Internal Bit-Error-Rate Analyzer, Option Un7 - Agilent Technologies E4400B Configuration Manual

Internal bit-error-rate
analyzer, Option UN7
Option UN7 simplifies hardware
configurations and measurement
procedures. Minimize benchtop
equipment and expense with the
optional built-in BER analysis capa-
bilities of the ESG-D series signal
generators. The straight-forward
user interface makes it easy to
quickly setup measurements.
Description
Option UN7 offers generic analysis
capabilities for demodulated data
sequences. It is provided on a user-
installable card that can be added to
the B version of any existing ESG or
any new instrument.
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 with bit error rates
< 0.001 ppm.
Automatic check of data and clock validity
Avoid erroneous measurements
caused by invalid data or clock
inputs.
The BER analyzer will automatically
indicate when either the data and/or
clock signals are lost or not valid.
Standalone BERT capabilities
Test any PN9 or PN15 sequence,
whether internally or externally
generated.
Use Option UN7 to measure BER of
externally generated PN sequences.
The ESG-D with the BER analysis
option will automatically synchronize
on PN9 or PN15 sequences clocked
in at the appropriate data rate.
Continuously updated BERT 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.
Bit-error-rate 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 Ω 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.
