SGL, FREE RUN, VIDEO, LINE, EXTERNAL, and
TRIG POL POS NEG. When any mode other than
FREE RUN is selected, a T appears in the special
functions area at the left side of the display screen.
Front-panel key access:
Sets the sweep to trigger on the rising edge (POS)
TRIG POL POS NEG
or the falling edge (NEG) of the trigger signal.
Front-panel key access:
Selects amplitude units automatically (AUTO) or
UNITS AUTO MAN
manually (MAN). When in AUTO mode, the default
units are dBm (in log scale) or VOLTS (in linear scale).
The units available from this menu are: dBm, dBµV,
dBmV, VOLTS, WATTS.
Front-panel key access:
Displays the current coupling ratio between the video
VBW/RBW RATIO
bandwidth and the resolution bandwidth. The ratio is
displayed in the active function block, and is used when
the two bandwidths are in coupled mode. The ratio
ranges from 0.003 to 3, in a 1, 3, 10 sequence. The
default value is 1.
Front-panel key access:
For Agilent 8564E/EC and Agilent 8565E/EC only.
V/GHz .25 .50
Specifies a 0.25 or 0.5 volts per GHz sweep output at
the rear-panel connector J8. This is also referred to as
the frequency analog voltage (FAV). Connector J8 is
labeled LO SWP|FAV OUTPUT. When using a 8560
E-Series or EC-Series with a tracking generator such as
an Agilent 85640A, this softkey must be activated and
set to 0.5 V/GHz. Pressing
selection of FAV as the output for J8.
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.
