E6380A AMPS/CDMA

Base Station Test Set

The E6380A Base Station Test

Set offers, in one box, all the

CDMA test capability you need

for measuring transmitter per-

formance, including the wave-

form quality measurement rho

(r) and code domain analysis

(the way to measure power, tim-

ing, and phase in each code chan-

nel). The test set includes CDMA

and AWGN sources which make

this solution receiver-test ready.

• Signal quality measurements

- rho (r)

- Estimated rho (r)

- Time offset

- Frequency error

- Carrier feedthrough

• Code domain measurements

- Code domain power (in watts or dBm)

- Code domain timing

- Code domain phase

• Average power

• Channel power

• 30 kHz adjacent channel power

• Error vector magnitude (EVM)

• Reverse channel source with

data buffer for RX testing

Automated test software

for fast, repeatable results

For the easiest, most accurate,

repeatable measurement re-

sults, you can automate the con-

trol and operation of your test

set using Agilent base station

automated test software.

Software is typically loaded into

the test set in less than twenty

seconds through the instru-

ment’s PCMCIA card slot. Tests

run automatically, and the user

is prompted to change connec-

tions or cables when necessary.

Manufacturer-specific soft-

ware packages optimize

your test set for a particular

base station’s architecture

and test procedures. The

software can be customized

to meet your individual test

needs, and measurement

results can be stored on

PCMCIA cards or on a PC

hard drive.

• AWGN (built-in calibrated

levels)

• Support for CDMA reference

clocks and triggers

• PN offset search

Manufacturer-specific

software packages

optimize your test set

for each base station’s

architecture and test

procedures

E6380A Option 200

IS-2000 1XRTT

Agilent Technologies now provides

E6380A customers with an up-

grade path to IS-2000. Option 200

for the E6380A provides wireless

network operators a way to test

the performance of their IS-2000

1XRTT systems.

New measurements

include the following:

• Power display for 128 code

channels and supplemental

channels in bit reverse order

• Noise power display for each code

• Total power and code channel

width (number of supplemental

channels)

• Complex power function that

displays power in 128 I and Q

code channels prior to short

code spreading

• IQ constellation diagram

indicating decision points

for one or more symbols

• Estimated rho (r) for IS-2000

1XRTT signals
