Low Noise Filter (N1294A-022)

Maximum output range: 210 V / 3 A (DC)

Output connector/connection: Banana, 2-wire/4-wire

Output / residual resistance: 0.3 Ω nominal (2-wire)

Small signal bandwidth: 2 kHz nominal (1 A and 3 A ranges), 800 Hz nominal

(100 mA range)

Noise

Voltage source

0.1 to 10 Hz: Same as voltage specification

10 to 20 MHz : 350 µVrms (20 V / 1.5 A range, 50 Ω load)

Current source

0.1 to 10 Hz: Same as current specification

10 to 1 MHz : 450 µArms (20 V / 1.5 A range, 0.67 Ω load)

Settling time

Voltage source

: 640 µs (2-wire/4-wire)

Current source

: 1.2 ms (2-wire/4-wire)

1. Time required to reach within 0.1 % of final value at open load condition. Step is 10 % to

90 % range. At 20 V range, 1.5 A limit/1.5 A range

2. Time required to reach within 0.1 % of final value at short condition. Step is 10 % to 90 %

range. At 1.5 A range, 20 V limit / 20V range

Load transient recovery time

Time to recover to within the settling band following a load change.

800 mA current change

Settling band ± 20 mV

Time 450 µs (2-wire), 650 µs (4-wire)

1. At a load change to change the flowing current from +100 mA to +900 mA, 10 V voltage force,

20 V range, 1.5 A limit.

Supported ranges:

Voltage: 200 mV to 200 V ranges (210 V maximum)

Current: 10 µA to 3 A ranges (3 A maximum)

Maximum capacitive load: 1 mF

Dimensions: 41.5 mm H x 58.2 mm W x 127.5 mm D (When the filter is inserted

to the output connector of B2961A/B2962A, the depth is 112.5 mm.)

Weight: 0.25 kg

Note:

* The 10 A pulse range and programmable output resistance capability are not

supported by external filters.

* For the current output, only DC is supported when using with external filters.

*The current measurement data monitored by the built-in voltage/current moni

tor can be influenced by the charge and discharge current of the capacitance

inside of the filters.
