Introduction

•
Sync Out
- The four Sync Outputs can be used to synchronize the
M8132A with one or more M8121A AWG modules in order to achieve
deterministic latency between the M8132A and the M8121A AWG.
Sync Out of the M8132A is connected to the Sync In of the M8121A
AWG module.
•
Ref Clk In
- The Reference Clock Input can be used to synchronize to an
external clock.
•
Ref Clk Out
- The Reference Clock Output can be used to synchronize a
DUT to the M8132A.
•
FPGA Config
- The FPGA Configuration connector can be used to load
and debug the open FPGA externally.
•
Control In/Out
- The Control Input/Output offers a 10-bit parallel
interface. Bit 0 to 4 is configured as input, bit 5 to 9 is configured as
output. The Control In/Out is connected with the sandbox ports of the
FPGAs.
LEDs
The M8132A front panel include the following LEDs:
• Status LEDs
The “Fail” and “Access” LEDs are available at the front panel to indicate
the status of the M8132A module:
•
The green ‘Access’ LED indicates that the controlling PC exchanges
data with the M8132A module.
•
The red ‘Fail’ LED has following functionality:
•
It is ‘ON’ for about 30 seconds after powering the AXIe chassis.
•
After about 30 seconds the LED is switched ‘OFF’. If an external
PC is used to control the AXIe chassis, this PC can be powered
after this LED has switched OFF.
•
During normal operation of the module this LED is ‘OFF’. In
case of an error condition such as e.g. a self-test error, the LED
is switch ‘ON’.
•
In case the output relay has shut-off because of an external
overload condition, this LED flashes.
