CAUTION
The inputs of the M8046A module are sensitive to static electricity.
Therefore, take necessary anti-static precautions, such as wearing a
grounded wrist strap, to minimize the possibility of electrostatic damage.
Component
Description
Data In and /Data In
Differential data inputs (3.5 mm, female)
Clk In
Clock input to sample the incoming data. Full/half and quarter-rate clock.
Single ended. CTRL IN can be used as sequence trigger or pattern capture
event.
Sync In
This input is used to clock the analyzer from the pattern generator’s M8045A
system clock via the sync output A/B (requires cable M8051A-801). Not needed
if external clock is used.
This input is only available for M8046A modules with a serial number below
DExxxx01000.
Ctrl Out A
Outputs a pulse in case of an error. Generates a pulse or static high/low if used
from sequencer.
