Here is a list of laboratory instruments and common issues in remote control

**Oscilloscope LeCroy 625Zi**\\
BW: 2GHz\\
OS: Windows 7\\
Connection types: USB-GPIB, Ethernet\\
  * USB: be sure to enable remote control from oscilloscope menu Utilities > Remote\\
  * Ethernet: \\
Team Viewer: the instrument has TW installed. Install TW on your pc to control the oscilloscope from your machine\\

**Oscilloscope LeCroy 6100A**\\
BW: 1GHz\\
OS: Windows XP\\
Connection types: USB-GPIB, Ethernet\\
Note: this device needs a non standard GPIB connector, micro-d25 to GPIB converter is needed (rare)\\

**Picosecond laser**\\
Pulsed laser diode (3B class)\\
Power: 1200 mW\\
Wavelengths: 1064 nm, 405 nm\\
Connection types: serial (RS232, USB-serial)\\
Note: needs RS232 male-male cable (!), in case you don't have one, use USB connection. The connection can be displayed from Control Panel > System > Devices on your pc as UART (USB emulating serial) e.g. on COM3 port, then configure the serial connection as following:\\
   * Baud rate: 19200
   * Bits: 8
   * Stop bits: 1
   * End of command: carrier return \r (the instrument recognize the command only after carrier return)
   * Command list: 
                   state > display system status
                   debug > display additional information
                   ld=(0 disabled, 1 enabled) > enable/disable laser
                   ld? > ask laser if enabled/disabled
                   tune=(0 max, 1000 min) > set laser attenuation
                   tune? > display laser attenuation
                   te=(0 falling, 1 rising) > set trigger edge
                   te? > display trigger edge

**HV CAEN**\\
4 channel high voltage +/- 5000 V DC\\
Change the channel polarity: positive polarity is set by default. To change the polarity of each single channel, open the instrument from top cover and flip the +- connector with the choosed sign on the side of the channel name.
