BEAVERTON, OR—Tektronix on Thursday introduced the Keithley DMM7512 dual channel 7½-digit sampling multimeter, which packs two independent and identical digital multimeters into a low-profile 1U high, full rack width space-saving enclosure.
Featuring density and performance, the DMM7512 is suited for a range of demanding high-volume manufacturing test applications that require measurement capacity, performance and a compact footprint.
With volumes and demand ramping up, manufacturers producing products and components such as laser diodes for 3D sensing, mobile devices, automotive sensors and IoT devices need to minimize test costs, minimize the quantity of test equipment, and minimize floor and rack space consumption. They also need to ensure sufficient test capacity and performance to meet production requirements. Currently, all other 7 ½-digit, high accuracy DMMs fall short of meeting these requirements, providing only a single-channel in a 2U high, half-rack width chassis.
Eliminating the need for a separate instrument to capture waveform parameters, the DMM7512 enables test engineers to capture transient signals and waveforms, even low level waveforms such as battery drain currents, with its 1Msample/s, 18-bit digitizer that has voltage sensitivity of 1µV and current sensitivity of 0.1nA. 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 10nV, 0.1µΩ, and 1pA 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 14ppm.
For production environments, the DMM7512 reduces test time by executing 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.
