Carrier Wave Frequency Setting

Settable carrier wave frequency range is different for different carrier waveforms. Default frequency of all carrier wave is 1kHz. The frequency setting range of each carrier wave can be seen in the following table:

If need to set carrier frequency, please press Parameter→ Frequency softkey, then enter required numerical value, and select unit after selecting carrier waveform.

Modulation Source Selection

This device can select internal modulation source or external modulation source. After enabling AM function, the default modulation source is internal. If need to change press Parameter→ModulationSource→External in turn.

1) Internal Source

When modulation source is internal, modulation wave can be: sine wave, square wave, rising ramp wave, falling ramp wave, arbitrary wave and noise. After enabling AM function, the default of modulation wave is sine wave. If need to change it, press Carrier Wave →Parameter→Type in turn.

Page 25

UTG1000A Series Function Generator User Manual

 Square wave: duty cycle is 50%  Rising Ramp Wave: symmetry degree is 100%  Falling Ramp Wave: symmetry degree is 0%

 Arbitrary Wave: when arbitrary wave is modulated waveform, DDS function generator

limits arbitrary wave length as 1kpts in the way of random selection

 Noise: White Gauss noise

2) External Source

When modulation source is external, parameter list will hide the modulation wave option and modulation frequency option, and carrier waveform will be modulated by an external waveform. AM modulation depth is controlled by ±5V signal level of external modulation input terminal. For example, if modulation depth value is set to 100%, AM output amplitude is the maximum when external modulation signal is +5V, AM output amplitude is the minimum when external modulation signal is -5V.

Modulation Shape Frequency Setting

When modulation source is internal, frequency of modulation shape can be modulated. After enabling AM function, range of modulation wave frequency is 2mHz~50kHz (default is 100Hz). Press Parameter→Modulation Frequency to change. When modulation source is external, parameter list will hide the modulation shape option and modulation frequency option, and carrier waveform will be modulated by an external waveform. The range of modulation signal input from external is 0Hz~ 20Hz.

Modulation Depth Setting

Modulation depth indicates the extent of amplitude variation and is expressed as percentage. Suitable setting range of AM modulation depth is 0% to 120%, and the default is 100%. When modulation depth is set to 0%, the constant amplitude (a half of the carrier wave amplitude that has been set) is output. Output amplitude changes as modulation waveform changes when modulation depth is set to 100%. The instrument output a peak-peak voltage less than ±5V (is connected with 50Ω terminal) when modulation depth is more than 100%. If need to change, press Parameter→Modulation Depth in amplitude function interface.

The default of start frequency is 1kHz, and stop frequency is 2kHz. Different sweep waveform has different settable range of enabling and stop frequency, settable frequency range of each sweep wave are shown in the following table:

Page 75

UTG1000A Series Function Generator User Manual

4.2.3 Sweep Mode

Linear sweep: waveform generator changes output frequency in the linear way during the sweep; Logarithmic sweep: waveform generator changes output frequency in logarithmic way; External sweep, the default is linear sweep way, if need to change, please press Type Logarithm softkey.

4.2.4 Sweep Time

Set the required time from initial frequency to terminal frequency, the default is 1s, and the settable range is from 1ms to 500s. If need to change, press Parameter →Sweep Time softkey in turn, then enter number with number keyboard, and press corresponding unit softkey

4.2.5 Trigger Source Selection

When signal generator receives a trigger signal, it generates a sweep output, and then waits for the next trigger signal. Sweep source can be internal, external or manual trigger. If need to change, press Parameter →Trigger Source softkey in turn.

1) When internal trigger is selected, waveform generator will output a continuous sweep, and the rate

Page 76

UTG1000A Series Function Generator User Manual

is determined by sweep time.

2) When external trigger is selected, waveform generator will trigger through modulation interface

hardware.

3) When manual trigger is selected, backlight of Trigger button will flash, press Trigger button for once,

sweep will be output.

4.2.6 Trigger Output

When trigger source is internal or manual trigger, trigger signal (square wave) can be output through

external modulation interface (Input/CNT probe). The default of trigger output option is “Close”. If need to change, press Parameter→Trigger Output →Open softkey in turn.

 In internal trigger, signal generator output a square of 50% duty cycle through external modulation

interface (Input/CNT probe) at the beginning of sweep.

 In manual trigger, signal generator output a pulse that has pulse width more than 1us through

external modulation interface (Input/CNT probe) at the beginning of sweep.

 In external trigger, trigger output is output through modulation interface (Input/CNT probe), but

trigger output options in parameter list will be hid.

4.2.7 Comprehensive Example

In sweep mode, set a sine wave signal with 1Vpp amplitude and 50% duty cycle as sweep signal, and sweep way is linear sweep, set the initial frequency of sweep to 1kHz and terminal frequency to 50kHz and sweep time to 2ms. Use rising edge trigger of internal source to to output sweep wave. Specific steps are seen as following:

1) Enable Sweep Function

Press Menu→Sweep→Type→Linear in turn to start the Sweep function.

General Maintenance

 Do not store or place the instrument and liquid crystal display in direct sunlight.  To avoid damaging instrument or probe, do not spray fog, liquid or solvent on the instrument or

probe.

Cleaning and Maintenance

 Clean the the instrument according to the using situation.  Please disconnect the power supply, then with a damp but not dripping soft cloth, wipe the

instrument (it is suitable to use mild cleaning agent or water to wipe the dust on instrument, do not use chemistry or cleaning agent with potent substances like benzene, toluene, xylene, acetone, etc.) to wipe the dust off probes and the instrument.

 When cleaning the LCD screen, please pay attention and protect the LCD screen.  Do not use any chemical abrasive cleaning agent on the instrument.

Warning: Please confirm that the instrument is completely dry before use, to avoid damage and personal injury caused by electrical short circuit caused by moisture.
