AE Amplifiers/Preamplifiers: KRN Services

The KRN AMP-xxBB-J series of wideband preamplifiers are designed to interface the KRNBB-PC sensor to your Digital Acquisition System or to AE Test System for signal capture and analysis.

The AMP-xxBB-Jx line provides power and a DC bias point to the current amplifier (jfet) integral to the KRNBB-PC sensor. Currently this preamplifier is available in 4 different configurations to suit your lab or AE test equipment needs.

The AMP-4BB-J & AMP-12BB-J preamplifiers come equipped with an internal universal 28 Volt DC power supply, or they can be powered from an external DC power source via a (switched) BNC connector mounted on the back panel. The AMP-4BB-J28 preamplifier is only powered from an external DC supply while the AMP-1BB-J preamplifier is powered from an AE Test System. For all models the user can select one of two different gain modes for operation. The “Cal Mode” provides -0.92 dB (x0.9)of preamplifier gain while “Test Mode” provides 27dB (35 dB for AMP-1BB-J) of gain over a broad spectrum of frequencies. Each preamplifier channel can be individually set to Cal or Test mode.
