The Agilent 34970A is an exceptional data logger device offered by ValueTronics. With its modular design, the 34970A can be scaled from 20 to 120 channels, allowing for seamless expansion. Whether used independently or in conjunction with a computer, this device is perfect for a wide range of applications. Its compact size and durable features make it highly portable, and its small footprint makes it ideal for benchtop testing. Additionally, the 34970A Agilent Data Logger offers standard GPIB (IEEE 488) and RS-232 interfaces, enabling test automation for added convenience.
What’s more, each channel is independently configurable. This means you can configure channel 1 for DCV, channel 2 for a K-type thermocouple, and channels 3 and 13 for a 4-wire RTD measurement, all on the same module, all in a single scan. For custom linear conversions, use the Mx+B scaling function on any channel. You can even display a custom 3-character engineering label like RPM or PSI to identify your measurement units.
Alarms are available on a per-channel basis as well. Enter a high limit, a low limit, or both. The unit compares each reading to its limits and flags any out-of-range measurements. You can assign one of four TTL alarm outputs to any input
channel to trigger external alarm lights, sirens, or send a TTL pulse to your control system, all without a PC connected.
This unit automatically builds a scan list that includes all configured inputs (even digital inputs from the Agilent 34907A multifunction module) in ascending order by channel number. You can pace scans by setting the unit’s internal timer for automatic scanning at a specific interval, by manually pressing a front-panel button, or by sending a software command or external TTL trigger pulse.
FYI – Keysight Technologies, Agilent Technologies, and HP (Hewlett Packard) are the same Test and Measurement Company. For more info – check out our blog: Understand the Difference Between HP, Agilent, and Keysight
