| Here are some of the requested measurements: http://www.dd-wrt.com/phpBB2/viewtopic.php?t=22201 I put them in a new thread because they are not really related to the orginial topic of this thread. I ... |

Forum: Broadcom SoC based Hardware Posted: Thu Oct 25, 2007 2:32 Subject: WHR-HP-G54 Transmitter power measurements |
| I promised a number of people on this forum that I would measure the TX (transmit) power of a Buffalo WHR-HP-G54. These measurments were made in the same manner as the measurements in this I first ... |

| tkoyn, I will certianly test the WHR-HP-G54 as you have requested. You'll have to have a little patience though. My WHR-HP-G54s got installed yesturday, so I cannot make the measurements until ... |

| Thanks dicksons, I am just fortunate to have some experience in RF design, and have access to some decent test equipment. I hope I can contribute a just little bit to the dd-wrt community. I rea ... |

| I could not agree more GeeTek. There are a number of ways to measre and define TX power. So... here are a few photos of actual TX spectra and some spectrum analyzer measurements. The DD-WRT communi ... | |

| GeeTek, Unfortunately I do not have access to an oscilloscope that can look at the raw 2.4GHz voltages... However, you do raise a good point. A spectrum analyzer cannot measure the 'peak power' of ... |

| And finally (sorry for so many posts on this issue).... While I had the spectrum analyzer set up, I measured the TX power of a Linksys WRT54Gv8. Here are the results; 0mW setting = -16.2dBm output ... |

| Also, to address some discusssions that I have seen on the WHR-HP-G54... When I had one of these opened up, I measured the bias voltages to both the TX amplifier (labeled 'IC3') and the RX amplifier ... |

| Here yoiu go Bill; I measured the output of a WHR-HP-G54 with an Agilent E4404B spectrum analyzer. I tried this with DD-WRT V23, sp2 and V24, RC3. There was no difference. Here are the results; 0m ... |

| I hate to rain on the parade, but the test that WTS performed that shows the increadible TX powers is wrong. The Praxsym PM model test meters can only measure up to ~20dBm of forward power. If you w ... | |
