10 dB steps. A buffered output drives 50 Ω load impedances up to 5 V. The PDA100A2 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
Power the PDA100A2 on using power switch located on top side of unit. Caution! The active detector area in the PDA100A2 is offset from the front of the housing. When using fiber adapters, make sure that the fiber ferrule does not crash into the detector. -

> 5 kΩ) and 5 V for 50 Ω loads. Adjust the gain so that the measured signal Load level out of the PDA100A2 is below 10 V (5 V with a 50 Ω load) to avoid saturation. For low terminating resistors, <5 kΩ or 1% error, an additional factor needs to be considered. -
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
±12 mV (Max) ±12 mV (Max) The PDA100A2 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 Si Switchable Gain Detector Chapter 6: Specifications Electrical Specifications Detector Active Area Ø9.8 mm (75.4 mm λ Wavelength Range 320 to 1100 nm λ Peak Wavelength 960 nm (Typ.)
