<FCnnn>
Command will increment or decrement the center frequency by the specified number
interpreted as pp 10
12
. The range of nnn for the
<FCnnn>
command is ±20000. Values
outside of that range are clamped at the maximal excursion either positive or negative.
Example:
<FC-10>
Functional Response: Center Frequency will decrement by –10×10
-12
Example Response:
" ...Persistent Frequency Adjustment = –10"
<FFnnn>
Command has identical function as
<FCnnn>
command, except it will increment or
decrement the Center Frequency by the specified number interpreted as pp 10
15
. The
range of nnn for the
<FFnnn>
command is ±20000000. Values outside of that range
are clamped.
Note:
<FC?>
and
<FF?>
return the current Center Frequency in 0.01 Hz.
<FDnnn>
Command will replace the digital adjustment value with the specified number inter-
preted as pp 10
12
. The range of nnn for the
<FDnnn>
command is ±20000. Values out-
side of that range are clamped at the maximal excursion either positive or negative.
Example:
<FD1000>
Functional Response: digital adjustment set to 1000×10
-12
Example Response:
" ...One Time Frequency Adjustment = 1000"
<FGnnn>
Command will replace the digital adjustment value with the specified number inter-
preted as pp 10
15
. The range of nnn for the
<FGnnn>
command is ±20000000. Values
outside of that range are clamped.
Note:
<FD?>
and
<FG?>
return the digital adjustment in pp 10
12
and pp 10
15
,
respectively.
<FEnnn>
Command will augment the digital adjustment, whereas the commands in the previous
section replaced the digital adjustment value.
<FEnnn>
will increment or decrement
the digital adjustment by the specified number interpreted as pp 10
12
. The range of nnn
for the
<FEnnn>
command is ± 20000. Values outside that range are clamped at the
maximal excursion either positive or negative.
Example:
<FE-500>
Functional Response: digital adjustment will decrement by –500×10
-12
Example Response:
" ...One Time Frequency Adjustment = –500"
<FHnnn>
Command will increment or decrement the digital adjustment by the specified number
interpreted as pp 10
15
. The range of nnn for the
<FHnnn>
command is ±20000000.
Values outside of that range are clamped.
Note:
<FE?>
and
<FH?>
return the digital adjustment in pp 10
12
and pp 10
15
,
respectively. They are redundant commands to
<FD?>
and
<FG?>
.
