Increasing the lower TG limit from -30dBm to -20dBm is a downgrade in my eyes. |

Does this mean an upgrade to the flush handle? --- End quote --- KD0RC: In a way you are correct, but it means that the next time you click on 'Clr Int Cal' you are going to loose the TG completely, NOT just its Calibration. BTW did you ever get your TG Calibration back? --- End quote --- Well, I see the X Scale (Log Lin) function when I hit the Span button, and that seems to work. If I hit the System button and go to page two, I see a new function, 'Sanitation'. Press it, and you get two options, OK and Cancel. Anyone have any idea what that does? (Anyone brave enough to click OK?) The tracking Generator output now goes from 0 to -20 dBm. Not sure why they changed this from -30 dBm. Wall-E - no, I do not have my TG cal back. I am hoping someone figures out a way to do the cal. Nothing that I have played with seems to have any effect. Service mode looks like it works the same - I don't see any new functions that look like they let you do a TG cal manually. |

The user data saved in the NVRAM and NorFlash are restored to factory settings. HOST NAME, IP address and password in LXI are restored to factory settings. |

For some high gain low noise preamps, -20dBm will be a very strong signal indeed. Yet more external attenuation I guess! |

Hello Guys, First of all: Happy New Year ... a little in advance but as many, family will keep me away from the forum for a while so ... ^-^ I've been trying the memory dump of my MSO1074Z, I'm using an OLIMEX JTAG header (the same model as referenced here by different members), I use MAC OS X and Windows 7 (Enterprise, 32 bits) without success (so far). Some of you have helped me to do some progress (thank you for that!), however still stuck; I should be doing some stupid thing I think |O I wanted to confirm with you, I was wondering if I should turn the oscilloscope ON when trying the dump (?) My problem seems to come from the USB driver for the OLIMEX header (in both MAC OS X and Windows) I used the zadig (ver 2.1.1) tool (in the Windows environment, which is a real one not a virtual machine) to install the drivers (tried the three proposed by the tool) and I had the same error message: no device found. In the MAC is not any better, I installed and locally compiled several tools without any success. Any suggestion ? I really don't care which OS can make it, I'm using these two basically because is what I have at home, I could even use Linux virtual machines (I have Debian and Fedora already installed and running) but considered that if with the real hardware I'm not getting good results adding and extra layer of complexity wouldn't help at all. Any advice will be appreciated! Gus |
