RF Network Analyzers Features
Service Guide 1-81
Data Hardcopy
Hardcopy prints can be made using PCL and PCL5 printers (such as HP DeskJet or
LaserJet series of printers), or Epson-compatible graphics printers. Single color and
multicolored formats are supported. Hardcopy plots can be automatically produced with
HP-GL-compatible plotters such as the HP 7475A, or with printers that support HP-GL.
The analyzer provides Centronics (parallel), RS-232C, GPIB, and LAN interfaces.
Automation
Controlling via GPIB
Interface: 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 a standard feature.
SCPI: The analyzer can be controlled by sending Standard Commands for
Programmable Instruments (SCPI) commands 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 Java applets. 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: Instrument state and data files can be transferred via file-transfer protocol (ftp).
An internal dynamic data disk, which is an ftp directory, 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 hypertext transfer protocol (http) and the 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 with http via a LAN connection.
