Tektronix, a US-based company, has introduced two new Keithley 6½-digit models to its line of Digital Multimeters (DMMs) and data-acquisition systems: The new DMM6500 DMM and also the new DAQ6510 data-acquisition system. The company has also upgraded their Kickstart measurement software to version 2.0.
Keithley has long been a dominant provider in the 6½-digit DMM market. With the DMM6500 and DAQ6510, the company looks forward to strengthening its position further. Both of these new instruments use the same touchscreen UI (with pinch gesture) first unveiled with the company’s 7½-digit DMM7510.
With a base price of $1140 (same as previous models), the DMM6500 hits a sweet spot for bench and production measurements. In addition to its 6½ inch display, the DMM6500 also features a 16-bit, 1 Msample/s digitizer and can display voltage and current waveforms over time. It can store up to 7 million readings in internal memory.
Like its previous models, the DMM6500 is also expandable to ten channels. It uses the same expansion cards as models in the 2000 series DMMs. The DMM also maintains software compatibility with Keithley’s 2000 series models, minimizing software changes. It also emulates software commands for the now obsolete but still in use HP/Agilent/Keysight 34401A.

Communications and channel expansion:
- Interfaces: LAN LXI and USB-TMC standard. GPIB with digital I/O ($225), RS-232 with digital I/O ($200), or TSP-Link with digital I/O ($200).
- Multichannel measurement capacity: 10 channels with two card options (10 channels voltage/current ($628) or 9 channel temperature/general-purpose inputs ($700)
Based on the DMM6500, the DAQ6510 ($1750 system only, $2230 with 20-channel scanner card) support up to 80 channels using two 40-channel cards. Keithley offers twelve switch modules, which are the same as used in the 2700-series data-acquisition DMMs. Scanning speed is 800 channels/s across multiple systems connected through Keithley’s TSK Link. The GPIB and RS-232 interface modules are also supported.
