7200 Series Capacitance Meter
The 7200 is a sophisticated capacitance meter equally suited
for demanding R&D, as well as manufacturing applications. 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 non-volatile memory.
• Capacitance range, 0 to 2000 pF
Bias Voltage
The 7200 accepts, measures and displays external bias voltage
over a range of ±60 V. An internal bias supply is also included
and is programmable over a ±60 V 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
• Conductance range, 0 to 2000 µS
• Test frequency, 1 MHz crystal-controlled
• Test level, selectable 15, 30, 50, and 100 mV
• External bias ±60 V
• Standard programmable internal bias ±60 V
• Analog outputs proportional to both C and G and bias
• GPIB standard
maximum range of the instrument can be effectively increased

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.
