Features RF Network Analyzers
1-82 Service Guide
SICL LAN: SICL LAN is a LAN protocol using the Standard Instrument Control
Library (SICL). It provides control of your analyzer over the LAN using a variety of
computing platforms, I/O interfaces, and operating systems. With SICL LAN, a remote
analyzer can be controlled over the LAN with the same methods used for a local
analyzer connected directly to the controller with GPIB. SICL LAN can also be used
with Windows 95/98/NT, or HP-UX.
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 address, a
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 using IBASIC
As a standard feature, all 8712ET/ES and 8714ET/ES network 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
• barcode-reading capability
• 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 system directivity, source match, load match, frequency response, and crosstalk.
The analyzer features 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 special 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: response, response
and isolation, enhanced response, and two-port (two-port calibration requires an ES
model).
