--- Quote from: dschiedsch on August 27, 2016, 05:41:17 am ---Not as interesting as you might expect. If you enter a wrong password for the service menu the analyzer just does nothing. It doesn't display a message like key invalid. I guess this string is used for the option licensing maybe? --- End quote --- Pressing SHIFT + TRANSIENT will also ask for a password. 882323 will not work. any clues what this password is? Thanks |

I also have this model analyzer. Documentation says they offered an "Option 5" Audio Demodulation. I wondered if it was just enabled through software or if it included some hardware. I had the front panel off a few days ago, and found the internal speaker is there, along with the headphone jack, and everything is wired up and therefore I think it is just a software option. |
