channels. Pressing down this softkey will re-configure the two channels, and
enable the generator to output with specified frequency and start phase.

For two signals whose frequencies are the same or in multiple, this operation will
align their phases. For example, assume a sine waveform (1kHz, 5Vpp, 0 °) is
output from CH1, while an other (1kHz, 5Vpp, 180°) f rom CH2. Us e an os cillos cope
to sample and display the two signals, and then toggle the channel output switch
of the generator, you will see that t he wa veforms sho wn on the oscilloscope do not
always have a phase deviation of 180°. At this point, press Align Phase on the
generator and the waveforms shown on the oscilloscope will have a phase
deviation of 180° without any adjustment of the start phase of the generator.

To Create New Arbitrary Waveform

Press Arb, use to open the 2/2 menu page, and then press Create New to
open the arbitrary waveform crea t ion interface.

1. Cycle Period

Press this softkey and us e the numeric k eyboard or direction keys and knob to
set the cycle period of the new waveform. Cycle period is the bou ndary time of
the waveform and the range is from 25.0ns to 1Ms.
Note that the time of the last point that can be defined should be lower than
the cycle period.

2. High VLimit

Press this softkey and us e the numeric k eyboard or direction keys and knob to
set the level upper limit of the new waveform. The level upper limit is the
maximum voltage that can be set during waveform edit. The level upper limit
must be greater than the “Low VLimit” currently set and lower than or equal
to +5V (50Ω).

3. Low VLimit

Press this softkey and us e the numeric k eyboard or direction keys and knob to
set the level lower limit of the new waveform. The level lower limit is the
minimum voltage that can be se t during waveform edit. The level lower limit
must be greater than or equal to -5V (50Ω) and lower than the “High VLimit”
currently set.

4. Init #Points

When creating a new waveform, the wavefor m editor will automatically create
a waveform with two points. By default, point 1 is located at 0 seconds and
point 2 at half of the specified cycle period. In addition, the levels of the two
points are equal to the s pecified “Low VLimit”. Press this softkey and use the
numeric keyboa rd or direction keys and knob to set the initial points of the new
waveform. DG4000 allows users to create arbitrary waveform with 1 to 16384
(16K) points. If in need, you can “Insert Point” or “Delete Point” later.
