Dual-Channel Multimeter Relishes High-Volume Manufacturing Chores

Tektronix introduces the Keithley DMM7512 dual channel 7½-digit sampling multimeter that packs two independent and identical digital multimeters into a low profile 1U high footprint. The instrument handles a range of demanding high-volume manufacturing test applications.


Eliminating the need for a separate instrument to capture waveform parameters, the DMM7512 enables users to capture transient signals and waveforms, as well as low-level waveforms such as battery drain currents, with its 1-Msample/s, 18-bit digitizer that has a voltage sensitivity of 1 µV and current sensitivity of 0.1 nA. With capacity to store 27.5 million time-stamped readings, each DMM can capture a waveform’s full profile and trigger on a variety of parameters.

For DC measurements on low power components, the DMM7512 provides 10 nV, 0.1 µΩ, and 1 pA sensitivities. It supports high accuracy, low resistance measurements with offset compensated Ohms, four-wire measurement, and dry circuit measurement. It also maximizes the test-uncertainty ratio for higher quality control with 1-year dc-voltage accuracies as narrow as 14 ppm.


For production environments, the DMM7512 executes test scripts using its Embedded Test Script Processor (TSP). This saves PC command communication time since the PC does not need to send a command for every instrument action. In addition, one DMM in the DMM7512 can be set up as the master controller both to execute test routines and to control other instruments through Keithley’s TSP-Link instrument-to-instrument interface.


The Keithley DMM7512 Dual Channel 7 ½-Digit Sampling Multimeter is available now, with pricing starting at $7,000. For greater details, checkout the DMM7512 datasheet.
