Santec PEM-340 - Analog Output

Polarization Extinction Ratio Meter PEM-340
8-7
8-8. Analog Output
The analog interface (AIF) located on the rear panel of the PEM-340 enables the measured
signals to be monitored as analogue voltages. The voltages mirror directly the values displayed
on the front panel with the same refresh rate. The connector is a Hirose Electric HR10-7R-
6S. The corresponding plug is a Hirose Electric type HR10-7P-6P. The pin assignment for the
connector is detailed below.
