Setting the Pulse Width

RIGOL

Key Points:

 Pulse width is limited by the minimum pulse width and the Pulse

period.

Minimum Pulse width= 20ns Pulse width ≥ Minimum Pulse width Pulse width ≤ Pulse period－Minimum Pulse width

 Pulse duty cycle is limited by the minimum pulse width and the Pulse

period.

Pulse duty cycle ≥ 100 × Minimum Pulse width ÷ Pulse period Pulse duty cycle ≤ 100 × (1－Minimum Pulse width ÷ Pulse period)

 Settings of “Pulse Width” and “Duty Cycle” are equivalent.

Once a parameter is changed, the other one will change accordingly. For instance, the current period is 1ms, the pulse width is 500µs and the duty cycle is 50％, when setting the pulse width to be 200µs, the duty cycle will become 20％.

The Amplitude Range (also called “percentage Modulation”). Modulation Depth varies from 0% 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.

Frequency Deviation

 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 1kHz.

 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. Lower external voltage generates less deviation, while negative voltage reduces the modulated signal frequency to below the corresponding carrier’s.

To Set FSK Waveform

The FSK Modulation is a modulation method, the output frequency of which switches between the two pre-set frequencies (Carrier Waveform Frequency and the Hop Frequency). The Output Frequency which shifts from the carrier frequency to 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 [Ext Trig/FSK/Burst] connector on the rear panel.

 If you choose the Internal Modulation, the frequency at which the output

frequency shift between the carrier frequency and the Hop frequency is determined by the set FSK rate.

 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.

Carrier Waveform used in FSK can be set through the Sine、Square、Ramp、Arb button on the front panel.

To Set the Sync Output

The Generator provides Sync signal output of CH1 through the [Sync Out] Connector

on the Rear 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.

 In the default setting, the Sync Signal output is disabled. The output Voltage of

the [Sync Out] Connector Level is Low.

 In the Inverse Mode, the Waveform that corresponds to the Sync Signal does not

Inverse.

 If frequency of the standard output function (except DC and Noise) is higher than

2MHz, the Sync output will automatically put off.

 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 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 the internal Modulating of 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 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

User’s Guide for DG10× 2 Series

RIGOL

Waveform has a relative starting phase, then intersections may occur). For an infinite burst, the Sync Signal is the same as 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 last period end (If the Waveform has a relative starting phase, it may be not intersections).

1. To Set the Output Load

For the [Output] Connector on the Front panel, the Generator has a 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  CH1  Load, enter the following interface.

Figure 2-56

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 the current value can be used.

Key Points:

1. Channel Coupling

(1) The coupling is only used for frequency and phase, as shown in the following

figure, the base channel will mark with a “*” sign on the screen. It indicates that CH1 has coupling in the phase parameter.

Coupling Sign Instruction

User’s Guide for DG10× 2 Series

Figure 2-61

(2) Only frequency or phase can be coupled each time, it depends on the current

selection is FreDev or PhaDev.

2. Channel Copy

(1) Only when the coupling is closed, the Copy menu would appear. (2) Only parameters will be copied in the channel copy operation. (3) Channel copy is limited by parameters inspection.

 Frequency limitation

Different waveforms have different upper/lower limits of the frequency. When waveforms in the two channels are different, the highest frequency can be copied depends on the waveform which has lower frequency. For instance, a Sine waveform of 5MHz can not be copy to a Ramp (frequency upper limit is 150 KHz).

 limitation of the Amplitude and Output impedance setting

The upper/lower limits of Amplitude are different in different channels and modes. Before copying, the Output impedance setting of the two channels should be the same. Take CH1 for example, to set the Output impedance, press Utility CH1  Load/High Z, then set the value in need.

 Channel inverting limitation

If a channel has been set to Invert, after the copying, the two channels will still have 180° phase deviation though the “Phase” parameter has been copied.

Figure 2-64

To set the sensitivity

Suggestion:

 For low amplitude signal, the “medium” or “high” sensitivity should be used.  For low frequency signal with high amplitude and slower rising edge, low

sensitivity is a better choice.

3. To Set the Trig Level

The trig level (-3V～+3V) is divided into 1000 (00.0~99.9) shares, each “0.1” is 6 mV, it means the adjustment interval is 6 mV. For example, the input is “62.0”,

then the trig level is: -3V + (62.0 / 0.1) × 6 mV=0.72V.

(1) Press Utility  Count  Setup  TrigLev to set the trig level.

The trig level display on the screen is the default value when power on or the value set at the last time. If the current value is effective, it could be use immediately.

(2) Input the required trig level.

Use the knob to change the value as shown in the following figure, the counter will immediately adjust the trig level, and trigger according to the specified value.

To set the high frequency on/off

Suggestion:

 To measure low frequency signal lower than 1kHz, you should put on the high

frequency restrain to filter the high frequency noise disturb.
