Use the Mod button to generate modulated waveform. DG3000 Series can generate
AM, FM, FSK, PM and PWM modulated waveforms. Modulating parameters vary by
the types of the modulation. 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), Frequency Range, Internal 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 cover how to set these parameters in details by the types of the Modulation.
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 in
Table 2-16.

The Amplitude Range (also called ‘Percentage Modulation’). Modulation Depth
varies from 1% to 120%.
In the 0% Modulation, the output amplitude is the half of the set one.
In the 100% Modulation,the output amplitude is the same with the set one.
When the modulation is greater than 100%, the instrument output no greater
than 10 Vpp. 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.
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

For an External Source, the Deviation is controlled by the ±5V voltage Level of
the Connector connected to the [Modulation In]. +5V corresponds to the
selected Deviation and -5V to the negative selected Deviation.
The FSK Modulation is a modulation method, the output frequency of which switches
between two the pre-set frequencies (Carrier Waveform Frequency and the Hop
Frequency). The Frequency for the Output Frequency to switch from the carrier
waveform frequency to and from the Hop frequency is called the FSK rate. The
frequency by which the output frequency switch from each other is determined by the
Internal Frequency generator or the Signal Voltage Level offered by the Trig In
connector in the rear panel:

Notes:The frequency shown on DG3000 may vary greatly from what you imagine.
This is because that DG3000 consider the 512K points acquired as a period. If you
want to get the real period of the generated waveform, you have to use the frequency
value shown on DG3000 times the number of the real period in this false period.
As shown in the figure below, this is the waveform shown on another DS1000 using
the above operation. Please note that the frequency shown on this instrument is the
same as the precious one.

Activate the Sync Signal on the [Sync]
Connector on the front panel.
Deactivate the Sync Signal on the [Sync]
Connector on the front panel.
The Generator provides Sync output through the [Sync] Connector on the Front Panel.
All standard output functions (except DC and Noise) have a corresponding Sync
Signal. For some Sync applications, they can be disabled if users do not want to use
them,
• In the default setting, the Sync Signal should be connected to the [Sync]
Connector (activated). When the Sync Signal is disabled, the output Voltage of
the [Sync] Connector is Level Low.
• In the Inverse Mode, the Waveform that corresponds to the Sync Signal does not
Inverse.
• The Setting of Mark Signal in the Sweep Mode will deactivate the Sync Signal.
Thus, when the Mark Frequency is enabled (Sweep Mode activated), the Sync
Signal Setting will be overlooked.
• For Sine, Square and Pulse Signal, the Sync Signal is a Square Signal with 50%
Duty Cycle. When the output is positive, The Sync Signal is TTL Level High
compared to 0 V Voltage or DC Offset; when the output is negative, The Sync
Signal is TTL Level Low compared to 0 V Voltage or DC Offset.
• For Square Waves, the Sync Signal is a Square Wave with the same Duty Cycle
with the main output Square Wave. When the Output is positive, The Sync Signal
is TTL Level High compared to 0 V Voltage or DC Offset; when the output is
negative, The Sync Signal is TTL Level Low compared to 0 V Voltage or DC
Offset.
• For 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 Level High.
• For Internal Modulating AM, FM and PM, 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
Level High. 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
• For 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 Level High.
• For a Sweep which disables the Mark function, the Sync Signal is a Square
Waveform with 50% Duty Cycle. When the Sweep starts, the Sync Signal is TTL
Level High and turns Low at the Center of the Sweep. The Sync Frequency equals
the specific Sweep time. For a Sweep that enables the Mark Function, the Sync
Signal is TTL Level High at the beginning of the Sweep and turns Low at the Mark
Frequency.
• For the Burst, when the burst starts, the Sync Signal is Level High. At the specific
point when the Cycle Number ends, the Sync Signal turns Level Low (If the
Waveform has a relative starting phase, then intersections may occur). For an
infinite burst, the Sync Signal is the same with the Sync Signal of the continuous
Signal.
• For 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 end of the last
period (If the Waveform has a relative starting phase, then intersections may
occur).
For the [Output] Connector on the Front panel, the Generator has a built-in 50Ω
series impendence. If the actual load does not match the set one, the displayed
amplitude and offset are incorrect. This function is used to match the displayed
voltage with the expected one.
Steps for setting the Load:
(1). Press Utility Æ Output Setup Æ Load, to enter the following interface.
Please note that the Load Parameter shown on the right bottom is the default
setting when the power is on or the pre-set load value. If the current value is
valid for the output, then is current value will be used.
(2). Input the desired Load Value.
Use the Keypad or the Knob to enter the desired value and choose the unit, Ω or
KΩ, press the corresponding button.

Instruction
DG3000Series has a fixed 50Ω Series Impendence. No matter what Value the set
parameter is, if the real load is different from the set one, the displayed voltage
will not equal the real voltage.
Press Utility Æ Output Setup Æ Invert, to set the Inverse Waveform Output.
When the waveform is Inverse, no offset will change. An inverse waveform will be
displayed in the Graph Mode.
