the View Settings button

V-Span

(Voltage Span Control)

The voltage adjustment range can be controlled by digital setting of the end-stop values of

the coarse voltage control to any desired values. The range for Vmax is 1V to 120V or 250V

depending on model. The range for Vmin is 0 to (Vmax – 1V).

DIGITAL BUS INTERFACES (PLH-P models only)

The standard PL-P product offers full remote control and read-back using RS-232, USB or LAN

(LXI-C). All interfaces are at ground potential and opto-isolated from the output terminals.

Note: Remote/Local Sense, and Operational Mode (PL303QMD-P) are manually selectable only.

RS-232

Standard 9-pin D connector. Baud rate 9,600.

USB

Standard USB 2.0 connection (backwards compatible with USB 1.x). Operates as a virtual

COM port.

Ethernet (LAN)

Standard 10/100 base-T hardware connection. ICMP and TCP/IP Protocol for connection to

Local Area Network or direct connection to a single PC.

LXI Compliance

LAN interface is compliant with LXI-C. (LXI is the abbreviation for Lan eXtensions for

Instrumentation). For more information visit: www.tti-test.com/go/lxi

GPIB INTERFACE (Option G, factory fit only)

Option G adds a GPIB (IEEE-488) interface.

This is in addition to the RS-232, USB and LAN interfaces of the standard PL-P product. The

interface conforms with IEEE-488.1 and IEEE-488.2

Set Voltage Input: 0V to 10V sets 0 to 100% of rated output (e.g. 0 to 120V for PLH120-P).

Alternative scaling of 0V to 5V (selectable using internal link).

Set Current Input: 0V to 10V sets 0 to 100% of rated output (0 to 750mA for PLH120-P).
