1-2 11713A Operating and Service Manual
Agilent Technologies 11713A Attenuator/Switch Driver
Overview
Overview
The 11713A attenuator/switch driver is an GPIB compatible
instrument designed to provide control of up to two four-section
programmable step attenuators and two microwave coaxial switches.
Features • Instrument control is accomplished manually from front panel
pushbuttons or automatically over the GPIB interface bus.
• Programing via the GPIB can be accomplished in simple one line
statements.
• The attenuator/switch driver features front panel status monitoring
and a self-contained power supply with current limiting.
• The instrument includes solenoid arc suppression diodes and has
common terminal supplies of +24 Vdc.
• Connections are made at the rear panel to the ten pairs of current
sinking transistors
❍ Five contact pairs per set are present at each rear panel
multi-pin plug. This plug mates with the attenuator drive cable.
❍ The remaining two contact pairs are connected to the banana
jacks mounted on the rear panel. The banana jacks are
available for driving the coaxial switches or for optional
applications.
❍ Each pair of contacts is individually programmable via GPIB or
from the front panel pushbutton.
❍ The contact pair status is indicated by the front panel LEDs in
the appropriate pushbutton
❍ The contact pairs 9 and 0 can be used to switch between one of
two loads or to reverse the current through a single load.
Options The Option 907 front handle kit contains front panel handles that can
be added to the driver cabinet.
The Option 908 rack adapter kit contains the flange and hardware for
mounting the driver in a standard rack of 48.3 cm (19 inches).
