Function Details
Output Filter and External Filter
Output Filter and External Filter
The channel has a built-in output filter to obtain clean source output without spikes,
noise, and overshooting. To set the filter, see “Output Filter dialog box” on page
4-29. Note, however, that using a filter may increase the channel settling time.
Also the channel can be equipped with an external filter (N1294A-020/021/022 low
noise filter, LNF). By attaching the filter to the output terminal, the B2961A/
B2962A can be used as a high resolution and high speed DC power supply or a DC
bias source for high frequency measurement instrument.
For using the external filter, see “Using the Low Noise Filter” on page 3-19 and
“External Filter dialog box” on page 4-29. And set the dialog box properly.
Conditions for using the external filter is shown below.
• Supported source mode: DC voltage source or DC current source
• Built-in output filter:
Filter State: ON
Automatic Filter: ON
• Programmable output resistance function: Unsupported
• Maximum output voltage/current for using HC-ULNF: 21 V / 500 mA
• Current ranges effective for using HC-ULNF: 1 mA to 1 A ranges
• Maximum output voltage/current for using ULNF: 42 V / 105 mA
• Current ranges effective for using ULNF:
In the current source mode: 10 nA to 100 mA ranges
In the voltage source mode: 10 A to 100 mA ranges
• Current ranges effective for using LNF:
In the current source mode: 10 nA to 3 A ranges
In the voltage source mode, high capacitance mode ON: 10 A to 3 A ranges
In the voltage source mode, high capacitance mode OFF: 100 mA to 3 A ranges
