To Set Frequency
Frequency is one of the most important parameters of basic waveforms. For
different instrument models and different waveforms, the setting ranges of
frequency are different. For detailed information, please refer to “Frequency
Characteristics” in Specifications. The default frequency is 1kHz.
The frequency displayed on the screen is the default value or the frequency
previously set. When the instrument function is changed, if this frequency is valid
under the new function, the instrument will still use this frequency; otherwise, the
instrument would display prompt message and set the frequency to the frequency
upper limit of the new function automatically.
Press Freq/Period to highlight “Freq”. At this point, use the numeric keyboard or
direction keys and knob to input the frequency value. Then, select the desired unit
from the pop-up menu.
 For the input method of frequency value, refer to the introduction in
Parameter Setting Method.
 The frequency units available are MHz, kHz, Hz, mHz and μHz.
 Press this softkey again to switch to period setting. At this point, “Period” is
highlighted.
 The period units available are sec, msec, μsec and nsec.
