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. OUT CONNECTOR
. This SMA connector is connected to the output module, when the
output module is used to drive a diode load. If the output module is not used, this
output will generate up to 250V into a load impedance of 50Ω.
Caution: Voltages as high as 250V may be present on the center conductor of this
output connector. Avoid touching this conductor. Connect to this connector using
standard coaxial cable, to ensure that the center conductor is not exposed.
10. CONTROL Connector
. This DB-9 female connector should be connected to the
corresponding connector on the output module using the supplied DB-9 cable. This
cable contains the wiring for the output module cooling fan and the output module
thermistor.
11. M Connector
. (Optional feature. Present on "-M" units only.) The monitor output
provides an attenuated replica (-20 dB, ÷ 10) of the voltage on the main output. The
monitor output is designed to operate into a 50 Ohm load.
