Key Features
• Two high-precision, 7½-digit DMMs in a 1U high, full
rack width chassis
• No space requirements between instruments
minimizes rack space
• Capture waveforms or identify transients with two
1 Msample/s 18-bit digitizers
• Trigger a waveform measurement on a signal level, a
rising or falling edge, a window, or a digital trigger
• Store up to 27.5M timestamped readings on
a waveform
• Basic one-year DC Voltage accuracy as low
as 14 ppm
• 10 nV, 0.1 µΩ, and 1 pA sensitivities for making
high resolution low level measurements such as
measurements of portable device sleep currents
• High accuracy, low resistance measurements with
offset compensated ohms, four-wire measurement,
and dry circuit functions
• Auto-calibration improves accuracy and stability by
minimizing temperature and time drift
• USBTMC-compliant and LAN LXI-compliant
interfaces
• Reduce test time by executing test scripts with the
Embedded Test Script Processor, which saves PC
command communication overhead
• Tight synchronization between the two DMMs using
TSP-Link
®
communication
• Reduce life cycle costs with a two-year
calibration interval
The DMM7512 Dual Channel 7½-digit Sampling
Multimeter combines two 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. Each DMM 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 DMM has a
wide range of functionality including voltage digitizing,
current digitizing, and temperature measurements with
resistance temperature detectors (RTDs), thermistors,
and thermocouples. 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
reduces test time in automated test systems.
Capture Low Level Waveforms with
the 1 Msample/s Digitizer
Avoid the need for a separate instrument to capture
waveform parameters or ensure a waveform is within
design limits by using the digitizing function. Digitize either
voltage or current and sample a waveform at a rate of up
to 1 Msamples/s with the 18-bit digitizer. The digitizing
function employs the same ranges that the DC voltage
and DC current functions use to deliver exceptional
dynamic measurement range. With the digitizer’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 digitizing function, the two
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 synchronized digitizers, one for voltage and one
for current, power can be accurately computed on time-
varying waveforms.
