# Keithley DMM7512 Dual Channel 7½-Digit Sampling Multimeter

## Key Features At A Glance

-   Two independent 7½-digit DMMs in a 1U-high, full-rack-width chassis that minimizes rack space in high-density systems
-   Dual 1 Msample/s 18-bit digitizers capture waveforms or identify transients on voltage or current
-   Trigger a waveform measurement on a signal level, a rising or falling edge, a window, or a digital trigger
-   Store up to 27.5 million timestamped readings on a waveform
-   Basic one-year DC voltage accuracy as low as 14 ppm (24 ppm resistance, 60 ppm DC current)
-   10 nV, 0.1 µΩ, and 1 pA sensitivities for high-resolution low-level measurements
-   USBTMC-compliant USB, LAN LXI-compliant, and TSP-Link interfaces for automated test systems
-   Auto-calibration plus a two-year calibration interval reduce drift and life-cycle costs

The Keithley DMM7512 Dual Channel 7½-Digit Sampling Multimeter combines two full-function, high-accuracy, high-sampling-speed DMMs into a compact 1U-high, full-rack-wide chassis. Each DMM has identical functionality and operates entirely independently of the other, so the small form factor saves rack space in high-instrument-density test systems without compromising measurement performance. Each channel reaches a basic one-year accuracy as low as 14 ppm for DC volts, 24 ppm for resistance, and 60 ppm for DC current.

With 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 test time in automated test systems. Its 10 nV, 0.1 µΩ, and 1 pA sensitivities support high-resolution low-level measurements such as portable device sleep currents. Using the two DMMs as synchronized digitizers, one for voltage and one for current, power can be accurately computed on time-varying waveforms, and the instrument can measure current in all operating states of a device including the sleep state and the current burst state when the device is transmitting.

> **Important:** Input protection: 1010 V DC on all ranges and functions for the HI and LO terminals; 350 V for the sense HI and sense LO terminals; 250 V rated for the current input terminal.

> **Important:** The DMM7512 does not have a front panel display; the instrument has a built-in web browser with a virtual front panel that is displayed on a PC monitor through a LAN interface connection.

> Usage tip: pair the DMM7512 with the Keithley 2606B System SourceMeter SMU Instrument over TSP-Link to stimulate and measure multiple DUTs as a single integrated, script-controlled test system.
