Page 4: Chapter 2 Description
10 dB steps. A buffered output drives 50 Ω load impedances up to 5 V. The PDA36A2 housing includes a removable threaded coupler (SM1T1) and retainer ring (SM1RR) that is compatible with any number of Thorlabs 1"... -
Page 5: Chapter 3 Setup
Attach a 50 Ω coax cable (i.e. RG-58U) 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 p/n T4119) for maximum performance. Connect the remaining end to a measurement device such as an oscilloscope or high speed DAQ card. -

Chapter 4 Operation 4.1. Theory of Operation Thorlabs PDA series are ideal for measuring both pulsed and CW light sources. The PDA36A2 includes a reverse-biased PIN photo diode, mated to a switchable gain transimpedance amplifier, and packaged in a rugged housing. -
Page 7: Bandwidth And Response
The maximum output of the PDA36A2 is 10 V for high impedance loads (i.e. RLoad > 5 kΩ) and 5 V for 50 Ω loads. Adjust the gain so that the measured signal level out of the PDA36A2 is below 10 V (5 V with a 50 Ω load) to avoid saturation. -
Page 8: Chapter 5 Troubleshooting
Si Switchable Gain Detector Chapter 5: Troubleshooting Chapter 5 Troubleshooting Problem Suggested Solutions Verify that the power is switched on and all connections are secure. Verify the proper terminating resistor is installed if using a Voltage measurement device. There is no signal response. Verify that the optical signal wavelength is within the specified wavelength range. -
Page 9: Chapter 6 Specifications
±10 mV (Max) ±12 mV (Max) The PDA36A2 has a 50 Ω series terminator resistor (i.e. in series with amplifier output). This forms a voltage divider with any load impedance (e.g. 50 Ω load divides signal in half). Tested at 650 nm wavelength. For NIR wavelengths, the rise time of the photodiode element will become slower which may limit the effective bandwidth of the amplified detector. - Page 10 Measured from the active area to the start of the threads on the housing body. The detector active area surface is flush with the front of the housing body. Although the power supply is rated for 31 W the PDA36A2 actual usage is <5 W over the full operating range.
