![]() Another solution might be the ggggeffects-package, which provides utilities to build own plots. ![]() With the specs determined, I now have enough information to continue work on my project using this oscillator.You could build the plot by yourself, and then use a custom labeller-function. The update takes a little while, but once its done, youre ready to roll. This will update all of the latest telemetry data from online sources. Once you install and run it, the first thing that youll want to do is go into Edit and the Update TLE and select ' From Network '. Perhaps that was another thing that made this part a special order. Gpredict is available to download for Linux, Mac or Windows. A range of 6 dB matches the units on the spec sheet, but a 7 dBm minimum power is below that of any of the comparable modules. Power levels seemed to vary between 7 and 13 dBm across a wide range, however the analyzer calibration may be off somewhat. I didn't test the FM port, but I suspect it would yield the 310 kHz/mA seen on the AV-7403. This gave a tuning factor around 19 MHz/mA: in line with the specs of similar modules. At the upper end of 12.1 GHz, around 670 mA was needed. The lower edge of the specified range (7.9 GHz) was reached with approximately 450 mA. With 395 mA flowing, a signal finally popped up at around 7.2 GHz. ![]() As expected from this helpful document, a fair amount of tune current was required before oscillation started. The analyzer allowed me to see the frequency move around as I changed the current on the tuning port. Gpredict Build Full Path To You have to have PackageMaker.app installed either into a place where MacPorts expects it, or you need to set packagemakerpath to be the full path to and including PackageMaker.app, e.g., ApplicationsUtilitiesPackageMaker.app (but without the s). Before verifying the suspected power level, I used an inline attenuator to avoid any chance of damaging the machine. Satisfied that the module would behave somewhat as expected, I hooked it up to a spectrum analyzer. This makes the module's tuning behavior more like the next lower range, for example the AV-7403. The tune port measured 10Ω and the FM port measured 1Ω. To determine the likely power output, I hooked the oscillator into a dummy load, then measured the current draw on the 15V input - it was almost exactly 125 mA, which means it is probably a 30 mW (14.8 dBm) unit. ![]() The closest standard units appear to be the AV-7871 through AV-7873, which cover 8 to 12.4 GHz with several different power outputs. It matches the first pinout in this old spec sheet. The particular oscillator I received is marked with model number SO8-0354 and is labelled for 7.9 to 12.1 GHz. ![]()
