The limits given are for the ambient temperature range of 0_C to +30_C. Reduce the upper bandwidth frequencies by
5 MHz for the TDS 600B or by 2.5 MHz for the TDS 500D/700D for each _C above +30_C.

The numbers given are valid 0_C to +30_C and will increase as the temperature increases due to the degradation in
bandwidth. Rise time is calculated from the bandwidth. It is defined by the following formula:
Note that if you measure rise time, you must take into account the rise time of the test equipment (signal source, etc.) that
you use to provide the test signal. That is, the measured rise time (RT
m
) is determined by the instrument rise time (RT
i
) and
the rise time of the test signal source (RTgen) according to the following formula:

The values given are the maximum absolute difference between the value at the end of a specified time interval after the
midlevel crossing of the step and the value one second after the midlevel crossing of the step, expressed as a percentage
of the step amplitude.
