To Set Parameters for Pulse

To output a pulse, users need to set the “Pulse Width/Duty Cycle”, “Leading edge”, “Trailing edge”, “Delay” and “Recover Delay” in addition to the basic parameters

(such as frequency, amplitude, DC offset voltage, start phase, high level, low level and align phase) introduced above.

Pulse Width/Duty Cycle

Pulse Width is defined as the time from the 50% threshold of a rising edge amplitude to the 50% threshold of the next falling edge amplitude as shown in the figure above.

Pulse Width range is limited by the “Minimum Pulse Width” and the “Pulse Period” (for the ranges of “Minumum Pulse Width” and “Pulse Period”, please refer to “Signal Characteristics” in Specifications). The default value is 500μs.

 Pulse Width ≥ Minimum Pulse Width  Pulse Width ≤ Pulse Period - Minimum Pulse Width × 2

Pulse Duty Cycle is defined as the percentage that the Pulse Width takes up in the whole period.

Pulse Width and Duty Cycle are correlative. Once a parameter is changed, the other will be automatically changed. 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 - 2 × Minimum Pulse Width ÷ Pulse Period)

Press Width/Duty to highlight “Width”, and use the numeric keyboard or direction keys and knob to input the desired value. Then, select the desired unit from the pop-up menu.

 For the input method of the value, refer to the introduction in Parameter

Setting Method.

 Selectable Pulse Width units: sec, msec, μsec, nsec.  Press this softkey again to switch to duty cycle setting (at this point, it is set to

20% automatically).

Leading/Trailing Edge Time

The Leading (rising) edge time is defined as the duration of the pulse amplitude rising from 10% to 90% threshold, while the Trailing (falling) edge time is defined as the duration of the pulse amplitude moving down from 90% to 10% threshold as shown in the figure above.

The range of leading/trailing edge time is limited by the currently specified pulse width limit as shown in the formula below. DG4000 will automatically adjust the edge time to match the specified pulse width if the value currently set exceeds the limit value.

Leading/Trailing Edge Time ≤ 0.625 × Pulse Width

Press Leading (or Trailing) to highlight the softkey. Use the numeric keyboard or direction keys and knob to input the desired value and select the desired unit from the pop-up menu.

 For the input method of the value, refer to the introduction in Parameter

Setting Method.

 Selectable Leading/Trailing Edge Time units: sec, msec, μsec, nsec.  Leading edge time and trailing edge time are independent from each other

and users can set them separately.

1. Cycle Period

Press this softkey and use the numeric keyboard or direction keys and knob to set the cycle period of the new waveform. Cycle period is the boundary time of the waveform and the range is from 25.0ns to 1Ms. Note that the time of the last point that can be defined should be lower than the cycle period.

2. High VLimit

Press this softkey and use the numeric keyboard or direction keys and knob to set the level upper limit of the new waveform. The level upper limit is the maximum voltage that can be set during waveform edit. The level upper limit must be greater than the “Low VLimit” currently set and lower than or equal to +5V (50Ω).

3. Low VLimit

Press this softkey and use the numeric keyboard or direction keys and knob to set the level lower limit of the new waveform. The level lower limit is the minimum voltage that can be set during waveform edit. The level lower limit must be greater than or equal to -5V (50Ω) and lower than the “High VLimit” currently set.

4. Init #Points

When creating a new waveform, the waveform editor will automatically create a waveform with two points. By default, point 1 is located at 0 seconds and point 2 at half of the specified cycle period. In addition, the levels of the two points are equal to the specified “Low VLimit”. Press this softkey and use the numeric keyboard or direction keys and knob to set the initial points of the new waveform. DG4000 allows users to create arbitrary waveform with 1 to 16384 (16K) points. If in need, you can “Insert Point” or “Delete Point” later.

Overview

According to Fourier transform, time domain waveform is the superposition of a series of sine waveforms as shown in the equation below:

Generally, component with

fundamental waveform frequency,

is fundamental waveform phase. The frequencies of other components (called

harmonics) are all integral multiples of the fundamental waveform frequency. Components whose frequencies are odd multiples of the fundamental waveform frequency are odd harmonics and components whose frequencies are even multiples of the fundamental waveform frequency are even harmonics.

DG4000 can output up to 16th order of harmonic. After selecting CH1 or CH2, press Harmonic at the front panel to enter the harmonic setting menu. Users can set the parameters of fundamental waveform, set the type of harmonic, specify the highest order of harmonic and set the amplitude and phase of each order of harmonic.

After finishing harmonic parameter setting, press Output1 or/and Output2 and the backlight of the button turns on, the instrument outputs the specified harmonic from the corresponding output terminal.

16 bits binary data is used to represent the output status of the 16 orders of harmonics respectively, wherein, 1 represents enabling the output of the corresponding harmonic and 0 represents disabling the output of the corresponding harmonic. Users only need to use the numeric keyboard to modify the value of each data bit (note: the leftmost bit representing fundamental waveform is always X and can not be modified). For example, set the 16 bits data to X001 0000 0000 0001, thus 4th and 16th orders of harmonics are output.

Note: the actual harmonics output is determined by the “Order” currently specified.

Modulated waveform usually consists of carrier waveform and modulating waveform. For amplitude modulation (AM), the amplitude of the carrier waveform varies with the instantaneous voltage of the modulating waveform.

To Select AM Modulation

Press Mod  Type  AM to enable AM function.

 When Mod is enabled, Sweep or Burst will be disabled automatically (if

enabled currently).

 After AM is enabled, the instrument will generate AM waveform with the

currently specified carrier and modulating waveforms.

To Select Carrier Waveform Shape

AM carrier waveform could be Sine, Square, Ramp or Arbitrary waveform (except DC). The default is Sine.

 Press the front panel key Sine, Square, Ramp or Arb Select Wform (or

User, the pre-defined waveform can not be DC) to select a desired carrier

waveform shape.

 Pulse, Noise and DC could not be used as carrier waveform.

To Set Carrier Frequency

Different carrier waveforms have different frequency ranges as shown in the table below. For all the carrier waveforms, the default value is 1kHz.

 Input the desired frequency value using the numeric keyboard or direction

keys and knob.

 The modulating waveform frequency ranges from 2mHz to 50kHz, and the

default value is 100Hz. Notice that, this menu will be grayed out and disabled when external modulation source is selected.

To Set Modulation Depth

Modulation depth expressed as a percentage indicates the amplitude variation degree. The AM modulation depth ranges from 0% to 120%. Press AM Depth to set AM modulation depth.

 In 0% modulation, the output amplitude is half of the specified value.  In 100% modulation, the output amplitude is equal to the specified value.  In >100% modulation, the output amplitude of the instrument would not

exceed 10Vpp (50Ω load).

When “Ext” modulation source is selected, the output amplitude of the instrument is also controlled by the ± 2.5V signal level at the [Mod/FSK/Trig] connector at the rear panel. For example, set the modulation depth to 100%, the output amplitude is the maximum when the modulating signal is +2.5V and the minimum when the modulating signal is -2.5V.
