RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling
2 MB. Its primary purpose was to provide me with ready access to commonly needed
formulas and reference material while performing my work as an RF system and circuit
design engineer. The World Wide Web (Internet) was largely an unknown entity at
the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps
while typing up your telephone line, and a nice lady's voice announced "You've Got
Mail" when a new message arrived...

September 27, 2011 Press Release
September 27, 2011 -- Leverage your low-noise, high-stability Wavelength
Electronics laser control system with the budget-friendly USBKIT interface
board and software package. The bus-powered USB 2.0 interface board
is easily wired using on-board screw terminals and the QuickConnect™
virtual control panel provides out-of-the-box functionality with strip
chart graphs that show real-time laser system status.
diode driver and one temperature controller can be simultaneously operated
with the USBKIT. Multiple USBKITs can be attached to the same computer,
allowing for control of complex systems.
the full-featured graphic user interface you can set the desired load
temperature as a voltage or a temperature, maximum and minimum temperature
limits can be established, as well as whether laser diode current is
disabled if temperature limits are exceeded. Temperature sensor calibration
is easy with the built-in resistance-to-temperature conversion functions.
- Factory-modified National Instruments multifunction I/O card
includes D/A for remote setpoint control, and auxiliary A/Ds for
- The software controls one laser diode driver, one temperature
controller, and features graphing and data logging.
- Setup configuration can be saved for repeating experiments or
- The QuickConnect software includes on-screen wiring diagrams
for the connected Wavelength modules, making set-up a snap.
The software provides control of the laser drive current in constant
current mode, or photodiode current in constant power mode. Photodiode
current is easily converted to laser output power, and the drive current
limit is displayed on-screen.
Two strip charts graph data as
a function of time. Raw voltages, as well as translated current and
temperature values are available. One graph is associated with data
from the temperature controller, and the other displays laser diode
controller data. Auxiliary monitors can be associated with either graph,
and all data can be logged whether it's displayed or not.
your application requires additional functionality, program customization
Wavelength Electronics has simplified advanced
laser diode drive and thermal control technology for OEM and research
