???Dual-channel Function: maximum output frequency 30MHz (sine wave), 250msa/s sampling rate, 14bits vertical resolution. High Reliability: DDS direct digital synthesis technology is used to produce accurate, stable and low distortion output signals. Large-scale integrated circuit, surface mount technology, high reliability and has long service life. ???High Frequency Accuracy: frequency accuracy can reach 10-6 orders of magnitude. And the full-range frequency resolution is 1?Hz(0.000001Hz). Continuous Adjustable Pulse Width and Frequency of Pulse Wave: the adjustment range is 20ns-1s. The pulse amplitude can be continuously adjusted between 0~10V, and the adjustment accuracy is 0.001V. No Range Limit: the full range of frequency is not divided into gear switches, program-controlled settings. ???Burst Output Function: there has manual trigger, internal CH2 trigger, and external trigger for your options, it can output 1~1048575 pulse trains. Arbitrary Waveform Editing Function: it can edit arbitrary waveform on PC and download to instrument output waveform. Storage Feature: it can be store 20 groups of instrument state parameters set by users, and call up and reappear at any time. ???Compact & Safety: the device adopts the embedded panel design of ABS plastic shell, which is convenient to integrate with user's equipment and easy to install. All signal outputs can work under load short-circuit conditions 60s or more. Scanning Function: it can scan the four properties of the signal: frequency, amplitude, offset, and duty cycle. And has two scanning modes: linear scan and logarithmic scan. The scan time can reach 999.99s, the start and end of the scan can be set arbitrarily. ???Display Screen: using the 3.2-inch (320*240) color screen to display the waveform parameters of two channels at the same time. Dual Channel Output: fully independent dual channel output (equivalent to two independent signal sources), which can work synchronously and the phase difference can be precisely adjusted. Standard Channel Tracking Function: when tracking is turned on, all parameters of the two channels can be updated according to the user's configuration at the same time.
