The
Firmware Revision
screen displays identifying information for the DXL5000. Have this
information ready for customer service as described in
3.2.6
Status–Monitor Monitor Mod (Transmitter) and Demod (Receiver)
The
Monitor Mod and Monitor Demod
screens displays the following information.
System Software
SCM PC FPGA (single carrier modulator PC field programmable gate array)
SCM PC uP (single carrier modulator PC microprocessor)
SCD PC FPGA (single carrier demodulator PC field programmable gate array)
SCD PC uP (single carrier demodulator PC microprocessor)
Radio Type
Symbol Rate
Displays 3.0 to 33 mega-symbols per second (Msps).
Modulation
Displays the modulation type (
QPSK
,
16QAM
,
32QAM
,
64QAM
).
Percent
Utilization
Displays a capacity value based on calculations derived from the
Symbol Rate
,
Modulation
, and the combined
Data Rates
for each
Core Channel
. If this
number is over 100%, you should adjust the values described in
Determining Optimal System Utilization
Core Channel
1, 2, 3, and 4
Displays one of the following the data inputs or outputs and its speed at
megabits per second (Mbps).
ASI BNC-1
ASI BNC-2

Invert
Spectrum
Displays
On
or
Off
for the Invert Spectrum.
PRBS
Displays
On
or
Off
(default) for the Pseudo Random Bit Sequence (PRBS).
PRBS is used for link testing purposes; turning PRBS
On
causes a data service
override.
The following fields apply only to the receiver.
SNR
Displays the number of dB for the signal-to-noise ratio (SNR) that measures the
signal strength and signal quality.
EVM
Displays a percentage of the error vector magnitude (EVM) that measures the
performance of the radio.
BER
Active only when the transmitter has PRBS
On
, BER displays the bit error ratio
(BER), which is the percentage of bits that have errors relative to the total
number of bits in the signal, and indicates how often a packet or data unit has to
be retransmitted because of an error. You can click
Reset BER
to start a new
ratio.
