Introduction

All specifications and characteristics apply over a 25° C ±5° C range (unless otherwise stated) and 60 minutes after the instrument has been turned on.

Definitions

Specifications: Warranted performance. Specifications include guardbands to account for the expected statistical distribution, measurement uncertainties, and changes in performance due to environmental conditions.

Characteristics: A performance parameter that the product is expected to meet before it leaves the factory, but is not verified in the field, and is not covered by the product warranty. A characteristic includes the same guardbands as a specification.

Typical: Expected performance of an average instrument which does not include guardbands. It is not covered by the instrument’s warranty.

Nominal: A general, descriptive term that does not imply a level of performance. It is not covered by the instrument’s warranty.

Supplemental information: may include typical, nominal or characteristic values.

Calibration is the process of measuring known standards from a calibration kit to characterize a network analyzer’s systematic (repeatable) errors.

Corrected (residual) performance: Indicates performance after error correction

(calibration). It is determined primarily by the quality of the calibration standards and how well “known” they are, plus the effects of system repeatability, stability, and noise.

Uncorrected (raw) performance: Indicates performance without error correction (calibration). Uncorrected performance affects the stability of a calibration — the better the raw performance, the more stable the calibration.

b. These numbers apply for a measurement made using the “fine” bandwidth at an environmental temperature of 25° ±5° C.

c. The uncorrected directivity of a network analyzer is calculated in linear terms by dividing the reflection measurement of an ideal load by the average of the reflection measurements of an ideal short and an ideal open.

d. The uncorrected source match is the source match of the network analyzer when making a ratioed, uncalibrated measurement.

e. The uncorrected load match is the match of the network analyzer port used on the load side of a measurement.

f. Measured by setting output power to the maximum specified setting, connecting shorts to both ports, and measuring transmission.

Typical and specified crosstalk values are 5 dB worse than those shown in the table below 1 MHz (for all models) and above

2.2 GHz (for 8714ET/ES models).

37 a. Noise floor is defined as the RMS value of the trace (in linear format) for a transmission measurement in CW frequency mode, with

RF connectors terminated in loads, output power set to 0 dBm, and no averaging. The noise floor specifications and typicals for narrowband detection measurements assume that an isolation calibration has been performed using an average factor of 16. For the

8712ES/8714ES, external broadband detectors will provide a much lower noise floor than the internal broadband detectors.

b. The System Dynamic Range is calculated as the difference between the receiver noise floor and the minimum of either the source maximum output (maximum power setting minus output power level accuracy) or the receiver maximum input. System Dynamic

Range applies to transmission measurements only, since reflection measurements are limited by directivity. The System Dynamic

Range for 8714ET/ES 75

Ω analyzers is not a specification for frequencies >2 GHz; it is a characteristic. For the 8712ES/8714ES, external broadband detectors will provide much more dynamic range than the internal broadband detectors.

b. Center frequency is set to 1 GHz.

c. “Cycle Time” is the time required for the analyzer to finish one complete sweep cycle including the forward sweep (and reverse sweep when using two-port calibration), retrace, bandcrossings, and calculation time when in the “Continuous Sweep” mode.

d. This is the time to recall both the system state and calibration data.

e. “Data Transfer” is performed using an HP S700 workstation. The GPIB port is used to transfer “corrected” 64-bit, floating point numbers (real and imaginary).

f. A “Measurement Cycle” is defined as the time required for an HP S700 workstation to control the analyzer to: (1) recall the state and calibration (analyzer is now in “sweep hold” mode), (2) sweep (using the “:INIT1; *OPC?” command), and (3) transfer data.

This may be less than the sum of the other columns since a complete “Cycle Time” doesn’t need to be done for the controller to transfer data.

Data transfer times

The tables below show the various data transfer speeds that can be expected using different data formats.

Please note the following:

• ASCII data transfers are considerably slower than the other types.

• IBASIC CSUBs (compiled routines) can access trace data faster than an external computer.

• If only a few trace points need to be queried, using markers can be faster.

Measurement

Number of display measurements

Two measurement displays are available, with independent control of display parameters including format type, scale per division, reference level, reference position, and averaging. The displays can share network analyzer sweep parameters, or, by using alternate sweep, each measurement can have independent sweep parameters including frequency settings, IF bandwidth, power level, and number of trace points. The instrument can display a single measurement, or dual measurements on a split (two graticules) or overlaid (one graticule) screen.

Marker functions

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. Marker searches include marker to maximum, marker to minimum, marker to target value, bandwidth, notch, multi-peak and multi-notch. The marker-tracking function 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.

