When triggering externally, the instrument can be set such that the output pulse
width tracks the pulse width on this input, or the output pulse width can be set
independently.

6. GPIB Connector

. A standard GPIB cable can be attached to this connector to allow

the instrument to be computer-controlled. See the “Programming Manual for -B
Instruments” for more details on GPIB control.

7. RS-232 Connector.

A standard serial cable with a 25-pin male connector can be

attached to this connector to allow the instrument to be computer-controlled. A user
name (“admin”) and a password (“default”, as shipped from the factory) are required
when logging into a serial terminal session. The internal controller attempts to auto-
sense the parity setting. It may be necessary to send a few return characters before
attempting a login in order to provide enough data to allow this auto-sensing to work.
(A standard Linux “agetty” process is used to implement serial control internally.) See
the “Programming Manual for -B Instruments” for more details on RS-232 control.

8. Network Connector

. (Optional feature. Active on -VXI units only.) This Ethernet

connector allows the instrument to be remotely controlled using the VXI-11.3, ssh
(secure shell), telnet, and http (web) protocols. See the “Programming Manual for -B
Instruments” for more details.

9. AMP Connector

. (Optional feature. Present on -EA units only.) The output amplitude

can be set to track the voltage on this input. Zero Volts in corresponds to zero
amplitude output, and +10V in corresponds to maximum amplitude out. This mode is
activated by selecting "Ext Control" on the front-panel amplitude menu, or with the
"source:voltage external" command.
