HP 8753E manual Analyzer Description, Control, Performance

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 RF 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:

nControl

qMeasurement functions selection with front panel keys and softkey menus.

qExternal keyboard compatibility that allows you to title illes and control the analyzer.

qInternal automation, using test sequencing to program analyzer measurements and control 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

Analyzer Programming Guide.)

qA general purpose input/output (GPIO) bus that can control eight output bits and read five input bits through test sequencing. This can be useful for interfacing to material handlers or custom test sets.

nPerformance

qPerformance improvement through faster calculations, register recalls, and data transfers.

qAutomatic sweep time that selects the minimum sweep time for the given IF bandwidth, number of points, averaging mode, frequency range, and sweep type.

qBuilt-in service diagnostics are available to simplify troubleshooting procedures.

qMeasurement flexibility through trace math, data averaging, trace smoothing, electrical delay, and accuracy enhancement.

qSimultaneous viewing of all four S-parameters by enabling the auxiliary channels 3 and 4.

qExternal source mode capability that allows you to phase lock the analyzer’s receiver to an external source. Refer to Chapter 6, “Applications and Operation Concepts.”

qTuned receiver mode that allows you to use the receiver as a stand-alone device. Refer to Chapter 6, “Applications and Operation Concepts”

qComplete reflection and transmission measurements in either 50 or 75 ohm impedance environments

qReceiver/source frequency offset mode that allows you to set the analyzer’s receiver and source with a llxed frequency offset for mixer test applications.

qFlash EPROM allows llrmware upgrades from the built-in disk drive.

qFlat panel display and VGA output.
