A question was recently posed regarding the grounding conditions of a BNC type input. The shield or outer of a BNC cable or connector is not connected to the chassis or ground. What would happen if it was connected to ground?
When using an analogue channel input channel of a P8000, with a tachometer sensor, is it possible to utilise the tachometer processing functions as you would if you were using a tachometer input of the P8000?
For example could you display an RPM on an analogue channel?
When using an analogue channel it is possible to select, from the signal setup matrix, ‘Trigger Type’, with this option set to ‘Tacho’ and the ‘Trigger Level’ set to the voltage crossing threshold several features become available in terms of tachometer processing.
By selecting the above options the user will be able to use the ‘Digital Panel’ display type from the signal display and thus by selecting the ‘Speed’ option in the ‘Display Type’ drop down list an RPM will be available.
When analysing a waterfall or performing order analysis it is important to consider the frequency resolution or the frequency spacing.
There is often a desire to increase the resolution to finer and finer detail. But that is a process of diminishing returns, and actually fraught with danger. And that danger is waterfall smearing. Continue reading What is “waterfall smearing”?
