Hi Justin,
Thanks for your answer.
Just to be sure, for the NF measurment, what is the setup ?

For 500MHz central frequency, I use 10 MHz bandwidth, the reference level to -50dBm.
I just put a marker noise at 501 MHz and read the value ?
I do not have to set the trace in average mode ?

Cause the 501MHz value I found is only 9.2 dB NF instead of the 16.55 dB calculate from your DANL worst case spec.
I always have margin between the datasheet of my systems and the reality, but here it is quite crazy.
Best regards

Hello, I have the same hot temperature problems (49.9 degree for 25 degree external).
I do not understand how it should work @65 degree external

Another point on the USB connection of the BB60C
We need to use our BB60C on differents tests installation with different distance from the computer.
Sometime need bulkhead interface, the fact that the BB60C have a correct connexion (and not made USB connection / USB disconnection / USB connection…. as long as we try to connect) is more depending of chance or magical way.
We have now 4 BB60C, and they do not with all our cabling, depending of something we do not understand.

We have think in the past we have understand and could be fine in any case. But after buy a new one, we discover that this new part work on a cabling, but not on the two other.

The fact is, the BB60C is always working with the useless delivered Y cable. But as you try whit another cable or lenght, this is onther story.

We now use type C cable, but it still be sensitive.
From where could come the problem, as we solve the power issue ?

Ok, I search a way to present an alarm to protect the BB60C in case of high temperature, what is the maximum for internal temperature in this case.

I suppose that you have tested in your environmental chambers at 65’C and -40’C and have the internal temperature results ?
