Frequency Sweep Mode - UNI-T UTG2122B User Manual

● When starting frequency < stop frequency, function / arbitrary waveform generator sweeps
from low frequency to high frequency.
● When starting frequency> stop frequency, function / arbitrary waveform generator sweeps from
high frequency to low frequency.
● When starting frequency= stop frequency, function / arbitrary waveform generator outputs
fixed frequency.
● The synchronous signal of frequency sweep mode is low from starting point to midpoint of
frequency sweep time, and high from midpoint to end of frequency sweep time.
By default, starting frequency is 1kHz and stop frequency is 2kHz, but the range of starting and stop
frequency can vary with frequency sweep waveform. See the table below for the frequency range
of frequency sweep wave:

3.2.3 Frequency Sweep Mode

For linear frequency sweep, waveform generator changes output frequency in a linear way during
frequency sweep; for logarithmic frequency sweep, waveform generator changes output frequency
in a logarithmic way. Linear frequency sweep mode is default.To change
it, please press soft key Type → Log on the interface for starting frequency sweep mode (please
press Return first to enter the interface for selecting frequency sweep waveform).
