Display control
Display formats
Single channel dual channel overlay (both traces
on one graticule), dual channel split (each trace on
separate graticules).
Trace functions
Display data
Display current measurement data, memory data, or
current measurement and memory data simultaneously.
Trace math
Vector division or subtraction of current linear
measurement values and memory data.
Display annotations
Start/stop, center/span, CW frequency, source
level, scale/div, reference level, marker data, soft-
key functions, warning and caution messages, trace
identification, and pass/fail indication.
Reference position
Ranges from the 0 (bottom) to 10 (top) graticule
position.
Autoscale
Automatically selects scale resolution and refer-
ence value to center the trace on the display gratic-
ules for easy viewing.
Electrical delay
Offset measured phase or group delay by a defined
amount of electrical delay, in seconds. Operates
similarly to an electronic line stretcher. Amount of
electrical delay can range between ±l seconds.
Frequency blanking
Blank out all frequency information on the display.
Requires an instrument preset to re-enable fre-
quency information on the display.
Title
Add custom titles (49 characters maximum) to the
displayed measurement. Titles will be plotted when
making hardcopies. Titles can also be used to dis-
play operator messages or prompts for a manual
adjustment during a test sequence.
Adjust display
Control the intensity and background intensity val-
ues of the display. Also, customize the color, value,
and brightness of the data traces, memory traces,
reference lines, graticules, text, and warning mes-
sages. Default colors can be recalled along with
one set of user-defined display values. Control is in
% of full range.
Save/Recall storage
Instrument state
Up to 31 instrument states can be stored internally
or recalled via the SAVE/RECALL menu. Instrument
states include all control settings, active limit lines,
active list frequency tables, memory trace data,
active calibration coefficients, and custom display
titles. Storage is in non-volatile memory.
Test sequences
Six measurement sequences can be stored or
recalled via the sequencing menu. Sequences may
also be recalled from Preset menu. Sequence regis-
ter 6 is part of non-volatile storage and is not erased
during a power cycle. If sequence 6 is titled AUTO, it
will be executed when power is switched on.
Disk drive
Data, instrument states (including calibration
data), user graphics, data plots (HP-GL commands),
and test sequences can be stored on disk, using the
analyzer’s built-in disk drive or any external disk
drive with command subset CS/80. Data files can
be stored in MS-DOS format or Hewlett-Packard’s
standard LIF format in binary or ASCII formats
(compatible with the Agilent 85150A microwave
design system). A disk to be used for data storage
can be initialized directly by the analyzer.
Data hardcopy
Data plotting
Hard copy plots are automatically produced with
HP-GL compatible graphics printers such as the HP
DeskJet or LaserJet (in single color or multi-color
format). The analyzer provides Centronics, RS-232C,
and GPIB interfaces.
Configure plots
Configure plots completely from the network ana-
lyzer by defining pen color and line type for data,
text markers, graticules, and memory traces.
Functions
Plot trace(s), graticule(s), markers(s), or text
including operating and system parameters.
Quadrants
Plot entire display fullpage sized or in one of four
different quadrants of the plotter paper.
Data listings
Printouts of instrument data are directly produced
with a printer such as the HP DeskJet 520, LaserJet,
or 560C or PaintJet 3630A. Select a standard (sin-
gle color) or color print. Printouts can include
either the graphical display image (excluding soft-
key label), or lists of numeric data; one line per
stimulus point, with up to five columns defined by
currently active parameters.
