DMM7512

Two DMM7510s built into one compact enclosure

The Keithley DMM7512 Dual Channel 7.5 digit Sampling Multimeter combines two DMM7510, full-function, high accuracy and high sampling speed DMMs into a compact 1U high, full rack wide form factor chassis. The compact chassis saves rack space in high-instrument density, test systems. The small size does not compromise measurement performance.

High-resolution measurements on the smallest of signals

Each Keithley Digital Multimeter has identical functionality, and both are entirely independent of each other. The DMMs achieve a basic, one-year accuracy as low as 14 ppm for DC volts, 24 ppm for resistance, and 60 ppm for DC current. Sensitivities of 10 nV, 0.1 µΩ, and 1 pA ensure high-quality, high-resolution measurements on very small signals. In addition, each Keithley DMM has a wide range of functionality including voltage digitising, current digitising, and temperature measurements with resistance temperature detectors (RTDs), thermistors, and thermocouples.

With the Keithley DMM7512 dual channel capability, fast signal sampling, high-speed data transfer rates reaching up to 100,000 measurements/s, and internal execution of program test scripts, the DMM7512 reduces space and reduces test time in automated test systems.

Capture Low-Level Waveforms with the 1 Msample/s Digitiser

Avoid the need for a separate instrument to capture waveform parameters or ensure a waveform is within design limits by using the digitising function. Digitise either voltage or current and sample a waveform at a rate of up to 1 Msamples/s with the 18-bit digitiser. The digitising function employs the same ranges that the DC voltage and DC current functions use to deliver exceptional dynamic measurement range. With the digitiser’s 1 µV and 0.1 nA sensitivities, the DMM7512 is the best solution for measuring low-level waveforms such as wireless IoT battery current profiles and laser diode current consumption profiles.

Using the digitising function, the two DMM7510 DMMs can measure the current in all the operating states of a device including the sleep state and the current burst state when the device is transmitting. By using the two DMMs as synchronised digitisers, one for voltage and one for current, power can be accurately computed on time-varying waveforms.
