dBm is the unit for signal power absolute value. The relationship between dBm and Vrms
fulfills the following equation:
dBm =10 lg (
W is the unit of the signal power. R represents the channel output impedance value which
must be a certain value. Therefore, dBm is not available when the output impedance is set
to "HighZ".
Offset/Low Level
Click or tap the Offset/LowL button to set the parameter to "Offset". "Offset" is now
highlighted. Click or tap its input field and use the pop-up numeric keypad to set the
offset for sine wave. The range of offset is limited by the "Impedance" and
"Amplitude/High Level" setting. The default value is 0 Vdc.
Click or tap the button again to toggle the parameter to "LowL". Low Level = Offset -
Amplitude/2. The low level range is related to the high level setting value. That is,
high level minus low level cannot exceed the current range of amplitude (
Range of Amplitude
TIP
The "Ampl" and "Offset" buttons appear at the same time, so are "HighL" and "LowL" buttons.
For example, selecting "Offset" automatically toggles the "Ampl/HighL" parameter to "Ampl".
Starting Phase
Click or tap the Phase input field to set the starting phase, which ranges from -360°
to 360°. The default phase is 0°, and the resolution is 0.01°.
Channel Setup
You can also click or tap the "Channel" tab in the
channel setup interface to configure channel output. For details, please refer to
Channel Setup
Enable the Channel Output
After setting the waveform parameters, you need to enable the channel to output
waveforms. You can enable the channel output in the following ways.
• Click or tap the channel label at the bottom of the screen.
• Press the front-panel
• Click or tap the channel identifier at the left side of the parameter configuration
area.
