Sample rate, measurement time and trigger offset
Depending on the sample rate, the maximum demodulation bandwidths listed in the table can be
obtained during the measurement. The permissible value range of the measurement time and trigger
offset depends on the selected demodulation bandwidth. If the AF filter or the AF trigger are not active,
the measurement time enlarges by 20%.
