KEITHLEY 7065

The Keithley 7065 Hall Effect Card is intended for those who want to assemble their own economical Hall test  systems. It also can form the foundation of a Hall Effect system. The sensitivity and capabilities of this card are unmatched by any other system or Hall Effect electronics package.

The 7065 is a signal conditioning card designed to buffer test signals from the Hall sample to the measurement instrumentation and to switch cur from a source to the Hall sample. When used with Keithley's 7001 scanner mainframe, the Model 7065 provides the switching capability to measure Hall voltages as low as 50nV and sample resistances in excess of 1012Ω.

The Keithley 7065 can be operated in either a low resistivity or a high resistivity mode. In the high resistivity mode, input impedance is greater than 100TΩ, input bias cur is less than 150fA, and output resistance is less than 60Ω. Input voltage ranges in both operating modes is +8V to €“8V. If higher voltage is desired, Keithley recommends using a 6220/6514 system. Cabling and sample connections must be carefully designed to make full use of the Model 7065's capabilities. Refer to Keithley's Low Level Measurements handbook for guidance in designing these connections.
