User guide

Once a CNR calibration has been performed, the ratio can
be changed using the internal precision attenuator to vary
the noise power without degrading accuracy. The output
noise power level is factory calibrated at a 0 dB attenuator
setting and is displayed in dBm/Hz.
Every front panel operation except instrument on/off is
programmable, and the user can create up to nine test
routines that can run automatically under program con-
trol. These routines can include delay times and loops, and
can be executed manually or via bus control. The routines
are easily written using the program key, and information
on the display guides the user through the next steps.
