Femto DLPVA-100-B-S Voltage Amplifier. Very good condition. With power supply. Unit powers on. Basic check O.K. No manual or other accessories. Purchaser responsible for proper use. As shown.
-
The DLPVA-100-B-S series from FEMTO is a family of low-frequency, variable-gain voltage amplifiers (DC to 100 kHz)
-
The “B” designation indicates a bipolar input stage (as opposed to FET)
-
The “-S” suffix often indicates a standard configuration (e.g. standard connectors, standard version) in FEMTO’s naming scheme
-
Bandwidth: DC to 100 kHz
-
Gain: switchable 20 / 40 / 60 / 80 dB (i.e. up to ×10000)
-
Input voltage noise: ~2.4 nV/√Hz
-
Input impedance: 1 MΩ (typical for bipolar models)
-
Offset drift: ~0.7 µV/°C
-
Output: low impedance (less than 100 Ω)
-
Output voltage range: ±10 V (into high impedance loads)
-
Controls: gain, coupling (AC/DC) switchable; local and remote control possible
