Description
N2820A | Current probe, auto sample, 50µA to 5 A, DC to 3 MHz, 2 channels
The Keysight (formerly Agilent's electronic measurement technology) current sample N2820A is equipped with precise, interchangeable measuring resistors to measure very small currents. This current sample is designed with two channels and has two input amplifiers with different amplification. The channel with the lower gain shows the complete current curve over time, while the channel with the higher gain is used for the precise investigation of current peaks and very small current fluctuations. Current curves from a minimum of 50 μA up to 5 A can be recorded depending on the measuring resistor used. The bandwidth is DC to 3 MHz in "Zoom in" mode and DC to 500 kHz in "Zoom out" mode.
The exchangeable, precise measuring resistor is fixed in the sample head, where the amplifiers are also positioned. 3 different resistor heads N2822A, N2824A and N2825A are available.
The dynamic range is 20,000: 1 or 86 dB for the high gain channel and 1000: 1 or 60 dB for the low gain channel. This sample is connected to two channels of the oscilloscope and shows the same signal - firstly with high amplification to find out subtleties, and secondly with low amplification in order to better recognize the signal curve "as such".
This combination of measurements is used for the investigation of input / output currents of ICs, for the investigation of the power consumption of mobile devices or for the control of the charging currents or circuits for mobile devices.
The samples are contacted by connecting them to the measuring points by cables. So that there is no need to solder in the circuit, plugs and connector pins are available. Only a 0.1 "hole spacing has to be provided in the layout in order to be able to solder or plug in the connector pins. Keysight (formerly Agilent's electronic measurement technology) calls this MBB (Make-Before-Break) what a simple interruption / connection At the same time, this contacting is very space-saving, advantageous for tightly packed circuit boards and small circuit boards, such as those used in mobile devices.
Lieferumfang
- Scope of delivery with the probe heads with the different measuring resistances 20 mΩ, 100 mΩ and a probe head, in which the user can install his own measuring resistor (min. 1 mΩ to max. 1 MΩ) and associated connection cables and plugs
- Warranty: 3 years
The interchangeable measuring resistors:
- N2822A with a measuring range of 250 μA to 5 A, a tolerance of ± 1% and a nominal resistance of 20 mΩ at a maximum load of 500 mW
- N2824A with a measuring range from 50 μA to 2.2 A, a tolerance of ± 1% and a nominal resistance of 100 mΩ at a maximum load of 500 mW; this head also offers less noise, higher bandwidth and greater sensitivity
- N2825A is a resistance head, the resistance value of which can be determined by the user in the range from 1 mΩ to 1 MΩ. It is important that the maximum power of the resistor used is not exceeded. The value of the selected measuring resistor must be entered into the oscilloscope so that the Y-axis is scaled in the correct units.
