The CR-Z-110 and CR-Z-110-HV are charge sensitive preamplifier (CSP) instruments,based on Cremat's CR-110 CSP module. The CR-Z-110 has BNC connections for detector input, test input, preamplifier output, and detector bias supply. The CR-Z-110-HV is identical to the CR-Z-110 except that SHV connectors are used in place of BNC connectors in the detector input and detector bias supply connections. The CR-Z-110-HV is recommended when the applied detector bias exceeds +/- 500V.Maximum detector bias voltage using the CR-Z-110-HV is +/- 2000V.
