Analog Linear Driver with fast switching mode, Part No. ADLFM-10/100
This driver provides two modes of operation: ‘slow mode’ and ‘fast mode’. In ‘slow mode’ driver operates as a linear voltage to current converter and provides conversion of 0… +10 V input voltage range to 0 … +100 mA output current. Second mode allows to use VCVA as “on/off” fast modulator. In “fast mode” the driver applies a short negative voltage pulse to accelerate the fall time. Typical Response Function of the attenuation for VCVA is shown on the plot below.
Specifications for slow mode
Input signal: 0..+10 V;
Output current: 0…100 mA; Power supply: +/-12 V DC 120 mA(max); Control Input/Output connectors: SMA female. |

Attenuation response function for ‘slow’ and ‘fast’ modes
GPIB and RS-232 Driver, Part No. GPDVC-15/100/RS
This driver can operate via GPIB and RS-232 interfaces. User should send 12 bits code for setting desired attenuation. The driver converts sent code in biasing current in range of 0-100 mA.
Download GPDVC-15/100/RS manual for more detail.
Specifications
Input range: 12 bits; Output current: 0…100 mA; Power supply: 100-240 V AC; Control Output connectors: SMA female. |
