1-8 Programming Guide

Preparing for Use ESG Family Signal Generators

Setting up the Equipment for Remote Operation

Connecting the Interface

1. Attach the male end of the RS-232 cable to the signal generator’s rear-panel

AUXILIARY INTERFACE connector.

2. Attach the female end of the RS-232 cable to the null modem.

3. Using a 5-mm nut driver, remove both standoffs from the female-to-female adapter.

4. Connect one end of the modified adapter to the null modem and the other end to the

selected port on the computer.

• For personal computers, make the connection to the COM2 RS-232 port. COM1 is

acceptable if available.

• For UNIX workstations, connect to the /dev/tty00 port. Alternatively, /dev/tty01 may

be used if it is available.

Configuring the Interface

1. Set the signal generator’s baud rate.

Press

Utility > GPIB/RS-232 > RS-232 Baud Rate. The default RS-232 baud rate is 19200.

Use baud rates 19200 or lower only. Press the appropriate softkey to adjust the signal

generator’s baud rate to the baud rate of your personal computer or UNIX workstation.

2. Set the signal generator’s handshake.

Press Utility > GPIB/RS-232 > RS-232 Pace. To determine the hardware operating

parameters, you need to know whether DSR (data set ready) and CTS (clear to send) are

active during communication with the controller, and the baud rate expected by the

controller. Set the signal generator’s handshake accordingly.

3. Set the signal generator’s RS-232 echo.

Press

Utility > GPIB/RS-232 > RS-232 Echo Off On to the desired operating state for your

configuration.

4. Set the signal generator’s remote language.

Press

Utility > GPIB/RS-232 > Remote Language. The only remote language supported by

RS-232 is SCPI (standard commands for programmable instruments).

If SCPI is not highlighted, press SCPI to select it.

Verifying the RS-232 System Interface

The following command verifies that the serial interface functions. With the equipment set

up as described in the previous sections, clear and reset the controller. Execute the

following command: OUTPUT "*IDN?"

The signal generator should return a string similar to the following, depending on model:

<instrument model name and number>, US37040098 B.03.00

If not, verify that the RS-232 parameters are set correctly (see “Setting Up the Interface

for GPIB Operation” on page 1-5) and that the interface cable is properly connected.
