Keysight (Agilent) 6643A 35V 6A Single Output System DC Power Supply

The Agilent 6643A Single-Output DC System Power Supply (GPIB) offers fast, low-noise outputs; built-in measurements and advanced programmable features; and protection features to ensure DUT safety. Specifications. DC Output: 0 to 35 V / 0 to 6 A (40° C). Programming Accuracy at 25° C ±5° C (Voltage / Current): 0.06% + 15 mV / 0.15% + 6.7 mA. Ripple and Noise (20 Hz to 20 MHz); Voltage rms: 400 µV. peak-to-peak: 4 mV. Current rms: 3 mA. Readback accuracy at 25° C ±5° C (percent of reading plus fixed): Voltage 0.07% + 25 mV, +Current 0.15% + 5 mA, –Current 0.35% + 12 mA. Load regulation: Voltage 3 mV, Current 0.25 mA. Line regulation: Voltage 1 mV, Current 0.25 mA. Transient Response Time: Less than 100 µs for the output voltage to recover to its previous level (within 0.1% of the voltage rating of the supply, or 20 mV, whichever is greater) following any step change in load current of up to 50% of rated current. Supplemental characteristics. dc Floating Voltage: Output terminals can be floated up to ±240 Vdc from chassis ground. Remote Sensing: Up to half the rated output voltage can be dropped in each load lead. The drop in the load leads subtracts from the voltage available for the load. Command Processing Time: Average time required for the output voltage to begin to change following receipt of digital data is 20 ms for the power supplies connected directly to the GPIB. Output Programming Response Time: The rise and fall time (10/90% and 90/10%) of the output voltage is less than 15 ms. The output voltage change settles within 1 LSB (0.025% x rated voltage) of final value in less than 60 ms. Down Programming: An active down programmer sinks approximately 20% of the rated output current. Modulation: (Analog programming of output voltage and current). Input Signal: 0 to –5V. Input Impedance: 10 k Ohm nominal. ac Input: (ac input frequency 47 to 63).

*This is a Web introductory price for one calibration of the Keysight (Agilent) 6643A. Price does not in most cases include measurement performance data. Pricing does include NIST traceable calibration and issue of a calibration certificate and calibration label. Pricing may vary slightly due to volume and location of laboratory supporting calibration. Volume pricing may apply. On-site fees may apply depending on logistics, location and volume of work to be completed during the visit.

dBc
dBc (decibels relative to the carrier) is the power ratio of a signal to a carrier signal, expressed in decibels. If the dBc figure is positive, then the relative signal strength is greater than the carrier signal strength. If the dBc figure is negative, then the relative signal strength is less than carrier signal strength.

Load Regulation
Load regulation is the capability to maintain a constant voltage (or current) level on the output channel of a power supply despite changes in the supply's load (such as a change in resistance value connected across the supply output).

Power Linearity
When changing the power level and measuring the differences (in dB) between actual and displayed power levels, the power linearity is ± half the span (in dB) between the maximum and the minimum value of all differences.

Settling Time
Settling time of an output device is the time elapsed from the application of an ideal instantaneous step input to the time at which the amplifier output has entered and remained within a specified error band, usually symmetrical about the final value.
