Hi,
I have a E4407B and it has a 9k - 3GHz frequency response spec of +- .46 but the change from band 0 to band 1 happens before 3GHz and the amplitude drops 1.5db at the band change is this usual? Is there an allowance for this in
the specifications?
Thank you
The flatness specification for you unit in reference to 50 MHz is ± 1.5 db. If you see that the response is dropping, you will need an alignment. However, if the adjustment is too much due to excessive loss above 2.9 GHz you will fail DANL specifications. That is a sign that the 5087-7031 RHYTHM is going bad.
