Agilent Technologies 8935 series e6380a Manuale Utente

General Information

The following conventions are used throughout this manual to help 
clarify instructions and reduce unnecessary text:

• “Test Set” refers to the Agilent 8935 CDMA Cellular/PCS Base 

Station Test Set.

• Test Set keys are indicated like this: 

• Test Set screen information, such as a measurement result or an 

error message, is shown like this: 

TX Channel Power -1.3 dBm

HP-IB and GPIB are one and the same.

•

 familiarizes you with the 

front panel controls. It introduces the different types of control fields 
that are used to make measurements

•

 provides general 

information about how to change measurement screens and change 
control field settings. This chapter also provides some utility 
procedures: calibrating channel power, setting a reference, setting 
measurement limits, setting a generator/analyzer offset, averaging 
measurements, saving and recalling setups, and using USER keys.

•

introduces the RFTOOLS program. This program automates some 
measurements: cable fault location, swept return loss, swept and 
discrete insertion loss, spectrum analyzer self-calibration. The 
program also includes utilities for printing and data collection.

Basic operation of the built-in signal strength meter, spectrum 
analyzer, oscilloscope, and code domain analyzer is also included in 
this chapter.

•

 explains the measurements that can be made from these 

screens and the fields that control the measurement’s parameters.

CDMA measurements include average power measurements, 
channel power measurements, rho measurements (including 
frequency error, time offset, and carrier feedthrough), EVM 
measurements (including phase error and magnitude error), and 
code domain measurements (both IS-95 and IS-2000 standards).
