Page 7: Introduction
BNC-ended detector. A typical setup is shown in Figure 1. Figure 1: Typical experimental setup In Figure 2, the Oriel model 75160NF chopper controller sits on top of a Stanford Research Systems (SRS) model SR810 Lock-In Digital Amplifier (LIDA) instrument. The chopper is being driven at 30Hz through the internal frequency generator of the SR810. -
Page 8: Features
3 FEATURES The LIDA-SRS-KIT includes the chopper, chopper control, lock-in amplifier, and readout (gauge or software) used in a typical experimental set-up and connects to any BNC-ended detector. The Stanford Research Systems (SRS) SR810 Lock-In-Digital-Amplifier (LIDA) provides high performance at a reasonable cost and integrates into Oriel’s product line. -
Page 9: Input Channel
3.1.1 Input Channel The SR810 Lock-In Amplifiers have differential inputs with 6 nV/√Hz input noise. The input impedance is 10 MΩ, and minimum full-scale input voltage sensitivity is 2 nV. The input can also be configured for current measurements with selectable current gains of 106 and 108 V/A. A line filter (50 Hz or 60 Hz) and a 2×... -
Page 10: Auto Functions
3.1.6 Auto Functions Auto-functions allow parameters that are frequently adjusted allowing automatic setting by the instrument. Gain, phase, offset and dynamic reserve are each quickly optimized with a single key press. The offset and expand features are useful when examining small fluctuations in a measurement. -
Page 11: Basic System Setup
Detector signal cable with BNC male connector Refer to the TracQ Basic user’s manual for minimum system requirements for the computer. If an Oriel LIDA-compatible detector is utilized, it includes a signal cable and amplifier power cable. 4.3 UNPACKING Remove all items from the shipping containers and verify each item is accounted for. -
Page 12: Choosing A Location
4.4 CHOOSING A LOCATION Choose an installation location where the power requirements can be met for the system. Be sure power is not applied to the system until the setup has been completed. The environment should be that of a typical laboratory atmosphere, without excessive humidity and contaminants in the air. -
Page 13: Computer Connections
4.6 COMPUTER CONNECTIONS Install the driver provided with the GPIB/USB cable from National Instruments. Connect the cable to the GPIB connector on the back of the LIDA and tighten the connections. Plug the USB connector into the computer. If successfully installed, the computer’s Device Manager will display “GPIB USB HS”. -
Page 14: Detector Connections
The “PREAMP” connection on the back of the SR810 is able to provide the power required. It must be utilized with Oriel cable model CBL-70054-LIDA only. The user of any other Oriel cable will damage the amplifier circuit and void the warranty on the detector or stand-alone preamplifier. -

Page 16: Electrical Connections
4.8 ELECTRICAL CONNECTIONS Before powering up the system for the first time, it is suggested to have a qualified electrician verify the wall socket to be used with the LIDA-SRS-KIT meets the requirements for operation as noted. Before making any electrical connections, verify the power switches are in the off position for the lock-in digital amplifier and chopper controller. -
Page 17: Software Configuration
LIDA settings. After the setup is complete, TracQ Basic allows the user to select the desired chopping frequency and operating parameters for the SR810. The software is also able to control various Oriel monochromators. Please refer to the user’s manual included with the software for a list of compatible instruments. -

Page 24: Calibration
7.2 CALIBRATION The LIDA-SRS-KIT with TracQ Basic can display simple voltage or current measurements as well as calibrated readings in radiometric units. Most of Oriel’s LIDA-compatible detectors are available with spectral responsivity data. This type of detector can calculate incident power and it display the readings in real time. -
Page 25: Figure 21: Calibrated Detector File
Prior to taking a detector radiometry data, the wavelength range an wavelength step size (interval) need to be set. Once this information is entered into the software, the detector radiometry scan allows radiant measurement data to be taken over the detector’s calibrated wavelength range. -
Page 26: Quantum Efficiency Measurements
TracQ Basic software allows the LIDA-SRS-KIT and Oriel Monochromators to coordinate their operation in order to obtain QE data. TracQ Basic features built-in QE measurement functionality which allows signal data from the LIDA-SRS-KIT to be displayed in real time. Items needed to build the setup shown in Figure 23: •... -
