HP 10017A, HP 10018A, HP 10080A, HP 10081A

Refer to \Adjusting the Probe" in Chapter 3 how to adjust the probe which is connected to a

network analyzer or a spectrum analyzer.

1-2 General Information

Serial Number

Hewlett-Packard uses a two-part, nine character serial number which is stamped on the serial

number plate (see Figure 1-1 ) attached to the instrument's rear panel. The rst four digits

and a letter are the prex, and the last ve digits are the sux of the serial number. The

letter in the serial number identies the country where the instrument was manufactured.

The prex is same for all identical instruments; it changes only when a change is made to the

instrument. The sux, however, is assigned sequentially and is dierent for each instrument.

This operation note applies to instruments with the serial number prexes listed under SERIAL

NUMBERS on the title page.

Figure 1-1. Serial Number Plate

Units manufactured after this operation note was printed may have a serial number prex that

is not listed on the title page. An unlisted serial number prex indicates that the instrument

may be dierent from those described in this operation note

instruments may be accompanied by a yellow Manual Supplement page or have a dierent

manual part number. This supplement contains \Change Information" explaining how to adapt

this operation note to the newer instruments.

In addition to change information, the supplement may contain information for correcting

errors (Errata) in the previous operation notes.To keep this manual as current and accurate as

possible, Hewlett-Packard recommends that you periodically request the latest Manual Changes

supplements. The supplement for this operation note is identied by the Print Date and HP

Part No., both of which appear on the operation note's title page.

For information concerning the serial number prex not listed on the title page or in the

Manual Change supplements, contact your nearest Hewlett-Packard oce.
