Current modulation
The DRV200 can be modulated from DC to 5 MHz using the SMA connector. A jumper
is used to select between 3 modulation gains:
DRV200-A-40
gain 1 : 200 µ/V
gain 10: 2 mA/V
gain 100: 200 mA/V
DRV200-A-200
gain 1 : 1 mA/V
gain 10: 10 mA/V
gain 100: 100 mA/V
Modulation range is +/-1 V and input impedance is 50
Ω
.
The modulation transfer function is shown below:
