Setup
CAUTION
Mount the unit in a position that does not block airflow to the fan and heat sink.

1. Unpack the detector head.
2. (
Optional
) Install a Thorlabs Ø1/2" diameter TR Post (n
ot included
) into one of the 8-32 tapped holes (M4
in -EC version) located on the bottom and side of the head, and mount into a optical post holder (sold
separately).
3. Connect the 4-pin power supply plug into the power receptacle on the PDA10PT.
4. Plug the power supply into a 50 - 60 Hz, 100 - 240 VAC outlet.
5. Attach a 50 Ω BNC cable to the output of the PDA. When running cable lengths longer than 12", we
recommend terminating the opposite end of the coax with a 50 Ω resistor (Thorlabs T4119 BNC in-line
terminator) for maximum performance. Connect the remaining end to a measurement device such as an
oscilloscope or high-speed DAQ card.
CAUTION
Many high speed oscilloscopes have input impedances of 50
Ω. In this case, do not install a 50 Ω
terminator. The combined loads will equal 25
Ω which could allow ~135 mA of output current. This
will damage the output driver of the PDA10PT.
