(1) Press [INPUT/FILTERS] and then set the input mode to <I> and <Amplitude: 1M>. Other settings remain the
default.
(2) Press [REF/PHASE] and then set <Ref. Source: External> and <Type: TTL>.
(3) Press [GAIN/TC] and then set <Sensitivity: 1μA> which can be adjusted in measurement, <Reserve: Normal>,
<TC: 300ms> and <Roll off: 12dB/oct>. Finally, turn off the SYNC filter.
(4) Press [OUTPUT/OFFSET] and then set <CH1>, <Source: R> and <Speed: Fast>.
3. Build up the spectral measurement platform.
Use a BNC cable to connect the output of the photoelectric detector and the IN+ input of the SE1022D.
Use a BNC cable to connect the OUTPUT of the optical chopper and the REF IN of the SE1022D.
Use a BNC cable to connect the data collection platform and the CH1 OUT of the SE1022D. The sketch is shown
