The Agilent Technologies 8924E CDMA mobile station
test set provides the key set of measurements to verify
the performance of dual-mode CDMA mobile phones
operating from 500 to 1000 MHz. With the Agilent
Technologies 83236B PCS Interface, the 8924E additionally offers CDMA mobile testing from 1700 to 2000 MHz.
Acting as a calibrated, high performance CDMA base station, the 8924E verifies not only the parametric characteristics of CDMA phones, but also the functional
aspects of phone performance.
The 8924E’s full AMPS, NAMPS, EAMPS, TACS, NTACS,
ETACS and JTACS test capability saves you space, cost,
and training expenses by allowing you to make both analog and CDMA digital measurements with the same
instrument.
For complete, call processing verification, the 8924E
supports both mobile and base station initiated call connect and disconnect. Once a phone call is established,
verifying the overall functionality of a CDMA mobile is
simple using the 8924E’s voice echo mode. For testing a
variety of protocol formats, the 8924E offers six user
selectable protocol stacks: IS-95, IS-95A, TSB-74, J-STD008, ARIB T53, and KOREAN PCS. The 8924E also supports a number of service options, including 9600 BPS
and 14,400 BPS traffic channel configurations.

High Accuracy CDMA Source for CDMA Receiver
Test
The 8924E provides active cell site emulation by supporting the following CDMA channels: pilot, sync, paging, traffic, and orthogonal channel noise source (OCNS).
An additive white Gaussian noise (AWGN) source is also
included to provide the interference generated by adjacent cells in a working CDMA network. The 8924E measures receiver frame-error-rate (FER) at all four date
rates used in the CDMA system: full, half, quarter, and
one-eighth. Confidence limit technology is used to
reduce receiver test time to an absolute minimum.
CDMA Transmitter Measurements
The 8924E provides an average power measurement
based on new DSP technology. A DSP based channel
power measurement enables the 8924E to achieve accurate low level CDMA power measurements. Access probe
power measurements are also available. The 8924E
measures transmitted waveform quality by using the
IS-98A/J-STD-018 recommended correlated power
method, also known as the rho (ρ) measurement. In
addition, the rho measurement reports the frequency
error, modulation phase and amplitude error, and the
carrier feedthrough.
Handoff Verification
To speed testing, the 8924E supports hard hand-offs
between RF channels. CDMA to analog hand-offs from
both cellular and PCS bands are also supported.
Authentication and Short Message Service Support
The 8924E provides the necessary features for testing a
CDMA mobile station’s ability to perform call processing
functions with authentication for Korea and the United
States. Also, the 8924E supports mobile terminated SMS.
Automated Software
The Agilent Technologies E8290A PoST (point of service
test) software makes the 8924E an automated CDMA test
solution. The E8290A quickly provides accurate phone
performance and quality data at the point of sale. This
PC-based solution is very easy to use, reduces churn,
reduces no trouble found (NTF), and improves customer
care.
The Agilent Technologies 83217A CDMA dual-mode
mobile station test software can also be used to automate CDMA and analog mobile phone measurements.
The 83217A solution does not require a PC. Rather, automatic tests can be completely set up using the front
panel of the 8924E. Options are available to meet your
test needs for CDMA, AMPS, NAMPS, JTACS, NTACS,
U.S. PCS, and Korean PCS phones.
Specifications describe the instrument’s warranted performance
and apply after a 30 minute warm-up. These specifications are
valid over the 8924E’s entire operating environmental range
unless otherwise noted.
Supplemental Characteristics (shown in italics) are intended to
provide additional information, useful in applying the instrument
