Offset Drift
The temperature drift of the input offset voltage is one of the decisive characteristics for the quality of a DC voltage amplifier. FEMTO Voltage Amplifiers have the DC performance of precision amplifiers. Therefore, even the 100 dB gain is well suited for DC-coupling without the need for permanent offset voltage adjustments.

Bandwidth
The bandwidth of an ideal variable gain amplifier is independent of the gain setting which is very important for measuring fast signals and pulses. The bandwidth of FEMTO`s DLPVA Amplifiers remains constant at 100 kHz (-3 dB) up to the highest gain setting. Wideband noise can be reduced by switching the upper cut-off-frequency to 1 kHz.

Controls
Parameters, e.g. gain settings, bandwidth etc. can all be controlled by local switches directly on the amplifier. Operation is straightforward and the chosen gain setting is displayed by LEDs. For remote control, each switch is provided with a corresponding TTL-Bit. Mixed operation is also possible.

Flexibility
Six different DLPVA models offer a high degree of flexibility. Our customers can choose either a single ended or a true differential input. The input impedance is 1 MΩ or lower for our bipolar models and an exceptional high 1 TΩ for our FET models allowing measurements of signals from very high impedance sources. Finally the noise is as low as 0.4 nV/√Hz for the model DLPVA-100-BUN-S.
