Attention!
To measure the frequency and duty ratio, the signal must reach certain amplitude: the voltage signal
amplitude shall be
500mVp-p; the current signal shall be
20mA RMS. For signals which are
close to 10MHz or higher, a large amplitude of (voltage/current) signal may be required.
Attention!
When carrying out frequency counting and measurement of duty ratio, manual mode shall not be
adopted and the function of relative value (REL) and Peak value holding shall not be used either.
Instruction! For higher frequency, the automatic measurement function under scopemeter mode may be utilized.
