Data Sheet
• 1-Slot, C-size, register based
• DCV, ACV, 2- & 4-wire Ω, temperature
• 5.5-digit low-noise integrating A/D
• 13 kHz high-speed sampling A/D
• Balanced differential isolated inputs
• Software calibration
Description
The Agilent Technologies E1411B 5.5-Digit Multimeter is a
C-size,1-slot, register-based VXI module. It is identical in electrical design to the E1326B, differing only in size. You can use the
integrating A/D to make 5.5-digit, low-noise measurements,
or switch to the sampling A/D to make 14-bit readings at rates
up to 13 kHz.
When combined with any Agilent VXI relay or FET multiplexer,
you can create a multichannel scanning multimeter. For example,
by sending just one SCPI command to the E1406A, you can
program the multimeter and the channels of your multiplexers
all at one time. The E1411B provides flexible triggering with
built-in timer pacer, also.
Product functions for this DMM include Vdc/ac, 2- and 4-wire
Ω, offset-compensated Ω, thermocouples thermistors,and
RTDs. This autoranging DMM is especially well suited for data
acquisition and computer-aided test applications.
Refer to the Agilent Technologies Website for instrument driver
availability and downloading instructions, as well as for recent
product updates, if applicable.
