Programming using IBASIC
As a standard feature, all HP 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 HP-IB, 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).
