Preface
Manual Conventions
This manual uses certain conventions that you should become familiar with.
Modules Throughout this manual, any replaceable component, assembly, or part of the waveform analyzer is referred to generically as a ªmodule.º In general, a module is an assembly (circuit board), rather than a component (resistor or integrated circuit). Sometimes a single component is a module; for example, each ejector handle is a module.
Safety Symbols and terms related to safety appear in the General Safety Summary near the front of this manual.

2The limits given are for the ambient temperature range of 0_ C to +30_ C. Reduce the upper bandwidth frequencies by 5 MHz for each _C above +30_ C. The bandwidth must be set to FULL.
3Rise time (rounded to the nearest 50 ps) is calculated from the bandwidth when Full Bandwidth is selected. It is defined by the following formula:
Rise Time (ns) = 450 BW (MHz)

4GND input coupling disconnects the input connector from the attenuator and connects a ground reference to the input of the attenuator.
5The AC Coupled Lower Frequency Limits are reduced by a factor of 10 when 10X passive probes are used.
6The sensitivity ranges are 10 mV to 100 V full scale, switching in a 1±2±5 sequence of coarse settings. Between these coarse settings, you can adjust the sensitivity with a resolution equal to 1% of the more sensitive coarse setting. For example, between the 500 mV and 1 V ranges, the sensitivity can be set with 5 mV resolution.
