The FEMTO HLVA-100 offers a wide dynamic range of up to 80 dB. With a DC coupled input and a rise and fall time of just 5 ns the HLVA-100 is the ideal tool for the measurement of fast and high dynamic pulses. The input voltage noise is extremely low with just 2 nV/√Hz. The logarithmic gain curve offers high gain for small input signals and relatively low gain for high input signals. Therefore the HLVA-100 is the ideal amplifier for signals with high dynamic range and applications in which a signal compression is desired.
The HLVA-100 provides 3 possibilities of an input offset voltage correction (baseline correction). All three methods cancel both temperature drift dependent offset and small source voltage offset:
|Input Voltage Range||±20 µV ... ±200 mV and ±200 µV ... ±2 V|
Selectable by switch
|Scaling||12,5 mV/dB, 250 mV/decade (@ 50 Ω load)|
|Linearity||±1 dB (for pulse of min. 20 ns pulse width)|
|Input Noise Voltage||2 nV/√Hz|
|Input Voltage Drift||0.6 µV/°C|
|Input/Output||50 Ω, BNC|
|Rise/Fall Time||5 ns @ 40 dB step|
|Output Voltage Range||+50 ... +1075 mV typ. @ 50 Ω load
(if output is adjusted to 1 V at 100 mV input)
|Output Offset Voltage Range||±500 mV, adjustable by offset-trimpot|
|Baseline Correction||Acquisition time||30 µs (min. sample pulse width)|
|Baseline hold droop rate||1 µV/s (typ. @ 25°C)|
|Loop cut-off frequency||1.5 kHz|
|Power supply||±15 V, +100 mA/−150 mA,|
|Digital Control||TTL, CMOS, opto-isolated|

Offset adjustable by trimpot or external control voltage. Power supply via 3-pin Lemo® socket. A mating connector is provided with the device. Optional power supply PS-15 available. For further information please view the datasheet.
Typical Performance Characteristics
The DHPVA voltage amplifier series has been revised, resulting in the new models DHPVA-101 (DC - 100 MHz) and DHPVA-201 (DC - 200 MHz). Input voltage drift and noise are improved to an extraordinary low level while still convincing with a constant bandwidth at any gain setting.
The photoreceiver series HSA-X-S was broadened by two models featuring an improvement in noise performance of up to 40%. The output reflection coefficient was reduced by 8 dB at the same time.
