The Agilent Technologies E8285A
CDMA mobile station test set provides
CDMA mobile phone manufacturers
with increased measurement speed,
improved accuracy, and flexibility to
increase test throughput and product
quality. Built from the industry-standard
Agilent Technologies 8924C, the
E8285A offers proven performance and
reliability with increased capabilities
for manufacturing all current types of
TIA/EIA-95-A based CDMA mobile
phones in a one-box test set. The
E8285A additionally provides flexible
base station emulation and a large set
of capabilities which enable CDMA
mobile phone designers to produce
high quality designs in less time.

With the addition of the Agilent
Technologies 83217A dual-mode mobile
station test software, the E8285A
becomes an easy-to-use automated
test system capable of quickly testing
dual-mode CDMA mobile phones for
incoming inspection, customer-return
testing, and depot-level repair
applications.

One-Button Call Processing

With the press of a single button, the
E8285A automatically handles the
complex, over-the-air call processing
required to make a CDMA or analog
phone call. For call processing
verification, the E8285A supports both
mobile- and base-station initiated call
connect and disconnect. Once a call is
established, verifying the overall
functionality of a CDMA mobile is easy,
fast, and accurate using the E8285A’s
extensive set of functional and
parametric test capabilities. The
E8285A offers eight user-selectable
protocol stacks: IS-95, IS-95A, TSB-74,
ARIB-T53, Korean PCS, J-STD-008, and
TIA/EIA-95B, as well as Multi-Mode,
which allows handoffs between the
CDMA PCS and CDMA cellular bands.

the measured power or less than –20 dBm at the
E8285A’s DUPLEX OUT.

Input Frequency Range:

800 MHz to 1000 MHz,
1700 MHz to 2000 MHz.

Input Connector: RF IN/OUT

Measurement Bandwidth: Provides an accurate

measure of the total power for all present signals
within ±2 MHz of the specified operating frequency.
If other signals are present outside of this frequency
range, reduced measurement accuracy will result.

Maximum Input Level: +34 dBm (2.5 watts continuous)

Measurement Range: –10 dBm to +34 dBm, usable to

–20 dBm with degraded accuracy.

Accuracy: –10 dBm to +30 dBm

Measurement Method: Reports the overall average

CDMA Tuned Channel and Access Probe
Power Measurements

Input Frequency Range:

800 MHz to 1000 MHz,

1700 MHz to 2000 MHz.

Input Connector: RF IN/OUT, ANT IN.

Measurement Bandwidth: Measures the total power

in a 1.23 MHz bandwidth centered on the active
reverse channel center frequency.

Maximum Input Level:
RF IN/OUT: +34 dBm (2.5 watts continuous)

ANT IN: +15 dBm

Measurement Range:

RF IN/OUT: –50 dBm to +30 dBm, usable to

<–55 dBm with degraded accuracy

Measurement Accuracy:

Relative Mode: RF IN/OUT and ANT IN

(uncalibrated against average power relative to
–10 dBm):

0 to –10 dB relative level: ±0.1 dB
–10 to –20 dB relative level: ±0.2 dB
–20 to –40 dB relative level: ±0.5 dB

Calibrated Mode:

RF IN/OUT (Calibrated against average power):

Typically ±1.2 dB at ±10 °C from the
calibration temperature.

Temperature Drift: Typically 0.2 dB per 10 °C

temperature change, 800 MHz to 1000 MHz.

Typically 0.4 dB per 10 °C temperature change,
1700 MHz to 2000 MHz.

Measurement Period: Measures power in a 1.23 MHz
bandwidth over 1/2 of a CDMA frame (8 power
control groups) in full, half, quarter, or one-eighth
rate modes.

Calibrate: Calibrates the channel power measure­ment over the entire operating frequency range of
the currently selected RF channel standard.

Alternate Channel Standard: Allows the selection
of a second channel standard, all bands, PCS band or
cellular band to be calibrated when the channel power
calibration is performed. This allows switching
between two or more standards without having to
re-calibrate after each RF channel standard change.

Un-Calibrated Flag: Displays “Uncal” under the
channel power measurement whenever the unit
detects that the channel power calibration has not
been run for the currently set RF channel standard or
when the temperature has drifted by more than ±10 °C
from temperature at last calibration.

Access Probe Power Trigger Level: Automatically
triggers when input level increases to greater than

-

55 dBm.

parameters.

FER Reported Parameters: Measured FER, Number
of errors, number of frames tested, and one of the
following: passed confidence limit, failed confidence
limit, or max. frames (test indeterminate).

Conditions for Terminating FER Test (with

confidence limits on):

Max Frames: Maximum number of frames to test

completed—indicative of an indeterminate test

result.

Failed: Measured FER failed the specified FER

limit with specified confidence.

Passed: Measured FER passed the specified FER

limit with specified confidence.

FER Measurement Indicators: Testing, Passed,
Failed, and Max. Frames. All indicators are available
over GPIB.

One Button Min/Max Power Measurement

Measurement Method: Automatically sets the
E8285A to the nominal TIA/EIA-98-B/ANSI
J-STD-018 test conditions for the minimum power
measurement and then maximum power measure­ment. Restores the E8285A to the instrument state
active before the measurement was initiated.

Measurement Output: Maximum TX power and
