N1298C Low Noise Filter, 210 V/3 A
Product Fact Sheets
Low Noise Filter Minimize B2961B/62B Power Source Noise Performance
The Keysight N1298C Low Noise Filter (LNF) provides noise levels comparable to those of linear power supplies and also supports the B2961B/62B’s wide bipolar voltage and current ranges (up to 210 V/3 A). In addition, the LNF enables the B2961B/62B to drive capacitive loads of up to 1 mF.

Used together, the Low Noise Filter (LNF) and the Keysight B2961B/62B provide clean voltage sourcing equivalent to that of much costlier precision linear voltage and current sources. Best of all, this solution supports all of the output ranges (210 V@105 mA, 21 V@1.5 A and 6 V@3 A) while providing exceptional low noise performance.
The LNF also supports 4-wire connections to allow accurate sourcing and measurement far from the output terminals of the filter.
N1298A High Current Ultra-Low Noise Filter
A High Current Ultra-Low Noise Filter (HC-ULNF) is also available for the B2961B/62B. The HC-ULNF lowers the B2961B/62B’s noise floor and when used together the noise density of this solution is 1 nVrms/√Hz at 10 kHz for voltages and currents of up to 21 V and 500 mA.
N1298B Ultra-Low Noise Filter
An ultra-low noise filter (ULNF) is also available for the B2961B/62B. The ULNF lowers the B2961B/62B’s noise floor and when used together the noise density of this solution is 1 nVrms/√Hz at 10 kHz for voltages and currents of up to 42 V and 100 mA.
B2961B/62B 6.5 Digit Low Noise Power Source
The Keysight B2961B/62B is an advanced power supply/source. It can source either voltage or current with 6.5 digits of resolution while also monitoring both voltage and current. This makes it essential for a variety of measurement applications.
