Page 5: General Safety Information
PicoQuant GmbH PPx 512 Manual 1. General safety information CAUTION! Before using this device, make sure that you have read and understood the con- tent of this user manual. Store this documentation in a safe and easily accessible place for future reference. -
Page 6: Electrical Safety Instructions
WARNING! Visible and invisible laser radiation The PPx 512 can emit visible, infrared or UV laser light. Infrared or UV light is not visible to the eye! This laser can emit laser light of up to class 3b / IIIb. Please refer to the labels affixed to the laser housing for information on classification. -

Fig. 1: Example of laser warning, certification, and classification label. Please refer to the laser delivery report in the Appendix for information on the central emission wavelength, maximum achievable optical output power, and pulse shape of the delivered PPx 512 laser. CAUTION! -
Page 8: Introduction
Additional external signal input is available to control the reading of the sequence. Synchronization output: A synchronization signal is output by the PPx 512, that signals the full period of all 512 bytes, i.e. every 102.4 ns. Controlling and Programming over Virtual COM-Port: The PPx 512 can be OS independent controlled over a human readable ascii terminal (Windows: TeraTerm;... -

(BIST). Within this test the TEC is set to the stored temperature and waits for settling. If BIST was successful the latest waveform date is loaded to the RAM and the laser turns on. Now PPx 512 enters the WORKING state and load the latest waveform in the RAM of the waveform generator. -
Page 12: Working
While WORKING the PPx 512 is active and the laser output is on. It checks also periodically the TEC temper- ature and the external power supply. If one or both are out of limit the PPx 512 changes to ERROR state and turn off all internal power supply and also the laser output. -
Page 13: Write Waveform To Ppx 512
Write waveform to PPx 512 For writing new waveform data to PPx 512 the interface have to be set to data mode. This is done by sending SYS:DATA! The interface responses with ACK and now accepts only characters which are used for hexa- decimal representation (0..9, A..F, a..f, x). -
Page 14: Synchronization Output
Fig. 5 shows the relation between SYNC and optical out. OP Mode is left open so PPx 512 is in free-running mode. The optical output is measured with Tektronix SA-42 optical to electrical converter. For correct under- standing of Fig. -
Page 15: Operation Mode (Op Mode)
102.4 ns the repetition is limited to ~9.766 MHz. If no signal is applied to OP Mode the PPx 512 reads periodically the RAM content, i. e. after reading byte 511, reading starts again at byte 0. This is also true for a high signal (0.75 to 1.1 V) at OP Mode. -

PicoQuant GmbH PPx 512 Manual 7. PPx512 Control PPx512 Control is a LabView based frontend to programm a desired waveform into the PPx 512. 7.1. Installation The PPx512 Controller software can be distributed on CD, via download or via email. If you received the package via download or email, it may be packed in a zip-file. -
Page 20: Using Ppx 512 Control
Using PPx 512 Control Connect the PPx 512 to the PC by using the USB cable and power up the device. If the status LED at the PPx 512 is green, the PPx512 Control software can be started. The actual waveform is read out and will be displayed. - Page 21 The current values displayed in the graph display are not directly transferred to the hardware. In order to up - date the RAM of the PPx 512 one has to select the menu item Device → Write or keyboard shortcut Ctrl + W.

Page 24: Waveform Design
The actual optical waveform may be differ from the set signal. In addition every laser diode may produce a different optical output while the set signal is the same. That's why every PPx 512 will generate a slightly dif- ferent optical waveform. - Page 25 PicoQuant GmbH PPx 512 Manual Temperature range is limited to factory set ± 8°C and also limited to maximum 50°C.
