*Some of these frequencies are not listed in the sampling frequency selection combo box of the Multi-Instrument software. You need to stop the oscilloscope, enter the sampling frequency value directly into that combo box and then set the number of sampling channels to single, if you need to use these sampling frequencies.
**Under these sampling frequencies, adjusting the trigger mode, trigger source, trigger edge, trigger level, trigger delay will have no impact on the sampling.
