1 General Information

This part of the programmer’s reference manual contains specific information about the SCPI

command set of the Series 4000 instruments. A general description is followed by explanations

of how to use the SCPI commands. The command set is according to the SCPI 1999.0

standard.
The Series 4000 instruments provide a USB 2.0 Full Speed link according to the USB 2.0

specification, the USBTMC specification and the USBTMC USB488 specification.
The instrument’s command buffer accepts commands with a maximum length of 255

characters. The instrument’s message output buffer can contain response messages of up to

255 characters.
There are VXIpnp/VISA instrument drivers available for Series 4000 instruments. See

www.thorlabs.com

for downloads.
