Term Explanation: Pulse Width: The time span between thresholds of 50% of the rising edge

amplitude to the next 50% of the falling edge amplitude.

Edge Time:

The time span between the thresholds of the 10% to 90% of the rising edge amplitude is called Rising Time. The time span between the thresholds of the 90% to 10% of the falling edge amplitude is called Falling Time. The Rising Time and the Falling Time together called Edge Time.

To Generate the Modulated Waveform

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 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 Deviation should be equal to or less than the Carrier Waveform Frequency.  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.

 For an External Source, the Deviation is controlled by the ±5V voltage Level of

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:

The Seamless Interaction of DG3000 and DS1000

Above we have introduced to you the interfaces of DG3000, and mentioned the USB Host Interface. Below, we will introduce to you how to use this interface to connect DG3000 and DS1000 to realize the nondestructive data Transmission. Step one, Connect DG3000 with DS1000, and acquire data. Step two, Connect the USB Host Interface of DG3000 with the USB Device Interface of DS1000. View the waveform acquired. The procedures are as follows:

Press Recall and DG3000 will recall the waveform data acquired by DS1000 into the Volatile Memory.

Note: when recalling, DG3000 will recall once and write once, so there will be 2 processing bar. If there is only one shown, it means that the recall operation is unsuccessful.

To generate the waveform acquired

Press Arb Æ Sel Wform Æ Volatile Wform, to load the waveform just recalled.

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.

To Set the Utility Function

With the Utility Function, you can set the parameters of the Generator such as: DC On/Off, Sync On/Off, Output Parameter, Interface Parameter, System Setting and Testing Parameter. The DC switch offers the options of DC output or Arbitrary Waveform Output. Sync Switch offers the option to choose the Sync Signal or not. Output Setting provides the parameter setting for Load/Impedance, Range, Normal/ Inverse and Phase. Interface Setting offers the storage and load of the configure parameter setting for GPIB (IEEE-488), LAN, RS232 or USB remove Control. The System Setting provides the setting for Language, Display, Beep, Screen Guard, Format, Power System Configure and default setting; Test provides the self-testing and calibration storage.

To Set the Sync Output

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

User Guide for DG3000 Series

RIGOL

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).

1. To Set the Output Load

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.
