The 44713A 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. Additional Features:
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
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, ±45 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
Reference junction compensation accuracy: 0.1° C
Maximum temperature difference across isothermal module: 0.2° C
The Agilent HP 44713A is a 24-channel high-speed FET multiplexer that directly multiplexes voltage, resistance, thermocouples, and strain gages. The Agilent HP 44713A maximizes measurement throughput and increases system reliability.
