Leader expands video analyzer set
July 22, 2005
On the LV5700A’s TFT screen, the delta is seen as a blue surround, as long as the R, G and B color components are within user-specified upper and lower limits. In this figure, the x-marks represent the upper signal level and the discs indicate the lower level. To see an enlarged version of this image, click here.
Leader Electronics has added new delta and bar-graph display modes to its line of LV5700A broadcast signal analyzers that enable users to assess color signal levels and recognize chroma gamut errors.
Displayed on the LV5700A's high-resolution TFT color screen, the delta is seen as a blue surround as long as the R, G and B color components are within user-specified upper and lower limits. If one or more color components exceed permitted maximum, the delta changes to red.
The LV5700A supports a variety of HD-SDI and SD-SDI signal formats. Analytical capabilities include transmission error detection, data dump display and voice control packet analysis.
Video sampling rate can be switched automatically between 74.25- and 74.25/1.001MHz in HD mode or to 13.5MHz in SD. The analyzer also incorporates analog NTSC/PAL composite and 525/625 component I/O. Two composite inputs and one switched output are provided. When operated in component mode, the LV5700A can display Y/Pb/Pr levels as RGB. Analog monitoring functions include picture, waveform and vector displays.
