Model 70723 Wide Band Voltage Amplifier.
The 70721 and 70723 Voltage Amplifiers are optimized for use with our fast detectors of pulsed radiation. The output of PMT, Si, InGaAs, and HgCdZnTe detectors, or any other source of low voltage signals which will not be loaded down by the 50 Ω amplifier input impedance, can be amplified by these devices. The 70721 and 70723 bring these low level voltages to a value more suitable for displaying on an oscilloscope.
These amplifiers are usable with the following Oriel Detectors.
BNC input and output connections provide easy interface to detectors and data collection and display electronics. The 50 Ω input impedance of the amplifiers is designed to match the impedance of the BNC cables. This prevents the formation of electronic echoes due to reflections at impedance-mismatched interfaces. These echoes show up as additional features with delays of approximately 3 ns per foot of cable length.
The 70721 Amplifier requires a source of +15 VDC power and the 70723 Amplifier must be powered by an external ±12 V supply. Our 70703 Lab Power Supply was designed for this purpose. Or, you can use any low noise, linear, laboratory power supply.
