General
Frequency accuracy	± 20 ppm

The GX310 function generator from Metrix is a multifunctional signal generator designed for the generation of precise electrical signals in the frequency range from 0.001 Hz to 10 MHz. It is based on DDS technology (Direct Digital Synthesis), which enables high frequency accuracy and stability. This technology ensures that the generated signals remain stable over long periods and exhibit only minor deviations, which is crucial for precise measurement and testing applications. Frequency setting is performed with high accuracy to the last digit, allowing fine adjustment of signals to specific requirements.

Applications

The GX310 is suitable for a wide range of applications in the fields of measurement technology, electronics development, and laboratory environments. It is frequently used for signal transmission, circuit testing, simulating input signals for electronic devices, or analyzing frequency behavior. The ability to generate various signal waveforms such as sine, triangle, square, LOGIC, and TTL makes it flexible for use in different technical contexts.

Functions and Equipment in Detail

The generator provides the generation of five different signal waveforms: sine, triangle, square, LOGIC, and TTL. The LOGIC function allows direct setting of high and low levels, which is particularly useful for simulating digital signals. The sweep function (SWEEP) enables continuous frequency variation in linear or logarithmic form, with sweep time adjustable between 10 ms and 100 s. The signal waveform during the sweep can be selected as sawtooth or triangle signal. This function is useful, for example, in analyzing frequency response behavior or covering a frequency range.

Technology Explained Simply

The DDS technology works by digitally synthesizing signals, where a digital frequency control determines the output frequency. This results in high frequency accuracy of ± 20 ppm, meaning the actual frequency lies within a tolerance range of ± 20 parts per million of the set frequency. Signal output is provided via an output protected against overvoltage up to 60 V DC or 40 V AC, enabling safe operation even in case of incorrect use. Calibration is performed via the front panel of the device, without requiring the housing to be opened.

Compatibility and Accessories

The GX310 is also available as a programmable version GX310-P, which features a USB interface and supports the SCPI protocol. This enables remote control of the device via a PC, which is advantageous for automated measurement processes or integration into larger test systems. External frequency measurement is performed via an integrated frequency counter capable of measuring frequencies from 5 Hz to 100 MHz. This extends the functionality of the device, as it not only generates signals but can also measure external frequencies.

Mounting and Installation

The device is designed as a benchtop unit and is placed directly on a work surface. It requires no special mounting or installation. Operation is performed via the front panel with buttons and a large LCD display. Connections are located on the front side, enabling easy wiring.

Operational Advantages

The large LCD display with a digit height of 20 mm and a size of 125 x 45 mm ensures excellent readability. The display simultaneously shows key parameters such as VDC, VRMS, VPP, and the current signal waveform. Background illumination and contrast are individually adjustable, improving readability even in poorly lit environments. The combination of high accuracy, versatile signal waveforms, and remote control capability makes the GX310 a powerful tool for professional users.
