Agilent E1411B 5.5-Digit Multimeter, C-Size 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.
