10. 3500 Quick Start User Manual 13 Basic Operation Probe Input The probe is electrically protected against static voltage However if you apply voltages above its design limits you may damage the probe tip amplifier The limits are shown in the graph on the following page See Figure 1 on page 15 Operating Voltage Input Range The operating voltage input range is the maximum voltage that you can apply to either of the input pins with respect to earth ground without exceeding the linear input range of the amplifier A signal that is outside this range if applied to either probe input can lead to an erroneous output waveform even if the differential input range is met Differential Mode Signal Range The differential mode signal range is the maximum voltage difference between the and input pins that the probe can accept without distorting the signal The distortion from an input signal that is too large can result in an erroneous measurement Common Mode Signal Range The common mode input voltage is the average of the voltage on the and input pins with respect to ground The common mode voltage input range is determined by both the operating voltage input range and the amplitude of the applied differential signal The peak signal applied to either input pin should not exceed the operating voltage input range so the common mode voltage input range is equal to the operating voltage input range reduced by one half the amplitude
