Hi Tom,
At 4GHz, using my E4406 to measure its output from -90dBm to +13dBm, it appears to be within 0.5dBm of indicated.
Above 13dBm the power doesn't increase and the UNLEVELED indicator comes on at about 14dBm.
Using my HP438A and HP8481H to do the same test gives a similar result but with an additional -1dB offset.
So its "close" :) ... well at least at 4Ghz
None of this kit has been calibrated in years so take the result with a grain of salt!
Given a bit of time I could write a labview thing to make some nice measurements and plots some graphs
regards
Tim

Hi Tim,
How accurate is the power output at 4GHz?

Hi Colby,
I can still change things via GPIB, no problem so far, my simple Labview(Student Edition) program still works :)
