Agilent / HP / Keysight 8719ET

The Agilent/HP 8719ET Transmission/reflection vector Network Analyzer is an instrument which measures the complex transmission and reflection characteristics of two port devices in the frequency domain.

The 8719ET does this by sampling the incident signal, separating the transmitted and reflected waves, and then performing ratios that are directly related to the reflection and transmission coefficients of the two port.

Frequency is swept to rapidly obtain amplitude and phase information over a band of frequencies of interest.

The 8719ET Network Analyzer utilizes synthesized frequency sources to provide a known test stimulus that can sweep across a range of frequencies or power levels.

The 8719ET also can perform ratioed measurements (including phase), which require multiple receivers.

The 8719ET can provide a wealth of knowledge about a device under test (DUT), including its magnitude, phase, and group-delay response.

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.

Test sequences can be stored internally in RAM, to an internal or external disk drive, or loaded from a computer over the GPIB interface. Sequence 6 is saved in nonvolatile storage and can be used as an autostart routine when titled AUTO.

Each display channel of the 8719ET has five independent markers that can be displayed simultaneously. Twenty independent markers can be displayed in the 4-channel display mode when markers are uncoupled.
