hi
our DSA70000 has DPOJET tool, and the version is 2.1.1Build 8. so, does it need to be upgraded?

thanks
Jeff

again.
my current DPOJET version is 2.1.1 Build 8, i guess it is old requires updated, since phase noise label is not right. just want to confirm with you. 
another technique question is how to measure two clock sources' relative jitter? thanks

Hi Jeff,
Yes, there is a significantly newer version of DPOJET available.
DPOJET is updated together with the firmware of the machine. Here is the latest version of the firmware (and DPOJET): https://www.tek.com/en/support/software/firmware/firmware-dpo7000-dpo-dsa70000-dpo-dsa70000b-c-mso70000-c-doc-win-xp

On measuring relative jitter between two clock source's, that is possible by selecting a measurement like TIE, RJ or DJ, then going into "Configure", "Clock Recovery" and setting the Method to "Explicit clock - Edge" and selecting the desired clock channel.

hi Afonso,
i noticed that the latest version of the firmware you pointed to is released in 2012. so even i downloaded and installed it, the DPOJET version is still  the version is 2.1.1Build 8, and phase noise plot is still wrongly labelled by dBc/sqrt(Hz).
is there any newer version available? My machine is DSA70000B

thanks
JEFF

Hi Jeff,

That is my mistake, I'm sorry. DPOJET does not necessarily update with the firmware.
The latest DPOJET version for the DSA70000B can be downloaded here: https://www.tek.com/en/support/software/application/dpojet-dpo7000-dpo-dsa-mso70000-b-win-xp-v501-0

I downloaded the dpojet as you suggested, and it asked me to unintalled the old one, and when i click the installation, it required me to install DJAE package setup v5.0.0 or above before intsall DJA.

thanks
