The Instek AFG-4125AE Single Channel Arbitrary Function Generator with Amplifier is equipped with a large 8" LCD display. This entry-level model has a frequency bandwidth of 25MHz and a sampling rate of 125MSa/s. It provides a high resolution of 1Hz and has built-in standard waveforms such as sine wave, square wave, triangle wave, pulse wave, noise wave, harmonic wave, etc. For vertical resolution, it provides 14-bit resolution. In addition, it provides an arbitrary waveform editing function with 16k memory depth.

8" Touch Screen Display

The AFG-4000 series is equipped with an 8-inch high-resolution TFT LCD, and models above 35MHz are equipped with the touch screen function. The configuration of touch screen makes inputting parameters more convenient. Users only need to touch parameters such as Frequency, Amplitude or DC offset, and a numeric input window will appear on the screen. Users can intuitively input parameters through this window or the numeric keys on the AFG-4000 panel. Through the 8" large screen, touch screen and diverse built-in waveforms, users can control it at will to meet their signal generation needs. As for the interfaces, this 25MHz model has built-in USB Host/Device interfaces.

Harmonic Signal Generator

The harmonic signal generator can simulate the harmonic signal of the switching power supply and test the characteristics of the EMI power filter. Users can set the amplitude and phase of each order signal to achieve the desired signal. The AFG-4000 series can set and generate up to 16th order harmonics.

Rich Built-In Arbitrary and Modulation Waveforms

Users can use the built-in 146 application arbitrary waveforms for signal editing and output. The built-in waveforms include Common, Medical, Standard, or Math and Trigonometric, Window, Engineer, and Segmented Modulation related waveforms. From the panel, users can select built-in waveforms and edit, save, recall and output arbitrary waveforms.

The AFG-4000 series provides a wide range of modulation signals, including analog and digital modulation, such as AM, DSB-AM, FM, PM, PWM, ASK, PSK, BPSK, QPSK, FSK, 3FSK, 4FSK, OSK, SUM and other modulation signal outputs. Standard functions include Sweep and Burst outputs and the Counter function.

Provides Sweep, Burst, Counter Functions

Frequency sweeping function can be set to sine wave, square wave, triangle wave and arbitrary wave mode. Linear/logarithmic output can be set to meet various application requirements with different sweeping methods. Frequency sweep can test the frequency response of electronic components such as filters and low-frequency amplifiers, etc. It also supports N-cycle or Gate mode triggering, and can adjust its duration, operating frequency, waveform polarity and internal or external triggering to achieve discontinuous output related applications. It provides a 100mHz to 200MHz frequency counter function.

Built-In Power Amplifier

The AFG-4125AE has a built-in amplifier that can independently input/output 10W power. The amplification factor reaches 10 times to produce a maximum output of 22V. The independent input/output power amplifier provides a bandwidth range from 5Hz to 100 kHz, which can be used for audio signal as an audio amplifier. It can also be used for a power component characteristic test or as a drive amplifier for piezoelectric components (collocate with an impedance transformer, 10W output). Users can connect the AFG-4125AE's low-frequency amplifier to a speaker and use it as the driver source for the speaker, which is a common educational application.
