Description
The HP E1357A 120 Ω Strain FET Multiplexer is a
B-size, 1-slot, register-based VXI module. This relay
multiplexer provides bridge completion and excitation
voltage (4.6 V) circuitry for eight channels. Each
multiplexer module consists of a B-size component
card (labeled E1351-66201) and a screw terminal block
that plugs onto the component card. The HP E1357A is
functionally similar to the HP E1351A, E1352A, E1353A,
and E1358A.
You can perform dynamic strain gage measurements
with automatic conversions to engineering units on
multiple multiplexer channels by sending SCPI
commands to either the HP E1326B or HP E1411B.
Strain measurements supported by SCPI with the
HP E1326B and E1411B DMMs include: Quarter,
Bending, Half, Poisson Half, Bending Full, Poisson Full,
Bending Poisson Full. The FET multiplexer cannot
perform tension shunt nor compression shunt
diagnostics.

—CALibration:STRain (@100:107)
Measure a Half Poisson bridge:
—MEASure:STRain:HPOisson (@100:103)
Strain measurements supported in SCPI with the above
HP DMMs include:
—Quarter
—Bending Half
—Poisson Half
—Bending Full
—Poisson Full
—Bending Poisson Full
Diagnostics include:
—Leadwire Resistance
—Internal Half Bridge Voltage
—Guard Voltage
—Bridge Excitation Voltage
—Tension Shunt Diagnostic (not available)
—Compression Shunt Diagnostic (not available)
Configuration
One analog bus cable is shipped with each module,
making it easy to connect multiplexer common outputs
together for slot-adjacent modules. If you are using a
B-size mainframe, HP E1300A/B or HP E1301A/B, use
the analog bus cable shipped with the HP E1326B DMM
to connect it to the multiplexer(s).
C-size Adapter
For installing the HP E1357A in a C-size mainframe, the
HP E1403C active adapter is recommended.
