When External selected, generator takes external source, the detail description refer to
chapter 3.14.
5.12 Frequency List Sweep
Press 【Sweep】 key to enter into sweep mode. the working mode displays as sweep,
the sweep sketch and menu will be both displayed.
5.12.1 Set Sweep Signal
First set the shape, amplitude and offset for sweep signal. The waveform generator can
produce a frequency list sweep for most waveforms mentioned above, but some
waveforms are not available.
In frequency sweep mode, the change of frequency only by linearly and logarithm, and
each point stand period during sweeping never change. So in some occasion, a
frequency list with arbitrary regularity or without any regularity need to be output, and
dwell time on each frequency point can be set, then list sweep will be used. In the
frequency list mode, the function generator “steps” through the frequencies contained in
a list, dwelling on each frequency for a specified period.
5.12.2 Sweep Mode
Press〖Sweep Mode〗and select List to display the list sweep menu.
5.12.3 Frequency List
Generator has default frequency list, which ranges from 1kHz to 128kHz. User can
create its own frequency list, the maximum length of which is 128 frequency value.
(1) Press 〖List Number〗softkey and set the desired list number.
(2) Press 〖List Freq〗will be automatically selected and set the frequency value
according to selected list number.
(3) Press 〖Next〗softkey can add 1 on list number and set the following frequency value.
Using this method to create or modify a frequency list.
(4) When complete the new list, you can save the current list by state storage method,
the the data of which won’t be lost even power-off and also could be recalled in
need. The detail method is referred to chapter 5.20.
5.12.4 Start Number and Stop Number
In the frequency list sweep mode, the waveform generator moves from the start number,
output each frequency value contained in a list one by one, until to the stop number.
