Remote Control of LAB Series Instruments
REMOTE INSTRUMENT CONTROL
Wavelength's Virtual Instruments offer higher level remote
control based on the Command Set for these TMC class
instruments. See the
LAB Series Instrument Command Set
document for lower level control.
These free applications are executable files that use the
National Instruments Run Time Engine.
One of each type of instrument can be operated at a time.
If you would like different default values or functionality,
or the full VI, contact Technical Support. Custom Virtual
Instruments can easily be coded.

Summary of Contents for Wavelength Electronics LAB Series
- Page 1 VIRTUAL INSTRUMENT Remote Control of LAB Series Instruments QCL LAB, TC LAB, LDTC LAB REMOTE INSTRUMENT CONTROL Wavelength's Virtual Instruments offer higher level remote control based on the Command Set for these TMC class instruments. See the LAB Series Instrument Command Set document for lower level control.
- Page 2 QCL Software Downloads page, click Stop: Use the Stop button to gracefully end the LabVIEW Interface for QCL LAB Series Instrument remote control of the instrument. Any commands and download it to the computer. in process are completed prior to ending remote control.
- Page 3 SETTINGS & MONITORS TAB MONITORS The Settings & Monitors tab is used as the main control for Actual QCL Current (A): Monitor output current, in Amps, to remote operation. the load. Power: The Power button functions the same as the front Actual QCL Voltage (V): Monitor output voltage, in Volts, to panel power switch on the instrument.
- Page 4 VI SCAN TAB Perform a VI characterization scan of the QCL load. Input scan settings, file name and location to store the scan data, and start or stop the scan. Current Start (A): In the Current Start control, type the current, in Amps, at which to start the VI scan.
- Page 5 DATA LOGGING TAB The chart display starts when the Virtual Instrument application starts. It displays the last 17 minutes of data. Interval (sec): In the Interval control, type the desired interval, in seconds, for data to be recorded. The range is 1 to 10 seconds. Log Data button: Click this button to start or stop logging output current and current limit data to a file.
- Page 6 TC Software Downloads page, It is NOT recommended to use this method of stopping click the LabVIEW Interface for the TC LAB Series and the application. Instead, use the STOP button. download it to the computer. Stop: Use the Stop button to gracefully end 2.
- Page 7 SETTINGS & MONITORS TAB The Settings & Monitors tab is used as the main control for remote operation. Figure 7. Settings & Monitors Tab Power: The Power button functions the same as the front Temp Limit Min (°C): In the Temp Limit Min control, type the panel power switch on the instrument.

- Page 9 SENSOR TAB The Sensor tab is where the active sensor is chosen, custom sensors are created, or bias currents are adjusted. Figure 8. Sensor Tab Active Sensor: Shows the sensor that is currently selected Set as Active Sensor: Set the sensor profile selected with for use with the TC LAB instrument.
- Page 10 Calibration Coefficients: Depending on the choice of sensor, Custom Sensor Type: Choose a sensor type for custom different calibration options will appear. sensor configuration. A sensor name and parameters below must also be configured before the Create Custom Sensor • Thermistor (Steinhart-Hart) button is pushed.
- Page 11 TEMPERATURE SCAN TAB The Temperature Scan tab allows plotting and saving of temperature (actual and set) as a function of time, over a range of temperatures defined in the controls of this tab. Note that while the functionality of the Temperature Scan in the VI is the same as that on the front panel of the instrument, the commands to carry this scan out are different.
- Page 12 DATA LOGGING TAB The chart display starts when the Virtual Instrument application starts. It displays the last 17 minutes of data. Figure 13. Data Logging Tab Interval (sec): In the Interval control, type the desired interval, in Actual Temperature (°C): The actual temperature is shown in seconds, for data to be recorded.
- Page 13 ADDITIONAL SETUP TAB The Additional Setup tab is where profile names can be edited, added, and saved. Additionally, cable resistance, tolerance parameters, remote enable, and laser shutdown signal polarity are set on the Additional Setup tab. Figure 14. Additional Setup Tab Existing Profile Name: Click in the field to list all of the existing Tolerance Parameters: Sets parameters that will enable the profile names stored on the TC LAB instrument.
