Looking for "voltage <=> current converter" equipment
(1/1)
huu_tri0101:
I'm looking for Laboratory equipment able to convert:

Voltage to current:
        Scale:
           1V -> 1mA
           1V -> 2mA
           1V -> 3mA
           1V -> 4mA
           1V -> 5mA
           1V -> 10mA
Voltage to Voltage
           1V -> 1V

Output power: <5W
Frequency: 10Hz to 20kHz

Thank you for your suggestions.

1). 1k resistor.
2). 2 1k resistors parralel.
3). 3 1k resistors parallel.
4). 4 1k resistors parallel.
5). 5 1k resistors parallel.
6). 100 Ohm resistor.
7). Piece of wire.
exe:
Google "Howland current pump" (supply side current source) or "current sink" (ground side). I'd suggest the second one if it is possible as howland pump requires matched resistors for good impedance.
