Keysight E5400-Pro Series Soft Touch User’s Guide 71Circuit Board Design 5Clock inputThe clock input to the E5402A and E5406A probe is differential. If yousupply a differential clock, you should select the “differential” option in theclock threshold user interface.If your system uses a single-ended clock signal, the clock input should beeither grounded or connected to a dc power supply. You may:• Ground the clock input and adjust the clock threshold from the userinterface to between -3V dc and +5V dc.Signal AccessLabels split across probesIf a label is split across more than one pod, this leads to restrictions intriggering. Refer to "Triggering with the Keysight 1675x and 1676x"(Keysight publication number 5988-2994EN) for more details.Reordered bitsIf bits need to be reordered within a label, this leads to additionalrestrictions in triggering. Specifically, equalities can be used to evaluatethe value of a label with reordered bits, but inequalities cannot be used.You may be able to avoid the need to reorder bits in a label by routingsignals to appropriate pins on the probe connector. Refer to "Triggeringwith the Keysight 1675x and 1676x" (Keysight publication number5988-2994EN) for more details.Half-channel 1.25 and 1.5 Gb/s modes (16760A only)In the half-channel 1.25 and 1.5 Gb/s modes, the 16760A analyzeraccesses only the even channels (0,2,4, etc.). In the Format user interface,only the even data bits will be connected to the analyzer.Note that in the 1.25 and 1.5 Gb/s half-channel mode, the clock inputscannot be assigned as bits in a label.E5386A Half-channel AdapterThe E5386A can be used with the E5405A-pro series differential soft touchprobe or the E5402A/E5406A-pro series single-ended probes to map thesignals from the PC board pads to the 16760A when operating inhalf-channel state mode.Artisan Technology Group - Quality Instrumentation ...
