Agilent Technologies 83620B User Manual

Fltness Menu
When correction frequencies are arbitrarily spaced, the number of
interpolated points varies.
When utilizing the user atness correction feature, do not exceed
the swept signal generator ALC operating range. Exceeding the
ALC range causes the output p ower to become unleveled and
eliminates the b enets of user atness correction. The ALC range
can be determined by subtracting the minimum output power
( 0 20 dBm) from the maximum specied p ower. When the optional
step attenuator is ordered on a swept signal generator, at times it
may be necessary to uncouple the attenuator to obtain the full ALC
range. This can b e accomplished by selecting POWER [MENU]
[Uncoupl Atten]. For example, an Agilent 83620B has an ALC range
of  30 dB (  +10 to 0 20 dBm).
When user atness correction is enabled, the maximum settable test
port p ower is equivalent to the maximum available leveled power
minus the maximum path loss (P
o max
0 P
path loss
). For example,
if an 83620B has a maximum path loss of 15 dB due to system
components between the source output and the test port, the test
port p ower should b e set to 0 5 dBm. When user atness correction
is enabled, this provides the maximum available power to the device
under test (DUT).
Programming Codes
SCPI:
CORRection:FLATness f < num > [freq sux], < num > [DB] g 2*801
The portion of the ab ove command contained in fg can be
entered from one to 801 times. This command creates the
frequency-correction pair array similar to the front panel array.
The correction entered is at the asso ciated frequency and
frequencies in b etween are determined by linear interpolation.
CORRection:FLATness?
This command queries the atness array created with CORR:FLAT .
CORRection:ARRay[i] f < num > [DB] g 1601*1601
The portion of the ab ove command contained in fg must
be entered 1601 times. This array must contain 1601 evenly
spaced correction values. This command creates the 1601-p oint
correction set that has no equivalent front panel entry. If this
command is used to enter atness correction information the
CORRection:SOURce command (describ ed below) will be set to
array. There is an array for the foreground state (i=0) and for the
background state (i=1). If [i] is not sp ecied, the default is the
foreground state (i=0).
CORRection:ARRay[i]?
This command queries the entire 1601-p oint correction set.
