Migration examples

When migrating from an 8510/8530 to a PNA network analyzer, it is important to recognize the differences in power, speed and sensitivity between the analyzers.

In remote mixing configurations, using Option H11, the damage level of the PNA is much lower than the 8510/8530. You must assure that the power going into the analyzer does not exceed –27 dBm by placing attenuators between the 85309A and the H11 inputs.

Review section “Option H11 – IF access” earlier in this document for more detailed information.

The internal source of the PNA improves the measurement speed over an external source, however, the internal source is not always feasible to use.

The IF BW setting on the PNA and PNA-L is adjustable, the IF BW of the 8510/8530 was fixed, so sensitivity can be changed by adjusting the IF BW setting on the PNA and PNA-L.

Software will not port directly from 8510/8530 code to PNA code. For fastest remote control of the PNA, the use of COM programming is recommended. See “Measurement

Automation” later in this document. Contact your Agilent Applications Engineer for additional assistance with programming.

The following two examples show conceptually how to migrate from an 8510/8530 to a

PNA based antenna system. Since every system is unique, it is not feasible to show every modification necessary for the conversion. Refer to “Antenna measurement design considerations” earlier in this document for additional guidance, or contact your Agilent applications engineer for assistance.
