Command line interface
Common test procedures can be accomplished using the generator’s physical controls on
the front panel, Virtual Front Panel or through the command line interface. The generator
supports an ASCII command and query language that allows you to control the generator
interactively or through batch processing of command files. All generator functions are
supported through this interface. The command line interface is available through three
physical interfaces:
• Serial (RS-232) interface (terminal session, such as HyperTerminal, via the serial port)
• Ethernet network interface (Telnet session or Web browser via the Ethernet port)
• GPIB (IEEE-488) interface (via the GPIB port)
The serial and Ethernet interfaces are described in this section. For information on the
GPIB interface, see Chapter 5, “
Using GPIB Interface .”
Working with the serial interface
This section describes how to connect the generator to the PC via the serial port, how to
establish a terminal session with the generator using a terminal emulator such as
HyperTerminal, and how to change serial port settings.
To connect the generator to the PC:
To set up the generator to use the serial interface, connect a serial null modem cable from
the serial port of the PC to the SERIAL connector on the rear of the generator.
Establishing a terminal session with the generator
The following procedure describes how to establish a terminal session with the generator
through the serial port. For information about establishing a Telnet session over an
Ethernet LAN, see “
Establishing a Telnet session with the generator ” on page 34.
To establish a terminal session with the generator:
1. Open a terminal emulator, such as HyperTerminal. Configure the terminal emulator to
use the parameters set in the generator. By default, the generator’s serial port is set to
9600 baud, 8 data bits, no parity, 1 stop bit, no flow control.
2. Establish a terminal connection with the generator. Press Enter until the C:> prompt
appears.
