Page 6: Chapter 2 Safety
(versus being listed in this section). DANGER! The Thorlabs Spectrum Analyzer Controller, SA201, must be powered off, unplugged from the AC input source, and disconnected from any piezo elements prior to replacing the fuse or removal of the cover. Failure to do so may cause SERIOUS INJURY to the user, since high voltages exist within the unit. -

Page 10: Detector Gain Adjustment
Spectrum Analyzer Controller Chapter 4: Description 4.1. 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 11: Amplitude Control
Spectrum Analyzer Controller Chapter 4: Description 4.7. Amplitude Control The amplitude control allows the user to adjust the ramp amplitude from 1 to 30 V peak to peak using a 10-turn trim pot. Note, the ramp signal is added to the DC offset. -
Page 12: Trigger Output Bnc
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. -
Page 13: Ground Plug
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 photodetectors; however it is possible to operate user supplied photodetectors. To do so, the BNC center contact must be connected to the photodetector cathode and the BNC shell must be connected to the photodiode anode (unbiased operation). -
Page 14: Pd Amplifier Output Bnc
Spectrum Analyzer Controller Chapter 4: Description NOTE The PDAVJ5 that is recommended for use along with the SA200-30C should not be connected to this input. Connecting to the amplifier will cause damage to the instrument. 4.14. PD Amplifier Output BNC This BNC is the amplifier output and may be connected directly to an oscilloscope to view the cavity spectrum. -
Page 15: Chapter 5 Operation
Spectrum Analyzer Controller Chapter 5: Operation Chapter 5 Operation 5.1. PD Blanking Circuit The detector amplifier includes a blanking circuit, which blocks any photodetector response during the falling edge of the saw tooth waveform. This is very useful when triggering on the photodiode spectral response, because unwanted signals while the cavity resets will be removed. -
Page 16: 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. -
