Display control
Display formats
Single-channel, dual-channel overlay (both traces
on one graticule), dual-channel split (each trace
on separate graticules), three-channel split (each
trace on separate graticules), three-channel overlay
(three traces on one graticule), quad-channel over-
lay (four traces on one graticule), and quad-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 real and imaginary pairs. Occurs prior
to any formatting or port extensions.
Display annotations
Start/stop, center/span, or 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
graticules for easy viewing.
Electrical delay
Offsets 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 ±1 seconds.
Frequency blanking
Blanks out all frequency information on the dis-
play. Requires an instrument preset to re-enable
frequency 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
values of the display. Also, customize the color,
value, and brightness of the data traces, memory
traces, reference lines, graticules, text, and warn-
ing messages. 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
and recalled via the SAVE/RECALL menu. Instru-
ment 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.
Disk drive
Data, instrument states, user graphics, data plots,
and test sequences can be stored on internal floppy
disk in MS-DOS or Agilent’s standard LIF formats.
Data hardcopy
Data plotting
Hard copy plots are automatically produced with
HP-GL compatible digital plotters. Data plots can
also be stored directly to disk. The 8720ET/ES
family provides Centronics, RS-232C, and GPIB
interfaces.
Data listings
Printouts of instrument data are directly produced
with a printer such as the HP DeskJet or LaserJet.
Select black & white or color print. For a list of com-
patible printers, consult our printer-compatibility
