32 Keysight InfiniiVision 2000 X-Series Oscilloscopes User's Guide1 Getting StartedThe trigger source is selected by looking for the first valid waveform starting withexternal trigger, then continuing with the lowest number analog channel up to thehighest number analog channel, and finally (if digital probes are connected) thehighest number digital channel.During Auto Scale, the delay is set to 0.0 seconds, the horizontal time/div (sweepspeed) setting is a function of the input signal (about 2 periods of the triggeredsignal on the screen), and the triggering mode is set to Edge.Compensate Passive ProbesEach oscilloscope passive probe must be compensated to match the inputcharacteristics of the oscilloscope channel to which it is connected. A poorlycompensated probe can introduce significant measurement errors.1 Input the Probe Comp signal (see “Input a Waveform" on page 29).2 Press [Defaul t Setup] to recall the default oscilloscope setup (see “Recall theDefault Oscilloscope Setup" on page 29).3 Press [Auto Scale] to automatically configure the oscilloscope for the ProbeComp signal (see “Use Auto Scale" on page 30).4 Press the channel key to which the probe is connected ([1], [2], etc.).5 In the Channel Menu, press Probe.6 In the Channel Probe Menu, press Probe Check; then, follow the instructionson-screen.If necessary, use a nonmetallic tool (supplied with the probe) to adjust thetrimmer capacitor on the probe for the flattest pulse possible.On the N2862/63/90 probes, the trimmer capacitor is the yellow adjustment onthe probe tip. On other probes, the trimmer capacitor is located on the probeBNC connector.
