Sprolink SG-UHD 4K Ultra HD HDMI/3G-SDI Multi-Format Signal Generator

SG-UHD / Signal Generator
Signal generator is a device capable of producing various frequencies, waveforms, and output levels of electrical signals. It serves as a testing signal source or excitation source when measuring the amplitude characteristics, frequency properties, transmission properties, and other electrical parameters of various telecommunications systems or equipment, as well as when measuring the characteristics and parameters of components. Also known as a signal source or oscillator, the signal generator finds wide applications in production practices and the field of technology. So, fittingly, our SG-UHD is a professional-grade signal generator designed to provide 3G-SDI and HDMI2.0 4K signals, as well as optical fiber signals in the broadcasting and television industry.

Functions and features

Pattern measurement 1
Single color display or custom picture content is to test the color, temperature, grayscale, linearity, accuracy of the displayer. User-defined images can be imported as test graphs sample, built-in standard color bar, linear test pattern, grid pattern, monitor crosstalk test pattern sick signal or other professional test pattern, to meet the demand of debugging, testing, Test demand, IRE.

Pattern measurement 2
As a comprehensive audio, it supports up to 16 embedded AES/EBU audio channels, a -60dB to OdB dB range, and 20 to 20000Hz. The frequency sets the audio phase from 0.90,180 and 270 degrees. CH channel selection, a total of 16 routes SDI audio channels from CHO to CH15 can be switched freely. Switch-on, off, full on, full off, the four modes control the audio output of single channel or full channel Freq frequency lock, audio frequency can be from 20 to 20000Hz. DB value: arbitrary control of the output decibel size, covering -60dB to OdB value. Phase offset: audio phase can be set from 0.90,180 and 270 degrees respectively.

Channel Selection
There are 16 routes from CHO to CH15 of free switching of SDI audio channels.

Switching
Switch, on, off, full on, full off, the four modes control the audio output of single channel or full channel.

DB value input
arbitrary control of the output decibel size, covering -60dB to OdB value.

Phase offset
Set audio phase, audio phase can be set from 0.90,180 and 270 degrees.

Frequency locking

Auxiliary function
Different applications are supplemented by different schemes. The "Option" button of the device provides functions such as graphic overlay, time code, ring, border line, frame count, etc., which will help users analyze and test different signal formats. Time Code Supports linear Time code (LTC) and Vertical Interval Time code (VITC). Overlay: Select time code, border line, cross and garden through the function of image and text overlay. Moving: The image can be rolled from 4 different directions and the step size of the scroll can be set.

Loop superposition
Select Loop superposition by image overlay function.

Counter
Select the counter by the image overlay function.

Auxiliary line
Overlay the border line to check the completeness of the picture. Cross the center to check the position of the picture center.

Moving Direction
The image can be scrolled from 4 different directions and the scroll step size can be set.

Time Code
Supports linear time code (LTC) and Vertical interval Time code (VITC).
