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.
