Problem with 2-port N5261A test set

If there is a problem using an N5261A 2-port test set with PNA firmware A.09.80.20, the problem is most likely caused by the firmware. Upgrade the firmware to A.09.90.08 or later and the problem should be fixed.

Operational Verification for mmWave Systems

Operational verification procedures are supported for various mmWave systems. These procedures are typically performed at initial system installation and whenever confirmation of proper system performance is required.

Operational verification procedures for mmWave systems do not use fixed pass/fail limits. Various performance characteristics are measured. The user then compares these measurements to measurements made previously on the system or to values from known standards (such as those in a verification kit). Pass/fail determination requires engineering judgment.

Annual system calibration is not supported on mmWave systems. Most mmWave systems do not have "hard" specifications, so there is no requirement for an annual calibration. An annual calibration may be performed stand-alone on the network analyzer that is part of the system.

Of course, a "user" calibration is supported for all mmWave systems. This is a calibration performed with a calibration kit prior to making measurements with a system.

The sections below provide links to detailed operational verification information for various types of mmWave systems.

N5251A 110GHz Swept Systems

See Chapter 6 of N5251A Installation and Service Guide (N5251-90001).

Systems based on OML heads

See the System Operation Verification section of N5261A/62A User's and Service Guide (N5262-90001). These instructions assume the OML head is used with an N5261A/62A controller. If a controller is not used (i.e. direct connect), then modify the instructions accordingly.

Systems based on VDI heads

See Operational Verification for VDI Heads.
