Fully Programmable via GPIB, RS232 or USB
The QL355TP incorporates a full bus interface permitting remote control and readback via either
GPIB (IEEE-488), RS232 or USB.
The GPIB interface conforms fully with IEEE-488.2 and IEEE-488.1.
The serial interface can be used as a conventional RS232 interface or as part of a multi-
instrument ARC system (Addressable RS232 Chain).
USB represents the future for medium speed PC connectivity. By adding USB hubs, multiple
devices can be connected. A Windows device driver is supplied which creates a virtual COM
port, enabling USB to be used with applications that do not directly support it.
QL series supplies use simple and consistent command structures which make programming
particularly easy regardless of which interface is used.
A National Instruments LabWindows* device driver is available.
All power supply settings can be controlled via the bus. Voltage and current can be set to a
resolution of 1mV or 0·1mA. Actual voltage and current can be read back together with the power
supply status.
