Migration examples
When migrating from an 8510/8530 to a PNA Series 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 ana-
lyzer does not exceed –27 dBm by placing attenuators between the 85309B and the
H11 inputs. Review section “Option H11 – IF access” earlier in this document for more
detailed information.
The internal source of the PNA and PNA-X improves the measurement speed over an
external source, however, the internal source is not always feasible to use.

8510/8530 was fixed, so sensitivity can be changed by adjusting the IF BW setting on
the PNA Series.
For fastest remote control of the PNA and PNA-X, 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 or PNA-X 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.

GPS receivers to supply the 10 MHz reference
may be used.
