4.2.2 Start Frequency and Stop Frequency Setting
Start frequency and stop frequency are the upper limit and lower limit of frequency scanning. Press Return softkey
to back to sweep interface. Press Parameter
→ Start Frequency→StopFrequency softkeys in turn, then enter
number with number keyboard and press corresponding unit softkey.
If start frequency is lower than stop frequency, DDS function generator sweeps from low frequency to high
frequency.
If start frequency is higher than stop frequency, DDS function generator sweeps from high frequency to low
frequency.
If start frequency is equivalent to stop frequency, DDS function generator sweeps output fixed frequency.
Synchronous signal of sweep mode is a signal that is low from the start of sweep time to the middle of
sweep time, and is high from the middle of sweep time to the end of sweep time.
The default of start frequency is 1kHz, and stop frequency is 2kHz. Different sweep waveform has different settable
range of enabling and stop frequency, settable frequency range of each sweep wave are shown in the following
