| Our range of quality high frequency wide bandwidth amplifiers from Spectrum are
in a neat robust modular case and ideal for use as MHz 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 versions have the feature of a manually
adjustable voltage output offset together with exceptional dynamic low noise performance. |
|
- Very wide bandwidth from Hz to MHz
- Ampilifer modules with upper bandwidth (-3dB) limit of 10, 200 and 500 MHz
- 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 most models
- Manual output offset easily adjustable
- Standard sturdy BNC in/out signal cable connectors
- Suitable for all Spectrum A/D signal capture cards or similar amplification applications

|
 |
Delivery: The amplifier module requires a 230VAC to +/- 15VDC
power supply and power connection cables, this should be ordered
at the same time (part SPA.PW1-230). The AC power cable is
terminated in a type C euro connector, however for UK use we
automatically provide a neat converter socket (pictured).
We can supply a 120VAC power supply with US/Japan connector
as substitute.
