Page 58: Threshold Settings
® Waveform setup R&S RTB 2 Vertical setup Deskew compensates delay differences between channels caused by the different length of cables, probes, and other sources. Correct deskew values are important for accurate triggering. Signals that are routed over lines with different lengths have a dif- ferent propagation delay.
Page 59: Label Settings
® Waveform setup R&S RTB 2 Vertical setup Threshold A threshold is used for digitization of analog signals. If the signal value is higher than the threshold, the signal state is high (1 or true for the Boolean logic). Otherwise, the signal state is considered low (0 or false) if the signal value is below the threshold.
Page 60: Probes
5.4 Probes With R&S RTB 2, you can use voltage and current probes that have a BNC connector. To get correct measurement results, always set the appropriate attenuation factor and the unit in the "Probe" menu.
