
The high resolution and dynamic range of the 4224 makes it ideal for use with accelerometers and microphones. Having the IEPE interface built in makes for a compact, portable solution.
