| Our range of quality high frequency wide bandwidth amplifiers
from Spectrum are in a neat robust modular case, ideal
for use as external MHz / GHz pre-amplifiers for the Spectrum
signal capture cards, or any similar high-speed applications
where very small micro or millivolt signals require high gain
amplification. All DC versions feature a manually adjustable
voltage output offset, together with exceptional dynamic low
noise performance. |
|
- Very wide bandwidth from Hz up to GHz RF frequencies
- Pre-amplifier modules with upper bandwidth (-3dB) limit of 10 MHz to 2.5 GHz
- Amplification of x10 (20dB), x100 (40dB) and x1000 (60dB)
- 50 ohm or 1 MOhm input impedance - (see data table below)
- Switchable AC/DC input coupling and dual gain settings on models up to 200MHz
- Manual output offset easily adjustable on models with DC coupling
- Standard sturdy BNC in/out signal cable connectors. SMA for GHz models.
- Suitable for use with Spectrum A/D signal capture cards or similar amplification applications
- 100 - 240V AC mains to DC converter supply unit included

Delivery: The pre-amplifier module also comes with a auto-ranging
100 - 240V AC to +/- 15VDC power supply and power connection cables.
The AC power cable is terminated in a type C euro connector, however for UK use we
automatically provide a neat converter that clamps over the euro end (pictured)
approved by BSI to all relevant standards. We can on request
provide a supply power supply with US/Japan mains connector as substitute.
