SRS SIM914 Preamplifier
DC–350 MHz bandwidth with two independent channels, gain 5 (14 dB) per channel, 6.4 nV/√Hz input noise, 50 Ω input/output and 3 ns overload recovery.
- DC to 350 MHz bandwidth
- Two independent amplifier channels
- Voltage gain of 5 (14 dB) per channel
- 6.4 nV/√Hz input noise
- 3 ns overload recovery
- Excellent phase linearity
The SIM914 350 MHz Preamplifier contains two wide-bandwidth, DC-coupled amplifiers, each with a gain of 5 (14 dB). Its fast rise time, low noise and excellent DC accuracy make it an ideal instrument for amplifying signals like those from photomultiplier tubes and photodiodes.
The gain stages of several SIM914s can be cascaded without creating oscillation problems.
Input clamping gives a 3 ns recovery time from a 10× overload.
Wide bandwidth, along with and 50 Ω input and output impedance, ensures a linear phase response across the entire frequency range, preserving pulse shapes.
