The Keysight N6705 DC power analyzer is a modular system that can be tailored to meet specific test needs. At the heart of the DC power analyzer is the DC power or load module. The Keysight N6705 DC power analyzer is a mainframe that has four slots to accept one to four DC power or load modules. Each DC power or load module takes one slot, except for the N6750 high-performance auto-ranging and N6760 precision power modules that are ≥ 300 W, and N6792A which occupy two slots. This modular design gives you the flexibility to mix and match over thirty different modules to create a solution optimized to meet specific test requirements.

R&D engineers can invest in high-performance outputs where speed and accuracy are needed, or purchase basic performance outputs for simple DC power requirements. In the future, as your test needs change, you can purchase different modules and swap them into the DC power analyzer, thus creating a solution that protects your investment and grows with you.

Each DC power module and electronic load module output is fully isolated and floating from the ground and from each other.

Each DC power or load module in the Keysight N6705 DC power analyzer has a fully integrated voltmeter and ammeter to measure the actual voltage and current being sourced out of the DC output into the DUT. Because this voltmeter/ammeter function is built in, it is easy to make measurements without additional wires or the added complexity of current sense resistors or current shunts. The accuracy of the voltage and current measurements are based on the type of module that is installed (load, basic, high-performance, precision, or SMU).

In Meter View, all 4 outputs can be viewed simultaneously. Both the measured values and settings for voltage and current are displayed for each output.

You can also view an enlarged view of one channel, displaying many settings and measured values, for that channel. A summary is shown for the other three channels.

Each DC power or load module in the Keysight N6705 DC power analyzer has a fully integrated digitizer to capture the actual voltage-versus-time and current-versus-time being sourced from the DC output into the DUT. The digitized data appears on the large color display, just like an oscilloscope. Because this oscilloscope function is built in, it is possible to make current measurements without current sense resistors, current shunts, or current probes. This greatly reduces measurement setup complexity and provides for accurate and fully specified calibrated measurements. The accuracy of the measurements in oscilloscope mode is based on the type of power module installed (load, basic, high-performance auto-ranging, precision, and SMU).

The N6790A, N6760, and N6780 modules offer simultaneous digitizing of output voltage and output current, such that you can view a voltage trace and a current trace at the same time on the oscilloscope display. For all other module types, you can select to view either a voltage trace or a current trace on the oscilloscope display.

The Keysight N6705 DC power analyzer can also function as a data logger. Using the measurement capability built into each DC power or load module, the N6705 can continuously log data to the large color display and to a file. Data can be simultaneously logged on all four DC outputs. The accuracy of the voltage and current measurements depends on the type of module that is installed (load, basic, high performance, precision, and SMU).

Each DC power output or load on the Keysight N6705 DC power analyzer can be modulated by the module’s built-in arbitrary waveform generator. This permits the output to act as a DC bias transient generator or power arbitrary waveform generator. The maximum bandwidth is based on the type of module that is installed (basic, high-performance, precision, SMU, and loads).

The Keysight N6705 uses run-length encoding, where each point in the waveform is defined by the voltage setting and the dwell time or duration to stay at that setting. Waveforms can be generated by specifying only a small number of points. For example, a pulse would only take three points to define it.

Each mainframe has 4 module slots to hold modules. Each module occupies one module slot, except for the N6753A-N6756A, N6763A-N6766A, N6785A-N6786A, and N6792A which occupy two module slots.

Often, a DUT requires some high-power DC sources and several very low-power DC sources. In this case, you may choose to configure a system where the sum of the power modules installed in the Keysight N6705 exceeds the total power available from the Keysight N6705 mainframe. The power management features of the Keysight N6705 allow you to allocate mainframe power to the outputs where it’s needed, achieving maximum asset utilization and flexibility. This feature provides safety from unexpected and dangerous shutdowns that can occur with power systems without power management when operated in a similar way. For example, if your DUT requires 250 W on two of its inputs but only 10 W each on two auxiliary inputs, you can configure a system consisting of two 300 W DC modules and two 50 W DC modules. Although the sum of the module power is greater than 600 W, you can still use the Keysight N6705. Thanks to the power management feature, you can allocate the 250 W each to the two 300 W modules while you allocate only 25 W to each of the 50 W modules.

For basic DC applications – with voltages up to 150V

The Keysight N6730, N6740, and N6770 Series of DC power modules provide programmable voltage and current, measurement, and protection features at a very economical price, making these modules suitable to power the DUT or to provide power for ATE system resources, such as fixture control.

For applications where the power supply plays a critical role – with available power up to 500 W

The Keysight N6750 Series of high-performance, auto-ranging DC power modules provides low noise, high accuracy, and programming speeds that are up to 10 to 50 times faster than other programmable power supplies. In addition, Keysight has, for the first time, included high-speed test extensions in general-purpose power supplies. The high-speed test extensions offer an oscilloscope-like digitizer that simplifies system configuration and increases measurement accuracy when viewing high-speed transient or pulse events within the DUT. In addition, auto-ranging output capabilities enable one power supply to do the job of several traditional power supplies.
