4. To set the amplitude
Press Amplitude to set the amplitude of the current signal. For the setting
methods, refer to “
Parameter Setting Methods”. When the impedance is set
to HighZ, the range available is from (-2.5 V+current amplitude/2) to (2.5
V-current amplitude/2) and when the impedance is set to 50 Ω, the range
available is (-1.25 V+current amplitude/2) to (1.25 V-current amplitude/2).
5. To set the DC offset voltage
Press Offset to set the DC offset of the current signal. For the setting methods,
refer to “
Parameter Setting Methods”. When the impedance is set to HighZ,
the range available is from (-2.5 V+current amplitude/2) to (2.5 V-current
amplitude/2) and when the impedance is set to 50 Ω, the range available is
(-1.25 V+current amplitude/2) to (1.25 V-current amplitude/2).
Note: The offset value can only maintain three effective digits. For example,
when the amplitude is set to 10 mVpp (the impedance is 50 Ω), the offset range
calculated is -1.245 V to 1.245 V, but the actual offset range is -1.24 V to 1.24 V.
6. To set the start phase
Press Start Phase to set the start phase of the current signal. For the setting
methods, refer to “
Parameter Setting Methods”. The range available is from
0° to 360°.
7. Align phase
Press AlignPhase to re-configre the two channels and enable the signal source
to output with specified frequency and phase. For two signals whose frequencies
are the same or in multiple, this operation will align their phases. Use the
oscilloscope to sample and display the waveforms of the two channels and you
will see that the phases of the two waveforms shown on the oscilloscope
changed. At this point, press AlignPhase and the waveforms on the oscilloscope
will restore the current phase deviation of the two channels.
8. Modulation
Press Modulation to turn the modulation function on or off. For detailed
information about modulation function, please refer to “
Modulation”.
