The Agilent/Keysight Technologies N6763A Precision DC Power Module for N6701A/02A, N6700B, N6700C/01C/02C, and N6705C/15C Power Systems, 20 V, 50 A, 300 W combines a fast output with flexible controls and sophisticated measurements. The N6763A is more than a power supply; it is a stimulus/response instrument.

To fit in 1U, the N6763A use an advanced switch-mode design that offers the low output noise and fast output speed typically found on linear power supplies.

Low Noise Outputs

Careful attention has been paid to this design to ensure low normal mode noise (ripple and peak-peak) as well as low common mode noise. This switching power supply outperforms most linear power supplies on the market.

Fast Voltage Changes

Thanks to an active down-programming circuit to rapidly pull down the output when lowering the N6763A's output voltage, this power module can rapidly program both up and down in voltage.

Note that for smaller voltage changes the programming speed is less than 200 microseconds. These output speeds allow the N6763A to give maximum system throughput when your test calls for frequent changes in power supply voltage settings.

Autoranging For Flexibility

The N6763A gives you even more flexibility by providing autoranging outputs. This autoranging capability provides maximum output power at any output voltage up 60 V. This allows one power supply to do the job of several power supplies because its operating range covers low voltage, high current as well as high voltage, low current operating points.

The flexibility of autoranging is useful when the DUT operates over a wide range of voltages, when the ATE system needs to test a wide range of DUTs, or when margin is needed because the ATE power supply must be selected before final DUT power requirements are determined.

High-Speed Test Extensions

To make your testing go even faster, the N6763A offers High-Speed Test Extensions (HSTE). This enhancement to the DC power module extends the capabilities to include features similar to a built-in arbitrary waveform generator and a built-in oscilloscope.

Through the LIST mode of HSTE, you can download up to 512 setpoints of voltage and current. In LIST mode, you can program the output to execute a LIST of voltage and current setpoints. For each setpoint, a dwell time can be specified and the power supply will stay (i.e., dwell) at that setpoint for the programmed dwell time value. For each setpoint in the LIST, you can have a different dwell time from 0 to 262 seconds with 1 microsecond resolution. Then, you can trigger the module to begin executing the list. The module will step thru the list, staying at each setpoint for the programmed dwell time, and then it will move on to the next point. This speeds up execution by removing the computer I/O from the process. The result is an output that automatically changes according to the programmed list, just like an arbitrary waveform generator.

HSTE also provides an oscilloscope-like digitizer built into the power module to capture voltage and current measurements.For applications such as design validation of battery powered digital devices, the ability to capture dynamic information about the current flowing into the DUT allows designers to better understand the current drain on DUT batteries and optimize DUT power management during normal DUT operation and in DUT standby mode.

Precision Low-Level Performance

The N6763A additionally provides dual ranges on both programming and measurement. In the low range, it provides precision in the milliampere and microampere regions. This makes the N6763A ideally suited for semiconductor and passive device testing, or where a precisely controlled output and highly accurate, precise measurements are needed during test.
