7.1.6 Frequency Measurement (FREQ)
Measurement method
Reciprocal
A frequency over the above range is displayed but not guaranteed.
Input signal voltage range 100 mVrms to 700 Vrms and 10% of each voltage range or more (sinu-
soidal wave)
(However, the input signal is restricted to the maximum allowable
applied voltage.)
