Use the Mod button to generate modulated waveform. DG2000 Series can generate
AM, FM, FSK, PM or PWM modulated waveforms. The modulation parameters should
be set in different types of modulation. For example, in AM, users can set the Source
(Internal/ External), depth, Modulating Frequency, Modulating Waveform and Carrier
Waveform; in FM, users can set the Source (Internal/ External), Frequency Deviation,
Modulating Waveform and Carrier Waveform; in FSK, users can set the Source
(Internal/ External), Hop Frequency, FSK Rate, Modulating Waveform and Carrier
Waveform; while in PM, users can set the Source (Internal/ External), Phase Deviation,
Modulating Frequency, Modulating Waveform and Carrier Waveform, etc.
We will explain how to set these parameters in details according to different types of
Modulation.
Figure 2-39 The setting Interface of Modulated Waveform
The modulated waveform consists of two parts: the Carrier Waveform and the
Modulating Waveform. In AM, the Amplitude of the Carrier Waveform varies with the
instantaneous voltage of the modulating waveform. The Parameters for the AM are
shown in table 2-16.

Modulation Depth
The Amplitude Range (also called “Percentage Modulation”). Modulation Depth
varies from 0% to 120%.
z In the 0% Modulation, the output amplitude is the half of the set one.
z In the 100% Modulation, the output amplitude is the same with the set one.
z For an external source, the depth of AM is controlled by the voltage level of the
connector connected to the [Modulation In]. +5V corresponds to the currently
set depth 100%.
The modulated waveform consists of two parts: the Carrier Waveform and the
Modulating Waveform. In FM, the Frequency of the Carrier Waveform varies with the
instantaneous voltage of the modulating waveform. The Parameters for the FM are
shown in figure 2-43.
Figure 2-43 The Setting Interface of FM Waveform
Press Mod Æ Type Æ FM , enter the following interface.
z The Deviation should be equal to or less than the Carrier Waveform Frequency.
z The Sum of the Deviation and the Carrier Frequency should be equal to or less
than maximum frequency of the selected function plus 100 kHz.
zFor an External Source, the Deviation is controlled by the ±5V voltage Level of
the Connector connected to the [Modulation In]. +5V adds to the selected
Deviation, lower external voltage generates less deviation, while negative
voltage reduces the modulated signal frequency below the corresponding
carrier’s.
The FSK Modulation is a modulation method, the output frequency shifts between the
two pre-set frequencies (Carrier Waveform Frequency and the Hop Frequency). The
Frequency for the Output Frequency to shift from the carrier waveform frequency to
and from the Hop frequency is called the FSK rate. The frequency by which the output
frequency shift from each other is determined by the Internal Frequency generator or
the Signal Voltage Level offered by the [Ext Trig/FSk/Burst] connector in the rear
panel:
z If you choose the Internal Modulation, the frequency at which the output
frequency shifts between the carrier frequency and the Hop frequency is
determined by the set FSK rate.
z If you choose External Modulation and overlook the FSK rate, the output frequency
is determined by the Voltage Level of the [Ext Trig/FSk/Burst] connector on the
rear panel. If the Voltage Level is low, then generate the carrier frequency; when
the voltage level is High, generate the Hop frequency.
Figure 2-46 The Setting Interface of FSK Waveform
Press Mod Æ Type Æ FSK , enter the following interface.
The modulated waveform consists of two parts: the Carrier Waveform and the
Modulating Waveform. In PM, the Phase of the Carrier Waveform varies with the
instantaneous voltage Level of the modulating waveform. The Parameters for the PM
are as shown in figure 2-49.
Figure 2-49 The Setting Interface of PM Waveform
Press Mod Æ Type Æ PM , enter the following interface.
The modulated wave is composed of the carried wave and the modulation wave. In the
PWM ( Pulse-Width Modulation), the pulse width of the carried wave varies with the
instantaneous voltage Level of the modulating waveform. The Parameters for the PWM
are shown in figure 2-52.
Figure 2-52 The Setting Interface of the PWM Waveform
The PWM function is only for modulating the Pulse wave. Once in the other wave
interface, press Mod you may discover the softkey PWM can not be used while
choosing the modulation type, it can enter the PWM interface only by pressing Mod
Once in the Pulse interface.
Press Pulse and enter the PWM interface, then press Mod, enter the following menu.
In the frequency sweep mode, the function generator “sweep” from the start
frequency to the stop frequency at the sweep rate you specify. Sweeping can be
generated by Sine, Square, Ramp or Arbitrary Waveforms (Pulse, Noise and DC are not
allowed).

