display prompt message and set the frequency to the frequency upper limit of the new
function automatically.
Press [Setting] > Frequency softkey. At this point, use the numeric keypad to input the
value of the frequency and select the desired unit from the pop-up unit menu, or use the
direction keys and knob to modify the current value.
1. For the input method of frequency value, please refer to the introduction of
"
Parameter Setting Method
".
2. The frequency units available are MHz, KHz, Hz and mHz.
3. Press [Utility] > Units softkey and press Frequency/Period softkey to switch
Frequency in the parameter to Period. Press [Setting] > Period softkey to modify
the period parameter.
4.
The period units available are sec, msec, μsec and nsec.
5.2.3 Set the Amplitude
The amplitude range is limited by Frequency or Period and Impedance settings. Please
refer to "Output Characteristics" in Specifications. The default value is 200mVpp.
The amplitude displayed on the screen is the default value or the amplitude previously
set. When the instrument configuration (e.g. frequency) is changed, if this amplitude is
valid, the instrument will still use this amplitude; otherwise, the instrument would display
a prompt message and set the amplitude to the amplitude upper limit of the new
configuration automatically.
Press [Setting] > Amplitude softkey. At this point, use the numeric keypad to input the
value of the amplitude and select the desired unit from the pop-up unit menu, or use the
direction keys and knob to modify the current value.
1. For the input method of amplitude value, refer to the introduction in "
Parameter
Setting Method ".
2.
The amplitude units available are Vpp, mVpp, and Vrms, dBm (50Ω impedance).
3. Press [Utility] > Units softkey and press Amplitude / High Level softkey to switch
the Amplitude and Offset in the parameter to High Level and Low level . Press
[Setting] > High Level or Low Level softkey to modify high level or low level
parameters.
4. The high level units available are V and mV.
Tips:
Switch between Vpp and Vrms
Vpp is the unit for the signal peak-peak value and Vrms is the unit for the signal effective
value. The default unit of the instrument is Vpp. Users can quickly switch the current
amplitude unit from the front panel.
For different waveforms, the relations between Vpp and Vrms are different. Take sine
waveform as an example; the relation of the two units is as shown in the figure below.
