Analyzer Description
The HP 8753E is a high performance vector network analyzer for laboratory or production
measurements of reflection and transmission parameters. It integrates a high resolution
synthesized RF source, an S-parameter test set, and a four-channel three-input receiver to
measure and display magnitude, phase, and group delay responses of active and passive
networks.
Two primary and two auxiliary display channels and a large screen color display can show
the measured results of all channels, in Cartesian or polar/Smith chart formats. When the
auxiliary channels are enabled, all four S-parameters of a two-port test device may be viewed
simultaneously.
For information on options, refer to "Options Available" later in this chapter.
The analyzer has the additional following features:
Control
n
Measurement functions selection with front panel keys and softkey menus.
q
External keyboard compatibility that allows you to title illes and control the analyzer.
q
Internal automation, using test sequencing to program analyzer measurements and control
q
other devices without an external controller.
•I Test system automation with the addition of an external controller. This allows ail of the
analyzer's measurement capabilities to be programmed over the Hewlett-Packard Interface
Bus (HP-IB). (Refer to Chapter 11, "Compatible PeripheraWor the HP 87533 Network
A general purpose input/output (GPIO) bus that can control eight output bits and read five
q
input bits through test sequencing. This can be useful for interfacing to material handlers
or custom test sets.
Performance
n
Performance improvement through faster calculations, register recalls, and data transfers.
q
Automatic sweep time that selects the minimum sweep time for the given IF bandwidth,
q
number of points, averaging mode, frequency range, and sweep type.
Built-in service diagnostics are available to simplify troubleshooting procedures.
q
Measurement flexibility through trace math, data averaging, trace smoothing, electrical
q
delay, and accuracy enhancement.
Simultaneous viewing of all four S-parameters by enabling the auxiliary channels 3 and 4.
q
External source mode capability that allows you to phase lock the analyzer's receiver to an
q
external source. Refer to Chapter 6, "Applications and Operation Concepts."
Tuned receiver mode that allows you to use the receiver as a stand-alone device. Refer to
q
Chapter 6, "Applications and Operation Concepts"
Complete reflection and transmission measurements in either 50 or 75 ohm impedance
q
environments
Receiver/source frequency offset mode that allows you to set the analyzer's receiver and
q
source with a llxed frequency offset for mixer test applications.
Flash EPROM allows llrmware upgrades from the built-in disk drive.
q
Flat panel display and VGA output.
