Agilent Technologies 8560E User Manual page 269

Displays the current coupling ratio between the
RBW/SPAN RATIO
resolution bandwidth and the frequency span. The ratio
is displayed in the active function block, and it is used
when resolution bandwidth is in coupled mode. The
ratio ranges from 0.002 to 0.10, in a 1, 2, 5 sequence.
The default ratio is 0.011.
Front-panel key access:
Activates the automatic local oscillator (LO) and
REALIGN LO & IF
intermediate frequency (IF) alignment routines. These
are the same routines that occur when
on. When REALIGN LO &IF is active, STOP REALIGN
appears and all other softkeys are blank during this
time. STOP REALIGN allows you to stop the IF
adjustment routine before it is finished; however the
routine is not stopped immediately. If STOP REALIGN
is activated, the amplitude accuracy of measurements
made by the instrument may not meet published
specifications.
Front-panel key access:
Accesses the softkeys that allow you to select the
REAR PANEL
signals at the rear-panel connectors. The 10 MHz EXT
INT softkey controls the J9 connector output. The
softkeys 0 → 10V LO SWP and .5 V/GHz (FAV) ( or
V/GHz .25 .50) select the signal that is present at J8.
Selections are not changed when
If the preselected external mixer mode is selected,
rear-panel output J8 is automatically switched to the
0.5 V/GHz (FAV) mode. The actual output at J8
becomes 1.5 V/GHz, referenced to the LO frequency.
The 1.5 V/GHz of the LO frequency is required for the
Agilent 11974 Series preselected external mixers.
Front-panel key access:
The VGA output port on the rear panel is always active
and does not require user interaction.
Accesses softkeys that allow you to recall stored
RECALL
instrument-state and trace data. The softkeys are:
POWER ON, LAST STATE, RECALL STATE, RECALL
TO TR A, and RECALL TO TR B.
