User Manual

b)Set Starting and Stop Frequency

Starting frequency and stop frequency are upper limit and lower limit of frequency sweep.

Function/ arbitrary waveform generator always sweeps from starting frequency to stop

frequency and then returns to starting frequency. To set starting or stop frequency, please

press Param → StartFreq or StopFreq , input number through numeric keyboard and press

corresponding soft key of unit to finish setting.

Figure 4- 33 Set frequency sweep parameters

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:
