About this Manual
We’ve added this manual to the Agilent website in an effort to help you support
your product. This manual is the best copy we could find; it may be incomplete
or contain dated information. If we find a more recent copy in the future, we will
add it to the Agilent website.
Support for Your Product
Agilent no longer sells or supports this product. Our service centers may be able
to perform calibration if no repair parts are needed, but no other support from
Agilent is available. You will find any other available product information on the
Agilent Test & Measurement website, www.tm.agilent.com.
HP References in this Manual
This manual may contain references to HP or Hewlett-Packard. Please note that
Hewlett-Packard's former test and measurement, semiconductor products and
chemical analysis businesses are now part of Agilent Technologies. We have
made no changes to this manual copy. In other documentation, to reduce
potential confusion, the only change to product numbers and names has been in
the company name prefix: where a product number/name was HP XXXX the
current name/number is now Agilent XXXX. For example, model number
HP8648A is now model number Agilent 8648A.

T o Use the Flatness C orrection Routine
When the F LA TNESS CORRECTION routine i s o n, the signal g enerator p e rforms a
calibration p ro cess that corrects for e xternal l osses or p o w er v ariations i n a n e xternal signal
path. In order t o u se FLA TNESS CORRECTION, the signal g enerator m ust rst r un the
CALIBRA TE FLA TNESS CORRECTION routine. During the CALIBRA TE FLA TNESS
CORRECTION routine, an HP 437B, H P 4 38A, H P 7 0100A, o r a SCPI compatible p o w er
meter, that is under con trol of the s ignal generator, measures p o w er v ariations at the output
of the external signal path o v er a u ser-dened frequency range. The signal generator then
reads bac k the p o w er lev el data from the p o w er meter a nd creates a table of correction
v alues for e ac h frequency p oin t ( the atness correction table). The atness c orrection table
is automatically stored in one o f f our n on-v olatile m emory registers. Up to four atness
correction tables can b e stored for l ater use.
When FLA TNESS CORRECTION i s o n, the atness correction t able adjusts the s ignal
generator output p o w er (to c omp ensate for losses or gains) to pro vide constan tl e v eled p o w er
at the external p ort.
