Note 1: The instrument needs to operate continuously at 0 °C ~ +40 °C for more than
30 minutes. The above specifications are at 25°C. All specifications shown
are guaranteed except for those marked "typical".
UT-M14 operating temperature is 0 °C ~ +40 °C, it is recommended to
reduce the output power and the operating frequency of the UT-M14 when
the ambient temperature is above 40 °C.
Note 2: Full power bandwidth refers to the maximum frequency of the amplifier
outputs the maximum amplitude of distortion-free AC signal:
SR (Slew Rate): When input a large step signal into the power amplifier, the
Vomax: The power amplifier can output the maximum amplitude of
distortion-free AC signal.

Full power bandwidth
output slope of the signal is found to saturate into a fixed
constant at a certain point, which is called the Slew Rate of
the power amplifier.
