FET Multiplexer
Description
The Agilent E1351A, E1352A, E1353A, E1357A, and E1358A FET
Multiplexer is an "instrument" in a VXIbus mainframe. As such, each FET
Multiplexer is assigned an error queue, input and output buffers, and a status
register.
NOTE
Instruments are based on the logical addresses of the plug-in modules. See
the Agilent 75000 Series B Installation and Getting Started Guide to set the
addresses to create an instrument.
The FET Multiplexer Module consists of a component assembly and a
terminal block. There are five different terminal blocks, one for each
application. The component assembly is the same for all applications. The
applications supported by the component assembly are:
•
Agilent E1351A 16-Channel FET Multiplexer
• Agilent E1352A 32-Channel Single Ended FET Multiplexer
• Agilent E1353A 16-Channel Thermocouple FET Multiplexer
• Agilent E1357A 8-Channel 120
Ω
Strain Gage FET Multiplexer
• Agilent E1358A 8-Channel 350
Ω
Strain Gage FET Multiplexer
Each terminal block configures the component assembly to the appropriate
type of switch. The terminal card also contains the model identification code
and installation of the terminal card before applying mainframe power
ensures that the type of switch is properly identified. Optionally, the model
identification can be set on the component assembly to allow it to be
correctly identified without a terminal card installed.
Agilent E1351A
Description
The
Agilent E1351A
provides high speed switching for up to 16 channels.
The channels are numbered 00 to 15. Each channel provides connections for
High (HI), Low (LO), and Guard (G), although only High and Low are
switched. Guard for each channel is connected to chassis ground through a
10 k
Ω
resistor.
Agilent E1352A
Description
The
Agilent E1352A
provides high-speed switching for up to 32 channels.
The channels are numbered 00 to 31. A High (HI) connection is provided
for each channel. Low (LO) and Guard (G) are common for all channels.
Agilent E1353A
Description
The
Agilent E1353A
is identical to the Agilent E1351A, but contains a
temperature reference thermistor on the terminal block to allow
thermocouple temperature measurements when combined with either the
Agilent E1326A or E1411B Multimeters.
