to select the source. If the source is External, use the
Ext Trig/Burst/Fsk
In
connector in the rear panel to input the external signal, then skip ahead to step (5).
If you choose Internal, continue to the steps below.

to set Hop Frequency. The range is 2 mHz - 25kHz.
Term Explanation
FSK Rate:
The frequency at which the output frequency shifts between the carrier frequency
and the Hop frequency (Internal Modulation only).
PWM (Pulse Width Modulation)
(only in AG2052F and AG2062F)
The modulated waveform consists of two parts: the Carrier Waveform and the
Modulating Waveform. PWM can only be used for pulse modulation, so the Carrier
Waveform must be Pulse. In PWM, the width of the Carrier Waveform (Pulse) varies with
the instantaneous voltage of the modulating waveform.
How to set the parameters of PWM
(1)
Press
Mod
function button, then press
F1
to select Mod.
(2)
Press
F1
to switch Mod Type to PWM. If the Carrier Waveform is not Pulse, the
system will switch it to Pulse automatically.
(3)
Press
button to display the waveform and parameters of the Carrier
Waveform. You can change the parameters, please refer to
on page 16. Press
button again to return to the Modulation mode interface.
(4)
Press
F5
to select the source. If the source is External, use the
Ext Mod In
connector in the rear panel to input the external signal, then skip ahead to step (6). If
you choose Internal, continue to the steps below.
(5)
Press
F2
to choose Mod Shape, you can choose Sine, Square ,Ramp or Arb .
(6)
Press
F3
to set Mod Frequency. The range is 2 mHz - 20 kHz (Internal source
only).
(7)
Press
F4
to set Width Deviation/Duty Deviation (depends on the P_Width/Duty
menu item of the Pulse setting menu when you exit the Modulation mode). The
maximum range of the Duty Deviation is the smaller one in [Pulse Duty, 1-Pulse Duty].
The maximum range of the Width Deviation is Pulse Width.
To Generate Sweep
Sweep function is only used for CH1. In the frequency sweep mode, the generator "steps"
