Key Features - Agilent Technologies E4400B Configuration Manual

Baseband BER testing
Option 300 includes baseband BER
testing (cannot be ordered separate-
ly). BER simplifies hardware
configurations and measurement
procedures. Minimize benchtop
equipment and expense with the
optional built-in BER analysis
capabilities of the ESG-D series
signal generators. The straight-
forward user interface makes it
easy to quickly setup measurements.
Description
BER offers generic analysis capabili-
ties for demodulated data sequences.

Key features

Data rates up to 10 Mbps
Choose the data rate that meets your test
requirements.
Use the 2 Mbps data rate to test
BER of common wireless communi-
cations systems, subsystems and
components. Offering continuous
update of total bits measured, bit
count and BER, the 2 Mbps mode
provides constant feedback on
measurement status. Select the
10 Mbps mode for higher data rate
digital communications applications.
Pass/fail indicators
Quickly and consistently determine
pass/fail conditions.
Use the 2 Mbps mode of operation
to continuously display pass or fail
status according to a user-defined
maximum BER limit.
Long 4 Gbit measurement capability
Test BER of continuously repeating
PN sequences.
With the capability of testing bit
sequences up to 4 Gbits long, the
ESG-D series can measure a PN15
sequence that has been repeated
over 100,000 times. In addition,
this capability allows measurement
of data sequences
Automatic check of data and clock validity
Avoid erroneous measurements
caused by invalid data or clock
inputs.
The BER tester will automatically
indicate when either the data and/or
clock signals are lost or not valid.

Standalone BER testing capabilities
Test any PN9 or PN15 sequence,
whether internally or externally
generated.
Use the baseband BER tester to mea-
sure BER of externally generated PN
sequences. The ESG-D with the BER
tester will automatically synchronize
on PN9 or PN15 sequences clocked
in at the appropriate data rate.
Continuously updated BER test results
Instantly determine the current
status of the bit error rate test.
Efficiently measure BER with a
continuous update of total bits
counted, total bit errors detected
and the current bit error rate ratio.
EDGE base station bit error rate test.
Baseband BER tester user interface.
Automatic measurement re-synchronization
Increase measurement productivity
in noisy test environments.
Noisy test conditions can cause
loss of synchronization during a
measurement, thus generating
incorrect results. A user-defined
re-synchronization limit is available
to reset all counters and restart the
measurement automatically when
synchronization is lost.
TTL or 75 impedance
Select the impedance that meets
your measurement needs.
Set the CLOCK IN, DATA IN and
CLOCK GATE IN to either TTL
compatible or 75 ohm to match (or
replace) other test equipment.
