Figure 1 SA201 Front Panel Controls Detector Gain Adjustment The SA201 includes a built in photodiode amplifier circuit. This amplifier is designed specifically to operate with the detector provided with the SA200 series Fabry Perot Interferometer, allowing the user to monitor the transmission of the cavity. - Page 7 The SA201 allows the user to select between a saw-tooth and triangular waveform. The saw-tooth waveform is desirable for most applications; however the triangle waveform is useful for cavity alignment. The SA201 will default to the saw-tooth waveform during the system power-up. To change the waveform, simply press the ‘WAVEFORM SEL’...

0.6 µF piezo loads at a ramp rate of 1 ms over the full voltage range. The output current is internally limited to prevent damage to the output drive. Note: the output performance specifications assume a Thorlabs Fabry Perot Interferometer module is connected. -

This input BNC is used to interface the photodetector, provided with the SA200 scanning heads, to the amplifier circuit. The photodiode amplifier is configured to operate with the Thorlabs supplied photo detectors; however it is possible to operate user supplied photo detectors. To do so, the BNC center contact must be connected to the photo detector cathode and the BNC shell must be connected to the photodiode anode (unbiased operation). - Page 10 Spectrum Analyzer Controller results, a 50 Ω load resistor is recommended at the oscilloscope. Note, the amplifier gain will be halved with a 50 Ω load connected. Voltage Selector Switch The voltage selector switch allows the user to select the input line voltage. The factory default setting is 100/115 VAC as shown in figure 4.

This feature may be disabled as described below: IMPORTANT Disconnect the scanning head or any piezo device from the SA201 output. Disconnect the power cord. Do not open the unit if the power cord is connected. -
Page 12: Replacing The Fuse
125 mA Type ’T’ Slow Blow Fuse – The 125 mA fuse is required for 230 V operation only. Thorlabs supplies a 125 mA fuse with all of its SA201 units and must be installed when operating at 230 VAC. -
Page 13: Cleaning
Switch to the appropriate line voltage. Install the appropriate line cord. 1.1.3. Cleaning The SA201 should only be cleaned with a soft cloth and a mild soap detergent or isopropyl alcohol. Do not use a solvent-based cleaner. 6679-D02 Page 12... -