Storage

Internal memory

1.5 Mbytes (ET models) or 1 Mbyte (ES models) of nonvolatile storage is available to store instrument states, measurement data, screen images, and IBASIC programs.

Instrument states can include all control settings, limit lines, memory data, calibration coefficients, and custom display titles. If no other data files are saved in nonvolatile memory, between about 20 and 150 instrument states can be saved (depending on the model type and on instrument parameters). Approximately 14 Mbytes of volatile memory is also available for temporary storage of instrument states, measurement data, screen images, and IBASIC programs.

Trace functions

Current data, memory data, memory with current data, division of data by memory.

Display annotations

Start/stop, center/span, or CW frequency, scale per division, reference level, marker data, softkey labels, warning and caution messages, screen titles, time and date, and pass/fail indication.

Disk drive

Trace data, instrument states (including calibration data), and IBASIC programs can be saved on floppy disks using the built-in 3.5 inch disk drive. All files are stored in MS-DOS ® -compatible format. Instrument data can be saved in binary or ASCII format (including

Touchstone/.s1p format), and screen graphics can be saved as PCX (bit-mapped), HPGL (vector), or PCL5 (printer) files.

NFS

See description under Controlling via LAN

Limits

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 for external control or indication. Limits are only available with rectilinear formats.

Data markers

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.

Data hardcopy

Hardcopy prints can be made using PCL and PCL5 printers (such as HP DeskJet or LaserJet series printers), or Epson-compatible graphics printers. Single color and multicolor formats are supported. Hardcopy plots can be automatically produced with HPGL-compatible plotters such as the HP 7475A, or with printers that support

HPGL. The analyzer provides Centronics (parallel),

RS-232C, GPIB, and LAN interfaces.

Automation

Controlling via GPIB

Interface

The GPIB interface operates to IEEE 488.2 and SCPI standard-interface commands.

Control

The analyzer can either be the system controller, or pass bus control to another active controller.

Data transfer formats:

• ASCII

• 32- or 64-bit IEEE 754 floating-point format

• Mass-memory-transfer commands allow file transfer between external controller and analyzer.

Controlling via LAN

The built-in LAN interface and firmware support data transfer and control via direct connection to a 10 Base-T

(Ethertwist) network. A variety of standard protocols are supported, including TCP/IP, sockets, ftp, http, telnet, bootp, and NFS. The LAN interface is standard.

SCPI interface

The analyzer can be controlled by sending SCPI (standard commands for programmable instruments) 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. Socket programming can be done in a variety of environments including C programs, HP VEE, SICL/LAN, or a Java TM applet. A standard web browser and the analyzer's built-in web page can be used to remotely enter SCPI commands via a Java applet.

FTP interface

Instrument state and data files can be transferred via ftp

(file-transfer protocol). An internal, dynamic-data disk provides direct access to instrument states, screen dumps, trace data, and operating parameters.

HTTP

The instrument's built-in web page can be accessed with any standard web browser using http (hypertext transfer protocol) and the network analyzer's IP address. The built-in web page can be used to control the network analyzer, view screen images, download documentation, and link to other sites for firmware upgrades and

VXIplug&play drivers. Some word processor and spreadsheet programs, such as Microsoft ® Word 97 and Excel 97, provide methods to directly import graphics and data via a LAN connection using http and the network analyzer's

IP address.

SICL/LAN

The analyzer's support for SICL (standard instrument control library) over the LAN provides control of the network analyzer using a variety of computing platforms, I/O interfaces, and operating systems. With SICL/LAN, the 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. SICL/LAN protocol also allows the use of Agilent’s free VXIplug&play driver to communicate with the multiport test system over a

LAN. SICL/LAN can be used with Windows 95/98/NT ® , or

HP-UX.

NFS

The analyzer's built-in NFS (network file system) client provides access to remote files and directories using the

LAN. With NFS, remote files and directories (stored remotely on a computer) behave like local files and directories (stored locally within the analyzer). Test data taken by the network analyzer can be saved directly to a remote

PC or UNIX ® directory, eliminating the need for a remotely initiated ftp session. For Windows-based applications, third-party NFS-server software must be installed on the

PC. NFS is fully supported in most versions of UNIX.

Bootp

Bootstrap protocol (bootp) allows a network analyzer to automatically configure itself at power-on with the necessary information to operate on the network.

