Modulation phase
The modulating signal of internal modulation is a 50%
duty cycle square wave. Set modulation phase range
External

Modulation phase
When the external modulation is selected, the
modulation signal is input by the [Ext Trig] on the rear
panel. Only Modulation phase parameters need to be
set.
2.3 Frequency Sweep Waveform Setup
In frequency sweep mode, the ET3340 outputs variously from the start frequency to the stop
frequency in specified time. Sweep waveform can be produced with sine, square, ramp, pulse,
or arbitrary waveforms (noise and DC are not allowed to be scanned).
Press
, and the system will display the operation menu as shown in Figure 2-27. Set the
output waveform parameters of the sweep wave by operating the sweep menu.
