Full Two-Port Rror-Correction Procedure - HP 8753D Option 011 Service Manual

Consider the following while troubleshooting:
1. All parts of the system, including cables and calibration devices, can contribute to
systematic errors and impact the error terms.
2. Connectors must be clean, gaged, and within speci cation for error term analysis to be
meaningful.
3. Avoid unnecessary bending and exing of the cables following measurement calibration,
minimizing cable instability errors.
4. Use good connection techniques during the measurement calibration. The connector
interface must be repeatable. Refer to the \Principles of Microwave Connector Care"
section in the \Service quipment and Analyzer Options" chapter for information on
connection techniques and on cleaning and gaging connectors.
5. Use error term analysis to troubleshoot minor, subtle performance problems. Refer to the
\Start Troubleshooting Here" chapter if a blatant failure or gross measurement error is
evident.
6. It is often worthwhile to perform the procedure twice (using two distinct measurement
calibrations) to establish the degree of repeatability. If the results do not seem
repeatable, check all connectors and cables.

ote
This is the most accurate error-correction procedure. Since the analyzer takes
both forward and reverse sweeps, this procedure takes more time than the
other correction procedures.
1. Set any measurement parameters that you want for the device measurement: power,
format, number of points, IF bandwidth.
2. To access the measurement correction menus, press:
AL
5
3. Assuming that your calibration kit is the m default, press:
AL KIT 7 MM RETURN
4. To select the correction type, press:
ALIBRATE MENU FULL 2-PORT REFLE TION
5. Connect a shielded open circuit to PORT 1.