After a bootp request is sent by the analyzer, the host server downloads an IP and gateway address, and a subnet mask. In addition, the analyzer can request an IBASIC file, which automatically executes after the transfer is complete. For Windows-based applications, third-party bootp-server software must be installed on the PC. Bootp is fully supported in most versions of UNIX.

Programming with IBASIC

As a standard feature, all 8712ET/ES and 8714ET/ES net-

•

•

• work analyzers come with the Instrument BASIC programming language (IBASIC). IBASIC facilitates automated measurements and control of other test equipment, improving productivity. For simpler applications, you can use IBASIC as a keystroke recorder to easily automate manual measurements. Or you can use an optional, standard PC keyboard to write custom test applications that include:

Special softkey labels

Tailored user prompts

Graphical setup diagrams

• Control of other test instruments via the GPIB, serial, or parallel interfaces

Measurement calibration

Measurement calibration significantly reduces measurement uncertainty due to errors caused by transmission and reflection frequency response, source and load match, system directivity, and crosstalk. These analyzers feature factory-installed default calibrations that use vector-error correction, so that measurements can be made on many devices without performing a user calibration.

For greater accuracy, especially for test setups with significant loss or reflection, user calibrations should be performed. For reflection measurements, both one-port and two-port calibrations are available (two-port calibration requires an ES model). For transmission measurements, the following calibrations are available: normalization, response, response and isolation, enhanced response, and two port (two-port calibration requires an

ES model).

Calibration interpolation

Calibration interpolation is always active. The analyzer automatically recalculates the error coefficients when the test frequencies or the number of trace points have changed. The resulting frequency range must be within the frequency range used during the user calibration.

If this is not the case, the analyzer reverts to the factory default calibration. When calibration interpolation is used, the analyzer displays the C? annotation. System performance is not specified for measurements using calibration interpolation.

Available calibrations

ES models only

• Two-port calibration

Compensates for frequency response, source and load match, and directivity errors while making S-parameter measurements of transmission (S

21

, S

12

) and reflection

(S

11

, S

22

). Compensates for transmission crosstalk when the Isolation on OFF softkey is toggled to ON.

Requires short, open, load, and through standards.

ET and ES models: transmission measurements

• Normalization

Provides simultaneous magnitude and phase correction of transmission frequency response errors. Requires a through connection. Used for both narrowband and broadband detection (phase correction is not available in broadband mode). Does not support calibration interpolation.

• Response

Simultaneous magnitude and phase correction of frequency response errors for transmission measure ments. Requires a through standard.

• Response and isolation

Compensates for frequency response and crosstalk errors. Requires a load termination on both test ports and a through standard.

• Enhanced response

Compensates for frequency response and source match errors. Requires short, open, load, and through standards.

ET and ES models: reflection measurements

• One-port calibration

Compensates for frequency response, directivity, and source match errors. Requires short, open, and load standards.

Calibration kits

Data for several standard calibration kits are stored in the instrument for use by the calibration routines. They include:

3.5 mm (85033D) type-N 50 ohm (85032B/E) type-N 75 ohm (85036B/E) type-F 75 ohm (85039B)

7 mm (APC-7) (85031B)

In addition, you can also describe the standards for a user-defined kit (for example, open-circuit capacitance coefficients, offset-short length, or through-standard loss).

For more information about calibration kits available from Agilent, consult the 8712E Series Configuration

Guide, literature number 5967-6315E.

Key options

75 ohms (Option 1EC)

Provides 75 ohm system impedance.

Step attenuator (Option 1E1)

Adds a built-in 60 dB step attenuator to transmission/reflection (ET) models to extend the outputpower range to –60 dBm. The attenuator is standard in

S-parameter (ES) models.

Fault location and structural return loss

(Option 100)

For fully characterizing cable performance and antennafeedline systems, this option provides both fault-location and structural-return-loss capability. Fault-location measurements help identify where cable or system faults, such as bends, shorts, or corroded or damaged connectors, occur. In addition to displaying faults in terms of distance into the cable or feedline, the magnitude of the fault is also displayed.

Structural return loss is a special case of return loss

(reflection) measurements, optimized for measuring periodic reflections of small magnitude. These periodic reflections can occur from physical damage to the cable caused by rough handling, or from minor imperfections imparted during the manufacturing process. Structural return loss problems occur when these periodic reflections sum at half-wavelength intervals, causing high signal reflection (and low transmission) at the corresponding frequency.

Transport case and fault location and structural return loss (Option 101)

Combines a rugged transport and operation case

(part number 08712-60059) with Option 100 for field measurements of fault location and structural return loss.
