Photodetector with USB output- PD-USB
|
|
Product Summary
General Photonics is pleased to offer an industry first photodetector with USB output! The new device,
the PD-USB, allows a detected optical signal to be directly input to a personal computer (PC) for further processing,
with no need for expensive oscilloscopes, analog cards, A/D cards, or GPIB hardware. Designed specifically
to be used in laboratory environments, the PD-USB comes complete with a photodetector, low noise amplifier,
A/D converter, digital USB interface, LabVIEW driver, and software. The software enables the display and analysis
of optical signals in both the time (oscilloscope mode) and frequency (spectrum analyzer mode) domains.
The device also has a trigger port for synchronization with a trigger signal, and can display the output
on a PC screen, just like a digital oscilloscope. For added convenience, an analog output port allows the detected
signal to be displayed on an oscilloscope or a voltmeter. Both the transimpedance gain and bandwidth
can be adjusted with a rotary switch. 4 strong magnets allow the PD-USB to be conveniently and
securely fixed to an optical table during an experiment. Alternatively, it can be mounted on an optical
post with a laboratory standard 1/4-20 screw. The PD-USB makes your research easier with the speed and
convenience of USB.
