Key facts
The ZES ZIMMER LMG600 Series of Precision Power Analyzers provides high-accuracy power measurements for demanding test applications. Its DualPath architecture enables simultaneous wideband and narrowband analysis up to 10 MHz. It measures precisely from very low power to complex multi-phase and high-power systems through configurable power channels and external sensors.
A 10.1" touchscreen with an intuitive user interface, built-in data logging, and customizable menus simplify operation and reduce setup time. Whether used in R&D, validation, or certification, it delivers consistent, traceable results for accurate power analysis.
Tailored precision where you need it
Not every measurement in a setup demands the same precision or bandwidth. The LMG600 Series supports four channel types (S, A, B, C) that can be mixed freely within the same chassis, ranging from the S-Channel with 0.015% AC accuracy and 10 MHz bandwidth down to the C-Channel for lower-frequency tasks. You configure the instrument to match the application — no over-specification, no compromises where it counts.
Channel flexibility
Wideband and narrowband values in a single measurement
Conventional power analyzers force a compromise: enable the anti-aliasing filter and lose wideband content, or disable it and risk aliasing errors in your FFT. The LMG600 Series resolves this with two independent A/D converters per channel — one for the filterless wideband signal, one for the narrowband signal after anti-aliasing. Both paths run in parallel, delivering RMS values, harmonics, and FFT results from the same signal simultaneously.
DualPath architecture
A user interface tailored to your application
Build application-specific views from the ground up: choose which electrical quantities and I/O variables to display, arrange them freely on screen, and add graphical elements such as wiring diagrams, photographs, or your brand identity. Pass/fail indicators and on-screen input fields for DUT-specific parameters can be embedded directly into the view, creating a measurement environment that even less experienced operators can use confidently.
Menu possibilities
Range extension of current measurements
Connected precision current transducers (PCT) identify themselves to the LMG600 via an integrated bus, automatically transferring scaling factors, delay compensation, sensor type, and last calibration date. The LMG600 Series power analyzers also power the sensors directly, eliminating separate supplies. There is no difference between direct and sensor-based measurements, and no manual fine-tuning required to obtain accurate results.
PCT sensor and interconnections
Bridging power analysis and the automotive world
The LMG600 Series is capable of sharing up to 128 measured values and variables directly over CAN bus including voltage, current, power, speed, torque, temperature and more. The interface works both ways: the LMG600 can also act on incoming CAN messages, with up to 128 trigger conditions available to start recordings, switch ranges, or initiate logging based on external events. No middleware, no manual data alignment.

Standards-conforming evaluation, end to end
The LMG Test Suite drives the LMG600 through EMC compliance tests according to - IEC/EN 61000-3-2/-12 (harmonics) - IEC/EN 61000-3-3/-11 (flicker) - EN 50564 / IEC 62301 (standby power). It works with any standards-compliant AC source, online or offline, and exports comprehensive test reports including all traceability information. Upcoming changes are incorporated as they are adopted.
LMG Test Suite
Mechanical and environmental data, perfectly synchronized
The optional PSI adds fast analog inputs, switching inputs and outputs, torque/speed/frequency inputs, and 32 analog outputs — all sampled in synchronization with the power channels. Torque, speed, temperature, and pressure can be acquired alongside voltage and current, and external devices can be triggered or driven directly from measured values.
No need to stop at seven channels
Multiple LMG600 units can be linked via sync cable to form a single virtual analyzer, automatically aligning cycle timing, system time, transient trigger events, and the state of energy integration. Whether you need eight channels or many more, the measurement remains coherent across all chassis with no manual reconciliation required.
From microamps to 32 amps without changing ranges
Compliance procedures such as IEC 62301 and EN 50564 require uninterrupted observation across widely varying load conditions. The LMG600 Series offers a continuous dynamic range from 500 µA to 32 A and 3 mV to 1000 V, with 18-bit resolution and a 10 ms minimum cycle time. Standby and full-load conditions can be characterized in a single, uninterrupted run, with 0.015% basic accuracy preserved even near the bottom of a range.
