Agilent 34970A Data Acquisition / Logger

安捷倫 34970A 資料擷取/資料記錄切換裝置

多通道的電壓電流及溫度等不同數據的測量及收集, 可以很快速的掃瞄及記錄

在電腦端的軟體也很方便, 讓我在曲線記錄時很方便. (例如鋰電池的充放電效應)

Features

  • 3-slot mainframe with built-in GPIB and RS232 interfaces
  • 6 1/2-digit (22-bit) internal DMM, scanning up to 250 channels per second
  • 8 switch and control plug-in modules to choose from
  • Built-in signal conditioning measures thermocouples, RTDs and thermistors, AC/DC volts and current; resistance; frequency and period
  • 50k readings of non-volatile memory holds data when power is removed
  • Hi/LO alarm limits on each channel, plus 4 TTL alarm outputs
  • BenchVue software enabled: BenchVue DAQ Control and Analysis app enables you to create tests without programming

Description

The 34970A data acquisition / data logger switch consists of a three-slot mainframe with a built-in 6 1/2 digit digital multimeter. Each channel can be configured independently to measure one of 11 different functions without the added cost or hassles of signal-conditioning accessories. Choose from eight optional plug-in modules to create a compact data logger, full-featured data acquisition system or low-cost switching unit. On-module screw-terminal connections eliminate the need for terminal blocks and a unique relay maintenance feature counts every closure on every switch for easy, predictable relay maintenance. Our most popular module 34901A features a built-in thermocouple reference and 20 two-wire channels.

Key Features & Specifications

  • 20 Channel Multiplexer
  • Two- and four-wire scanning
  • 300 V switching
  • 60 ch/s scanning
  • Built-in thermocouple reference junction

Description

The 34901A module for the 34970A/34972A Data Acquisition/Switch Unit is the most versatile multiplexer for general purpose scanning. It combines dense, multi-function switching with 60 channel/second scan rates to address a broad spectrum of data acquisition applications.

Two- and four-wire channels can be mixed on the same module. Two additional fused inputs (22 channels total) route up to 1A of current to the internal DMM, allowing ac and dc current measurements without the need for external shunt resistors.