Press Sweep button, in the Normal Mode, the operation menu will appear on the
bottom of the screen, see figure 2-56. Set the Waveform parameters by using the
operation menu.
Burst Function can generate versatile waveforms in burst, which can last specific times
of waveform cycle(N-Cycle Burst), or when the external gated signals( Gated Burst) is
applied, any waveform could be used. But noise can only be used in Gated Burst.
Press Burst button, in the Normal Mode, the operation menu will appear on the bottom
of the screen, see figure 2-58. Set the Waveform parameters by using the operation
menu.
Figure 2-58 The Setting Interface of Burst Waveform
N-Cycle has specific number of waveform cycles, and every burst is activated by a
trigger event. Gated burst controls burst by external source.
Cycle Number
Set the number of Waveform Cycle in an N-Cycle (1 to 1,000,000 or Infinite).
If you choose Infinite, then a continuous waveform will be generate which will not stop
until a trigger event happens (Trigger button is pressed).
z If needed, Burst Period will increase to cater to the specific number of cycles.
z For a frequency greater than 25MHz, only a bust with infinite cycles is allowed.
z For an infinite-cycle Burst, External or Manual Trigger is needed to activate burst.
Phase
Define the Start and the Stop Point in a waveform. The phase varies from -360° to
+360°, and the default setting is 0°. For an Arbitrary Waveform, 0° is the phase of the
first waveform point.
Period
Set the time span between an N-Cycle Burst and the next. If necessary the period will
increase to reach the specific number of cycles in a burst.
Burst Period> Period X Burst Number
Delay
Set the Time Delay between the Trigger Input and the Start of the N-Cycle Burst. The
minimum delay is a function of the specific burst period, and should always be greater
than 0.

Notes:The frequency shown in DG2000 may be different greatly from that you
imagine. This is because that DG2000 considers the acquired 512K points as a period.
If you want to get the real period of the generated waveform, you have to multiple the
frequency value shown on DG2000 with the number of the real period in this false
period.

Sync Switch Setting:
When the amplitude is low relatively, you can reduce the distortion of the output
signal by prohibiting the Sync Signal. And the current storage is in the Non-Volatile
Memory.
The Generator provides Sync output through the [Sync] Connector on the Front Panel.
All the standard output functions (except DC and Noise) have a corresponding Sync
Signal. For some Sync applications, they can be prohibited if users do not want to use
them.
zIn the default setting, the Sync Signal should be connected to the [Sync]
Connector (activated). When the Sync Signal is prohibited, the output voltage
Level of the [Sync] Connector is Low.
z In the Inverse Mode, the Sync Signal does not Inverse.
z For Sine, Square, Ramp and Pulse Signal, the Sync Signal is a Square Signal with
50% Duty Cycle. When the output is positive, the Sync Signal is TTL High Level
compared to 0 V Voltage or DC Offset; when the output is negative, The Sync
Signal is TTL Low Level compared to 0 V Voltage or DC Offset.
zFor Arbitrary Waveform, the Sync Signal is a Square Waveform with 50% Duty
Cycle. At the time when the first output waveform point is generated, the Sync
Signal Voltage is TTL High Level.
zFor AM, FM and PM in Internal Modulation, the Sync Signal reference is the
Modulated Signal (not the Carrier Signal). The Sync Signal is a Square Waveform
with 50% Duty Cycle. In the first half modulation period, the Sync Signal is TTL
High Level. For External Modulation, the Sync Signal reference is the Carrier Signal
(not the Modulated Signal). The Sync Signal is also a Square Waveform with 50%
Duty Cycle.
zFor FSK, the Sync Signal Reference is the Hop Frequency, and the Sync Signal is a
Square Waveform with 50% Duty Cycle. For the Hop Frequency, at the hopping
point, the Sync Signal is TTL High Level.
zFor the Burst, when the burst starts, the Sync Signal is High Level. At the specific
point when the Cycle Number ends, the Sync Signal turns Low Level (If the
Waveform has a relative starting phase, it may be not zero intersections). For an
infinite burst, the Sync Signal is the same as the Sync Signal of the continuous
Signal.
zFor the External Gated Burst, the Sync Signal follows the External Gated Signal.
But, please note that this signal will not turn Level Low until the last period end (If
the Waveform has a relative starting phase, it may be not zero intersections).
For the [Output] Connector on the Front panel, the Generator has a built-in 50Ω
series output impedance. If the actual load does not match the set one, the
amplitude and offset displayed are incorrect. This function is used to match the
displayed voltage with the expected one.
Steps for setting the Load value:
(1) Press Utility Æ Output Æ Load , enter the following interface.
Please note that the Load Parameter shown on the right bottom is the default
when the power is on or the pre-set load value. If the current value is valid for
