  1. When sweeping frequency in the network or impedance analyzers, the default number of samples is 100, but this usually results in awkward values, as it corresponds to 99 steps (fencepost error). It would be better to make the default be 101 samples. It might also be nice to have a way of setting the step size, rather than the number of samples. For linear spacing, this is just a value in Hz (for example, 10Hz–100Hz in steps of 1Hz is 91 samples). For logarithmic spacing, specifying a ratio is awkward, but steps/decade is simple. For example, the 1 kHz–1 MHz at 50 steps/decade is 151 samples). I'm usually more interested in controlling the steps/decade than the total number of samples.
