descriptionAN24632/5 1 Setup descriptionTests have been performed on the STw8009 application demo board (see AN2462), driven by the ST ARM DBB control board for I2C commands. Results have been recorded on an R&S FSU spectrum analyzer. As this device is dedicated mainly to RF (using 50R input impedance), a 25R serial resistor has been added, in order to have 75R real load for STw8009 output.The DBm values given are not absolute, they are as measured on 50R across 75R load. The captured screen copies show how the remaining energy level is relative to the in-band signal with and without low-pass filter.1.1 Selected video standard PAL BDGHIFigure 2.Green trace and blue trace schematic diagramRef 10 dBmAtt 35 dB ACenter20 MHzSpan40 MHz4 MHz/**RBW 10 kHzVBW 10 MHzSWT 400 ms*3 R MVIEW * 1 MVI E W PRN-90-80-70-60-50-40-30-20-10 0 10SWP 30 of 301 -19.88 dB m 4.423076923 MHz 2 -77.75 dB m 27.051282051 MHzDate: 7.NOV.2006 16:37:06AN2463Setup description 3/5The maximum in-band energy is around PAL features set forth in this document shall immediately voidany warranty granted by ST for the ST product or service described herein and shall not create or extend in any manner whatsoever, anyliability of ST.ST and the ST logo are trademarks or registered trademarks of ST in various countries.Information in this document supersedes and replaces all information previously supplied.The ST logo is a registered trademark of STMicroelectronics.
