HP 8753E supplemental characteristics, cont’d
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
nonvolatile memory.
Test sequences
Six measurement sequences can be stored or recalled
via the sequencing menu. Sequences may also be recalled
from Preset menu. Sequence register 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 turned on.
Disk drive
Data, instrument states (including calibration data),
user graphics, data plots (HP-GL commands), and test
sequences can also be stored on disk, using the HP 8753E’s
built-in disk drive or an external disk drive with command
subset CS/80. Data files can be stored in MS-DOS format
or Hewlett-Packard’s standard LIF format, which can be
read by a wide variety of computers, including the
HP 9000 series 300 and 400. Files can be stored in binary,
ASCII formats or Touchstone
© format (S2P). A disk to be
used for data storage can be initialized directly by the
HP 8753E.
Data hardcopy
Data plotting
Hard copy plots are automatically produced with
HP-GL compatible digital plotters such as the HP 7475A
and compatible graphics printers such as the HP DeskJet
or LaserJet (in single color or multi-color format). The
HP 8753E provides Centronics, RS-232C, and HP-IB
interfaces.
Data listings
Printouts of instrument data are directly produced with
a printer such as the HP DeskJet or LaserJet. Select a
standard (single color) or color print (with color printers).
For a list of compatible printers, consult our printer-
compatibility guide Web page. Its URL address is

Configure plots
Configure plots completely from the network analyzer by
defining pen color and line type for data, text markers,
graticules, and memory traces.
Functions
Plot trace(s), graticule(s), marker(s), or text including
operating and system parameters.
Quadrants
Plot entire display in one of four different quadrants of the
plotter paper.
System capabilities
Limit lines
Define test limit lines that appear on the display for go/no
go testing. Lines may be any combination of horizontal,
sloping lines, or discrete data points. Limit-test TTL output
available for external control or indication.
Operating parameters
Display, print or plot current instrument operating
parameters.
Transform
When time domain (Option 010) is present, selects the
Time Domain transform menu.
Harmonic measurements
When harmonic measurement (Option 002) is present,
selects the 2nd or 3rd harmonic measurement menu.
Instrument mode
Select external source, tuned receiver or frequency
offset mode.
External source mode
The receiver (input R) detects and phase-locks to any
externally generated CW signal. Receiver inputs A and B
will measure this same frequency for comparison or
tracking measurements.
• Automatic
The input signal frequency is counted and displayed.
• Manual
Measures the input signal closest to the frequency
specified by the user (within –0.5 to +5 MHz).
Tuned receiver
Tunes the receiver for a synthesized CW input signal
at a precisely specified frequency. The time bases of the
external RF source or sources must be tied to the external
reference input (rear panel BNC). The built-in RF source
is not used.
Frequency offset on/off
Sets the RF source to be swept at a fixed offset frequency
above the receiver as required in a swept RF/IF, fixed LO,
mixer test. The maximum delay between the RF source
and the R channel input is 0.3 microseconds. Frequency
offset mode has a 6 GHz maximum source limitation.
