Choosing between two data acquisition recorders often comes down to a simple question: do you want the lower-priced system or the mainframe-style investment? The Keysight DAQ970A and Keithley DAQ6510 sit on opposite sides of that decision, with a $1,000 gap between their listed prices. Here's how to make the call without overthinking it.
Quick verdict
If your priority is a lower entry price and a system that pairs data acquisition with a DMM6500 multimeter, the Keithley DAQ6510 is the lower-priced pick. If you'd rather spend more on a mainframe from Keysight, the DAQ970A is the straightforward path. The real decision comes down to which trade-off fits your bench.
At a glance
| Model | Listed price | Condition | Price bar |
|---|---|---|---|
| Keysight DAQ970A Data Acquisition System Mainframe | USD 2,600.00 | New - Open box | |
| Keithley DAQ6510 Data Acquisition DMM6500 Multimeter System | USD 1,600.00 | Used |
Where each product wins
- Keithley DAQ6510 wins when you want the lower listed price and the DMM6500 multimeter system in the same package.
- Keysight DAQ970A wins when you want a mainframe from Keysight and the higher listed price fits your budget.
Keithley DAQ6510 Data Acquisition DMM6500 Multimeter System
The Keithley DAQ6510 makes sense when price is the first number you look at. At $1,600, it costs $1,000 less than the Keysight, and that savings can go toward other gear. This is a used unit, so the condition is the main trade-off. It's a 2-slot system, which is worth factoring into your channel-count planning. The DMM6500 multimeter system in the name points to measurement capability built into the same package rather than a separate meter. For someone building a first data acquisition station or adding a second bench without stretching the budget, the DAQ6510's combination of lower price and integrated multimeter functionality is hard to ignore. Just go in knowing that "used" means the unit's history matters, and you should inspect it carefully.
Keysight DAQ970A Data Acquisition System Mainframe
The Keysight DAQ970A takes the opposite approach: pay more upfront for a mainframe with a "New - Open box" condition. That condition means it's new but the box has been opened. The $2,600 price is the highest in this pair, and that's the commitment you're making. You're getting a Keysight mainframe, so the form factor is a mainframe rather than an integrated multimeter system. The trade-off is that you're paying $1,000 more for this unit than for the Keithley. If your priority is getting a clean mainframe and you have room in the budget, the DAQ970A is the more straightforward choice. If you want the lowest possible spend, the extra $1,000 is a lot to tie up in a mainframe.
Final choice by use case
Choose the Keithley DAQ6510 if your budget is the deciding factor and a 2-slot system covers your needs. Choose the Keysight DAQ970A if you're building around a mainframe and can stretch to the higher listed price.
