Connector
Description
1
CLOCK
OUTPUT
Clock Output connectors. Use the differential connectors to output a clock signal from the
Pattern Generator. (Amplitude range: 250 mV to 2 V
p-p
).
2
DATA
OUTPUT
Data Output connectors. Use the differential connectors to output data from the Pattern
Generator. (Amplitude range: 250 mV to 2 V
p-p
).
3
EXT CLOCK
External clock input connector. Use this input to connect an external clock source to the
BERTScope analzyer; (maximum input amplitude of +10 dBm or 2 V
p-p
).
HF JITTER
High-frequency jitter insertion input connector. Use this connector to add external
high-frequency jitter (DC to 1 GHz) to the instrument with up to 0.5% UI. Apply signals
up to 16 dBm (4 V
p-p
) if needed.
This connector is available on the rear panel of BSA286CL instruments.
4
SUBRATE
CLOCK–
BSA286CL only, Pattern Generator Subrate clock–. Use this connector to provide the –
side of a differential clock.
The signal available at this output connector depend on the settings in the Generator view.
Select SUBRATE to produce a Pattern Generator clock or a submultiple of the clock without
any added jitter (useful for measuring any jitter that was added to the Pattern Generator
output). Select STRESS to produce a version of the Pattern Generator clock including
any added jitter.
5
SUBRATE
CLOCK
Pattern Generator Subrate clock output connector. (See the description above.) For the
BSA286CL instruments, this is the + output of the differential signal. For other BSA versions,
this is a single-ended output.
6
TRIGGER
Pattern Generator trigger output connector. Use this connector to synchronize external
equipment, such as an oscilloscope to the BERTScope analyzer.
