OPERATING INSTRUCTIONS (STAND-ALONE) WHAT’S IN THE BOX

• QCL Instrument
• Power Cable, type appropriate for final location
• Red fuse tray
• Two 0.63 A fuses and two 1.25 A fuses for fuse box on the back panel
• USB Flash Drive, includes all necessary software, instrument documentation, and additional storage space
• Keys for the key switch
• Interlock Replacement Kit (interlocks for QCL D-SUB and Active Interlock BNC) THEORY OF OPERATION The QCL Series low noise drivers are designed expressly to drive quantum cascade lasers, and utilize patented 1 circuitry to deliver ultra-low noise current and still maintain a wide modulation bandwidth. The QCL drivers are controlled current sources; they deliver the current commanded by the setpoint. The current source continually monitors the actual output current, compares it to the setpoint, and adjusts the current if there is a difference between the two signals. As current is driven through the load, there is a voltage drop across the load proportional to the load resistance and current. As the current increases, the voltage drop may increase to the point that it reaches the Compliance Voltage limit of the current source. Once that occurs the current source is no longer able to increase the current driven to the load even if you increase the setpoint. The QCL driver includes features that help protect your laser, and also make the driver more versatile in a wide array of applications. These features are explained in detail in the Operating Instructions.
• The user-adjustable current limit prevents overdriving the laser even if the external modulation signal is above the maximum drive current for the laser.
• Over- and under-voltage protection circuits protect the driver and QCL if the power supply voltages fall outside of the acceptable operating range.
• Over-temperature protection circuits safely shut down the output if the internal temperature of the QCL driver rises to an unsafe level. The fan turns on to manage the internal temperature.
• Output slow-start ramps the current to setpoint over 1.5 msec.
• A mechanical relay shorts the output connections when the output is disabled, and when the QCL driver is powered off. 1Covered by U.S. Patents 6,696,887; 6,867,644 and 7,176,755. Licensed from Battelle Memorial Institute. These instructions are for operating the QCL Laboratory Series instrument. Fuses are provided but not installed. After installing the fuses in the fuse box, be sure to install the fuse box so the correct voltage for your country is showing.

This signal is the sum of the DC setpoint as shown on the screen and the external modulation input. To monitor the analog current level: 1. Connect the Analog output Current Monitor (PIN 8) on the MONITOR D-SUB to an oscilloscope. 2. Connect an Analog Monitor Ground (PIN 7 or PIN 9) to oscilloscope ground. SETPOINT CURRENT MONITOR This is a reference only and can be off by as much as 5% when setpoint is >10% of full scale. To monitor the setpoint current: 1. Measure the voltage on the Analog Setpoint Monitor (PIN 6). 2. Ground for that measurement is the Analog Monitor Ground (PIN 7 or PIN 9). The setpoint monitor and analog current monitor transfer functions depend on the QCL instrument model and are all as follows: QCL500-LAB: 0.1 A / V. QCL1000-LAB: 0.2 A / V. QCL1500-LAB: 0.3 A / V. QCL2000-LAB: 0.4 A / V. The input range is always 0 – 5 V. ALIGNMENT LED DRIVE +5 V, up to 250 mA sourced. To drive an alignment LED, on the MONITOR D-SUB 1. Connect an LED to the Alignment LED +5V (PIN 1). 2. Ground the LED at the Alignment LED Ground (PIN 2). ENABLE STATUS INDICATOR This is a +5 V TTL indicator. If current to the QCL output is enabled, the voltage between PIN 3 and PIN 4 on the MONITORS D-SUB will be low. It will be high if current is disabled. USE THE TRIGGER SIGNAL A trigger signal is provided so that external measurement equipment can be synchronized with laser current. Exactly 10 msec after a remote change in setpoint, a 20 µsec positive going pulse appears on the Trigger BNC plug. To use the Trigger, connect a BNC cable to the TRIGGER BNC output.

PROBLEM POTENTIAL CAUSES SOLUTIONS Noise current is higher than expected. There may be ground loops in the system; some system components may be higher noise than expected; cabling and shielding may be inadequate. Refer to Wavelength Electronics Application Note AN-LD08: “Manage Grounding to Minimize Noise with the QCL Drivers”: http://www.teamwavelength.com/downloads/ notes/an-ld08.pdf Also reference AN-LD09: “Troubleshooting Low Noise Systems”: http://www.teamwavelength.com/downloads/ notes/an-ld09.pdf The output switched off unexpectedly The instrument detected an internal error. (See Error Messages on page 24.) Switch the back panel power button off and then on again, and turn the front panel power button on. The internal temperature has exceeded 70ºC. Allow the instrument to cool down and then press the front panel power button. 20 kHz noise is in the output current QCL driver is operating in current limit. If safe for the quantum cascade laser, increase the output current limit setting. When actively operating in current limit, the safety circuits add noise to the output. If I run my QCL at about 5% of maximum output current, the transfer function becomes non-linear and I see distortion in my output current waveform. QCL driver resolution is too low. Select a QCL driver with a much lower maximum output current. For example, to run 50 mA, request a QCL125 (125 mA maximum output). My instrument doesn’t show up in the list. (Remote Only) Your instrument may not be turned on. Power up the instrument and click Refresh on the Choose Instrument window. Your instrument may not be plugged in to the computer. Check that either a USB or Ethernet cable is tightly connected to the instrument and to the computer. Your instrument may be on a different sub-net. Add the sub-net to the Choose Instrument window and then click Refresh. Actual current does not match the setpoint. The setpoint exceeds the limit current setting. If the limit current can be increased without damage to the QCL, increase the limit current setting. The QCL is compliance voltage limited. Increase the Max Supply Voltage slightly to see if actual current increases. Follow the instructions on page 25 to optimally set the Max Supply Voltage.
