| 摘要： | Ease of use has been one of the main driving factors behind PicoScope 7 and the new 4×25A Automotive scopes. Probe Mismatch is a feature that supports this. When you want to recreate a test by loading an already saved waveform, the Probe Mismatch feature will help you make sure that your PicoScope is configured to replicate that specific test. It will do this by notifying you if you do not have the "correct" probes connected to your scope. For this feature to work, the psdata file will have to have been saved with a 4×25A scope connected and with PicoBNC+ probes in use. Let's see it in action. In our example, we have used all four channels on a PicoScope 4425A to capture the secondary ignition event on one cylinder. We have used a mix of PicoBNC+ and BNC ignition probes. Channel A: PicoBNC+ Secondary ignition pick up Channel B: PicoBNC+ COP Probe Channel C: BNC Secondary ignition pick up Channel D: BNC COP Probe If I load this file with any automotive scope connected, the waveform will be displayed as expected (see image below). To replicate the test, we need to manually configure the probes (for each channel) to match those used in the original capture. If we are using a 4423 or 4425, we would have to use the BNC equivalent of the PicoBNC+ probes connected to channels A and B in the above image. |
