| Description The Model 7200 is the latest of a long line of impedance measuring instruments. Two phase-sensitive detectors are used to extract and display both the parallel capacitance and conductance of the device under test. From the measured parameters the 7200 can calculate and display the equivalent parallel and series resistance, series capacitance, dissipation factor, and quality factor Q. Capacitance can also be displayed as a deviation from a selectable reference standard in % or pF units. The 7200 uses a software filter technique which averages consecutive measurements to achieve a stable display value. Test levels are programmable from 15 to 100 mV, making the 7200 suitable for a wide variety of semiconductor measurements. Up to 99 complete front panel setups can be stored and recalled in internal nonvolatile memory. Bias Voltage The 7200 accepts, measures and displays external bias voltage over a range of ± 60 volts. An internal bias supply is also included and is programmable over a ± 60 volt range. This bias capability, along with fast responding analog C, G and V outputs, makes the 7200 ideal for C-V and G-V semiconductor plots, as well as DLTS material studies. | Automatic Zeroing One key stroke zeros the 7200 for stray capacitance and loss. The 7200 is capable of zeroing up to 2000 pF. As a result, the maximum range of the instrument can be effectively increased to 4000 pF by first zeroing the 7200 with a 2000 pF specimen connected to the input. Special Functions A variety of special functions are provided to extend the operation of the 7200 to meet specific requirements. For example, the instrument can be forced to hold a particular measurement or bias range. The averaging filter length can be selected from no averaging up to 500 measurements. Special functions can also be used, in conjunction with external standards, to calibrate the instrument from the front panel or over the IEEE-488 interface. Bus Operation The 7200 is equipped with a full function IEEE-488 interface bus. The following can be remotely programmed: all panel functions, including special functions; store and recall panel setups; and zero and bias controls. For rapid data transfer, C, G and V information is available simultaneously. Front panel setups can be stored and recalled by program location. | |||||||||||||
