2. PRESENTATION
The GX 1030 is a dual-channel function/arbitrary waveform generator with specications of up to 30 MHz maximum bandwidth,
150 MSa/s sampling rate and 14-bit vertical resolution.
The proprietary EasyPulse technology helps to solve the weaknesses inherent in traditional DDS generators when generating
pulse waveforms, and the special square wave generator is capable of generating square waveforms with up to 30 MHz frequency
and low jitter.
With these advantages, GX 1030 can provide users with a variety of high delity and low jitter signals and can meet the growing
requirements of complex and extensive applications.

Standard interfaces: USB Host, USB Device(USBTMC), LAN (VXI-11)
LCD 4.3” display 480X272 points
2.2. OUTPUT CONNECTIONS
The function generator output circuits operate as a voltage source with an impedance of 50 ohms. At higher frequencies, an
incorrectly loaded output can cause errors without the output waveform. In addition, loads with an impedance less than 50 ohms
will reduce the amplitude of the waveform while loads with an impedance greater than 50 ohms will increase the amplitude of the
waveform.
Excessive distortion or errors caused by incorrect terminators are less noticeable at low frequencies, especially with sinusoidal or
triangular waveforms. Follow these precautions to ensure the integrity of the waveform :
Use 50 Ω coaxial cables and good quality connectors.
Make all connections as short as possible.
Use good attenuators, if necessary, to reduce the amplitudes of waveforms applied to sensitive circuits.
Use 50 Ω terminations or suitable impedance devices to avoid reection.
Make sure that attenuators and terminators can withstand the proper power.
If there is a DC voltage in the output load, use a serial coupling capacitor with the load. The time constant of the coupling capacitor
and the load must be long enough to maintain the pulse platitude.
2.3. IMPEDANCE ADAPTATION
If the wave generator is connected to a high impedance, such as an input impedance of 1 MΩ (in parallel with a capacitor) at the
input of an oscilloscope, connect the coaxial cable to a 50 attenuator, to a 50 Ω terminator and the oscilloscope. The attenuator
isolates the input capacity of the device and allows a correct adaptation of the output of the generator.

To Set the Duty Cycle
Duty Cycle: The ratio of the amount of time the pulse is in the high state and the waveform's period.
The Duty Cycle setting range is limited by the Frequency/Period setting.
For detailed information, please refer to specications.
The default value is 50 %
1. Press [Waveforms] → [Square] → [DutyCycle], to set the duty cycle.
The duty cycle shown on the screen when the instrument is powered on is the default value or the set value of last power down.
2. Input the desired Duty Cycle.
Use the numeric keyboard to input the parameter value directly and press the corresponding key to select the parameter unit. Or
use the arrow keys to select the digit to edit, and then use the knob to change its value. The generator will change the waveform
immediately.
