Atec Wavetek-3600D - Manual (Page 2)

Upgrading the 3600D is easy. With
the new CDMA module, technicians
can perform call processing, trans-
mitter tests, and receiver tests. Built-
in AMPS and NAMPS protocols are
standard, while PCS coverage is
provided with an optional FEX
module. Based upon requirements of
IS-95A and J-STD-008, the 3600D’s
extensive call processing capabilities
include registration, authentication,
and softer and hard handoffs.
In the critical area of power
control, closed loop and open loop
power control are supported. Speech
coding can use pre-recorded, loop-
back, or an optional 8K/13K Vocoder
to check voice quality.
CDMA Capabilities for
Cellular and PCS
The 3600D’s signal generator
provides pilot, sync, paging, and
selectable traffic channels. An
Additive White Gaussian Noise
source with 30 dB troubleshooting
range allows real world receiver
testing. The constellation display
shows the symmetry of the mod-
ulator and checks for skew and origin
offset. Residual
ρ
is better than 0.97
for confidence in receiver testing.
CDMA and
TDMA Formats
Testing digital phones is simple
and effective with the 3600D.
Authentication, Call Waiting,
SMS, and Calling Number ID
test capabilities allow phone
features to be thoroughly check-
ed. The standard VSELP Codec
allows technicians to check voice
quality end-to-end, while the
new ACELP Voice Codec option
TDMA Testing, IS-136,
and Voice Codecs
Highly accurate, the transmitter
analyzer provides power measure-
ments of ±0.65 dB +0.003 dB/dB
(below +40 dBm) over temperature.
The high
ρ
accuracy is ±0.003 is ideal
for phone troubleshooting non-
linearity or amplifier defects.
