General Information
1-1 SCOPE OF MANUAL This manual provides general and service information for the Model
360B Vector Network Analyzer (VNA) system (Figure 1-1). (Through-
out this manual, the terms 360B VNA and 360B will be used inter-
changeably to refer to the system.) Manual organization is shown in
the narrative Table of Contents that precedes this chapter. The infor-
mation in this manual provides for fault isolation to the assembly level
for system instruments. Covered instruments consist of network ana-
lyzer, signal (frequency) source, test sets, and 360ACM used with the
3635B mm-wave test set.
1-2 INTRODUCTION This chapter provides general information about the 360B VNA sys-
tem. It also provides replaceable-assembly information and a listing of
recommended test equipment for servicing 360B VNA system instru-
ments.
1-3 IDENTIFICATION NUMBER All WILTRON instruments are assigned a unique six-digit ID number,
such as “701001.” This number is affixed to a decal on the rear panel of
each unit. In any correspondence with either WILTRON Customer
Service or your Anritsu/Wiltron Service Center, please use this number.
NOTE
The system operating software is keyed to the analyzer
identification number. For systems having certain option
installed, the operating-system will only load on the serial-
numbered 360B for which the software is identified.
1-4 RELATED MANUALS Manuals related to the operation and maintenance of the 360B VNA
system are listed in Table 1-1. This table also lists the 360B VNA
optional equipment manuals.
