3)Set waveform frequency
In N cycle and gating modes, waveform frequency defines signal frequency during period
of pulse train. In N cycle mode, the pulse train will be output with designated cycle index
and waveform frequency. In gating mode, when trigger signal is at high level, pulse train is
output with waveform frequency.
Note: waveform frequency is different with period of pulse train that designates interval
between pulse trains (only for N cycle mode). The default frequency of waveform is 1kHz.
See the table below for the range:

To set waveform frequency, please use multi-functional knob and direction key or press
soft function key Freq , input the required value and select the unit after selecting waveform.
b)Type of Burst
UTG2000B can output three types of pulse train, N cycle, gating and infinite. The default
type is N cycle.
N cycle mode
Press soft keys Type → N Cyc successively on the interface for starting pulse function to
enter N cycle mode. In this mode, the waveform generator will output a waveform with
designated recurring number (pulse train) upon receiving trigger. After outputting a designated
number of cycles, the waveform generator will stop and wait for the next trigger. The trigger
source of pulse train can be internal, external or manual in this mode. To change it, you
can use multi-functional knob and direction key on the interface for selecting type of pulse
train (as shown in the figure below) or press soft function key Param → Source
Note: if the trigger source is external, trigger output options will be hidden. Because external
digital modulation interface(FSK Trig connector) cannot be used as external tri gger input
and internal trigger output at the same time.
