Seller: Valuetronics International Inc

Agilent Keysight HP 44711A The 44711A is a Data Logger from Agilent. Data loggers, or

The 44711A is a Data Logger from Agilent. Data loggers, or data recorders, collect information over time for a variety of purposes. A data logger uses internal memory and sensors to gather and document information on a 24-hour basis. Receive an accurate and comprehensive picture of the environmental conditions you’re monitoring as the device logs this information around the clock. Use data logging to measure temperature, humidity, wind speed, solar radiation, soil moisture levels, road traffic, tank levels, and a number of other elements.

Product specifications of Agilent 44711A (From Used-Line T&M Specifications)

  • Launch Date
  • Alternative No replacement.
  • See also 44712A, 44713A
  • Status Discontinued by Manufacturer

The HP 44711A is a 24-channel high-speed FET multiplexer that directly multiplexes voltage, resistance, thermocouples, and strain gages. The 44711A maximizes measurement throughput and increases system reliability.

  • Maximum switch rates: 5500 channels/second from back-plane, 100000 channels/second from ribbon cable
  • Up to six (eight with extender) high-speed FET multiplexers can be controlled through the ribbon cable
  • The 24-channel multiplexers switch high and low only. Each floating input is balanced (equal impedance between high-to-chassis and low-to-chassis) to provide good common mode rejection
  • FETs have no mechanical limitations, as there is no wearing out due to switching 
  • Maximum input voltage: Rear and back-plane input protected to 16 V peak. With analog back-plane disconnected from multiplexer, the back-plane voltage can go up to 42 V peak
  • Maximum input current: 1 mA per channel
  • Input impedance
    • Power on resistance: >108 Ω
    • Power off resistance with Vin 10 V: >1000 Ω
    • Power off resistance with Vin >10 V: >200 Ω
    • Maximum capacitance at 1 MHz: 200 pF
  • Closed channel path resistance: 3.1 kΩ
  • Bandwidth: 1.0% flatness at 20 kHz, -3 dB bandwidth at 200 kHz
  • Crosstalk: -50 dB at 10 kHz, -35 dB at 100 kHz
  • Maximum offset voltage: 15 µV at 0 to 28° C, 185 µV at 28 to 55° C
  • Maximum bias current
    • Current sourced by High or Low to Chassis into Input Terminals or back-plane, with isolation relays closed: ±5 nA DC at 0 to 28° C, ±15 nA DC at 28 to 55° C
    • Current sourced by High or Low to Chassis into back-plane, with isolation relays open: ±1 nA DC at 0 to 55° C
  • Maximum wire size: 16 AWG
