The Agilent/Keysight Technologies N6705C Modular DC Power Analyzer, 600 W, 4 Slots, Refurbished represents an entirely new instrument category for R&D engineers. It provides unrivaled productivity gains when sourcing or loading and measuring DC voltage and current into a DUT. Using the Keysight N6705C, R&D engineers can gain insights into the DUT’s power consumption in minutes without writing a single line of code. It provides an easy-to-use interface, with all sourcing or loading and measuring functions available from the front panel.

Modular System Based On DC Power Supply Or Electronic Load Outputs

The Keysight N6705C 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 N6705C is a mainframe that has four slots to accept one to four DC power or load modules.

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 ground and from each other.

Voltmeter/Ammeter: Meter View

Each DC power or load module in the Keysight N6705C 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). You can find the accuracy specification in the tables starting on page 17 under "Voltage Measurement Accuracy and "Current Measurement Accuracy."

Oscilloscope: Scope View

Each DC power or load module in the Keysight N6705C 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 autoranging, precision, and SMU).

The oscilloscope can be triggered on either voltage or current levels. Because the Keysight N6705C is an integrated instrument, the oscilloscope can also be easily configured to trigger on the start of an arbitrary waveform or to trigger when the DC power output is enabled. For example, to make an inrush current measurement on your DUT, you can set the oscilloscope to trigger on the DC output’s on/off key, set the trigger mode to single shot, and then turn on the DC output. This will immediately capture the current flowing out of the DC module into the DUT and give a picture of the inrush current of the DUT. This integrated functionality is not available when using a collection of separate test instruments on the test bench and is an example of how the DC power analyzer reduces setup time and complexity.

Data Logger View

The Keysight N6705C can also function as a data logger. Using the measurement capability built into each DC power or load module, the N6705C 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).

The maximum data log file size is ~2 gigabytes, which is approximately one billion readings. The data file can be stored on the N6705C’s internal non-volatile RAM or saved externally on a USB memory device.

The data logger display can be saved as a GIF file for use in reports. The logged data can be saved for viewing at a later time. Logged data can also be exported to a CSV file that can be read by most common data analysis software packages.

Arbitrary Waveform Generator

Each DC power output or load on the Keysight N6705C 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 N6705C 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.

For each waveform, you can set it to repeat continuously or you can specify the number of times the waveform is repeated.

For user-defined voltage and current waveforms, you can download up to 512 setpoints of voltage or current. With loads, waveforms can be generated in voltage, current, resistance, and power. For each setpoint, a dwell time is specified and output will stay (i.e., dwell) at that setpoint for the programmed dwell time value. For each of the 512 setpoints in the user-defined waveform, you can have a different dwell time from 0 to 262 seconds with 1 microsecond resolution. The module will step through the user-defined table of values, staying at each setpoint for the programmed dwell time, and then it will move on to the next point. User-defined waveforms can be imported from a CSV file or directly entered from the front panel of the DC power analyzer.

Constant-dwell voltage or current waveforms can also be generated, with up to 64000 programmable points. With loads, voltage, current, resistance, and power is available.
