Agilent / HP / Keysight 8714ES

The Agilent/HP 8714ES features an S-parameter test set with full two-port vector-error correction, providing complete and accurate measurements of device S-parameters.

The Agilent 8714ES has two independent channels that can measure and display two parameters such as S21 (transmission) and S11 (reflection) in a variety of formats including delay and SWR, on rectangular, polar or Smith-chart displays.

The Agilent 8714ES supports Log or linear magnitude, SWR, phase, group delay, real and imaginary, Smith chart, polar, and impedance magnitude formats.

Measurement data can be compared to any combination of line or point limits for pass/fail testing. User defined limits can also be applied to an amplitude- or frequency reference marker. A limit-test TTL output is available on the rear panel of the 8714ES for external control or indication. Limits are only available with rectilinear formats.

In 8714ES, each measurement channel has eight markers. Markers are coupled between channels. Any one of eight markers can be the reference marker for delta-marker operation. Annotation for up to four markers can be displayed at
one time.

Markers can be used in absolute or delta modes. Other marker functions include marker to center frequency, marker to reference level, marker to electrical delay, searches, tracking, and statistics.

The marker-tracking function of the 8714ES enables continuous update of marker search values on each sweep. Marker statistics enable measurement of the mean, peak-to-peak and standard deviation of the data between two markers. For rapid tuning and testing of cable-TV broadband amplifiers, slope and flatness functions are also available.

The 8714ES allows saving trace data, instrument states (including calibration data), and IBASIC programs on floppy disks using the built-in 3.5 inch disk drive.

The 8714ES allows making hardcopy prints using PCL and PCL5 printers or Epson-compatible graphics printers.

The 8714ES analyzer can be controlled by sending SCPI within a telnet session or via a socket connection and TCP/IP (the default socket port is 5025). The analyzer's socket applications programming interface (API) is compatible with Berkeley sockets, Winsock and other standard socket APIs.

With SICL/LAN, the 8714ES analyzer is controlled remotely over the LAN with the same methods used for a local analyzer connected directly to the computer via a GPIB interface.
